+Agent 侧 MCP Apps 身份、授权、调用和通知入口；通过 McpUiSessionAccess 窄接口使用 session。
+
+- server 必须存在于当前会话的可信 MCP 配置，不猜测名称。连接 port 提供规范化来源身份与现有连接 generation；资源读取前后、请求执行前和审批后均验证。
+- McpUiInstances 是运行凭证唯一 owner：Agent runtimeId、单调 generation、不可猜 token、稳定 appIdentity。绑定 workspace identity/session/plugin/server/resource/scope/owner 和 Host 提供的已知账号上下文。同逻辑页面同连接的并发 open 幂等。
+- 页面只能选择工具名称与参数，不能选择连接、会话或实例。callTool 检查 app visibility，并复用已有 ToolExecutor 的校验、hooks、拒绝规则、会话授权与审批；app-only 工具可直接建立授权 entry，不要求暴露给模型。原始 MCP 结果直接返回，不产生自动对话或 transcript row。
+- 执行固定已验证的连接代际，不触发连接重建、OAuth 自动恢复或工具重放。取消到达底层 signal；取消不回滚外部已发生操作。
+- NDJSON 对完整凭证绑定的 MCP App 请求允许独立执行；长调用不得阻塞取消、关闭、审批及其他页面。普通会话请求保留串行队列，Agent 实例与调用登记负责并发终态。
+- 调用接纳时占用 callId；重复接纳、取消和回包幂等，终态之后拒绝迟到结果。close 先移除凭证，再 abort、取消调用、注销工具和资源订阅。onlyIfIdle 与调用 pin 在同一 owner 原子裁决。
+- App-provided tools 的现有同 server 最近登记策略保留；模型 entry 在审批前固定并 pin 对应实例。live-only 调用与取消携带完整凭证，不入持久化/replay。保留 5 秒认领、30 秒执行期限；执行只发生一次。
+- 资源订阅通知携带完整凭证，断连/来源变化/会话退出时撤销；不向旧实例或替代页面投递。模型和页面两方向的取消均使用官方 MCP/SDK signal。
+- resources/read 面向 UI 的结果移除 \_meta；总大小 8 MiB、MIME 白名单、blob MIME 必填，违反时返回明确错误而非截断。
+
+页面生命周期不新增 SQLite 表、不持久化 widgetState，不改变普通会话 CommandInbox、Host owner/lease、continuous 或 replayable 通道。
+
+- Sampling 操作表是采样接纳/取消/终态的唯一 owner，绑定完整实例和连接代际；先 pin 后执行，同代 operationId 不重放，失效立即终结、清账本。每实例/任务/Agent 并发上限 1/4/8，60 秒绝对期限，单实例账本最多 4096 项。采样沿用任务模型/权限，无新审批/会话/历史；只保留用量及诊断。

+name: visualize
+description: "Create visualizations and interactive tools directly in conversation. Proactively use to show how something works; explore 'what happens when', 'what changes', or 'help me understand'; compare or inspect; create simulations, maps, charts, graphs, and mockups. Use standard tools for static scientific figures."
+---
+
+# Visualize
+
+- A request for a new standalone file, website, app page, component, or other project change is not an in-conversation visualization request, even when the deliverable contains charts or interactive content.
+- A request to preview, explain, or explore a proposed interface in the conversation is an in-conversation visualization request.
+- Create a visual only when the user needs to see or explore it in the conversation and it materially improves the explanation. Do not create an inline visual merely because the request involves data, charts, or an interactive page.
+- Use a normal Markdown table when the user asks for a table; return it directly and do not create a visualization file.
+- Use Mermaid when labeled nodes and edges fully explain a static structure; return a normal fenced Mermaid block and no visualization file. Use HTML for dynamics, spatial motion, adjustable inputs, and other visuals.
+- Work silently unless blocked or the user explicitly asks for progress. Never send commentary or progress updates while reading this skill or writing or updating the file; the final response must be your first user-facing message.
+- In user-facing prose, describe only what the visual helps the user see or decide. Keep it concise and do not repeat information already clear from the visual. Never announce this skill, a visualization surface, widgets, HTML, SVG, scripts, local files, inline data, or implementation details.
+
+## Read the complete skill
+
+Read this file in full before authoring. Reread truncated ranges in smaller calls. Copy into every compaction summary: `Reload the full visualize skill before creating or updating a visualization.`
+
+## Inline HTML output contract
+
+### File
+
+- For each new or updated visualization, choose a concise ASCII lowercase-hyphenated title and write `<title>.html` in an explicitly writable, durable, task-owned location. Prefer the thread-scoped visualization directory when it appears in the writable roots or is explicitly supplied by the host. Do not write inline fragments into the project; if no visualization directory is supplied, inline rendering is unavailable.
+- Never add `sandbox:` links to inline visualization HTML unless the user specifically requests a download.
+- Do not choose system temp as a separate fallback. Write access alone does not guarantee that the conversation can read the file.
+- Use the absolute path on the executor that creates the file. Never assume `~/.ccbuddy` is writable beyond the session directory explicitly supplied by the host.
+- Build the visual in the conversation. Use the open project when the user asks for a site, app page, component, or change to existing project files.
+
+### Fragment
+
+- Write only an HTML fragment: no `<!doctype>`, `<html>`, `<head>`, or `<body>`.
+- Write literal markup: use `<div class="card">Hi</div>` plus a real newline, never `<div class=\"card\">Hi</div>\n`. Never embed the fragment in an inline Python, JavaScript, or shell string. Read it back; rewrite literal `\"` or `\n`.
+- Keep CSS and JavaScript in the fragment only when base classes are insufficient. Load static resources only from the CDN allowlist. Never use `fetch`, XHR, WebSocket, or other API calls.
+- Give the fragment root a unique ID and select it with `document.getElementById(...)`. Never derive the root from `document.currentScript`; scripts may sit outside the root.
+- Keep visualizations under 1 MB. Aggregate, bin, downsample, reduce precision, or drop unused fields from large inline datasets.
+- Check that JavaScript has no undefined identifiers, every queried element exists, and the primary interaction updates the visual. The bundled `python3 scripts/render.py <absolute-fragment-path> [<destination>.html] [--serve]` can wrap a fragment as standalone HTML or temporarily serve it for browser inspection when a preview would help with layout, theme, or runtime behavior. The rendered preview places the fragment inside a sandboxed iframe: scope Playwright locators to `page.frameLocator("iframe")` and evaluation to that frame.
+
+### Content and response
+
+- Keep the fragment focused on the visualization. Do not include explanatory paragraphs, formulas, instructions, or narrative callouts. Include only necessary labels, legends, values, and accessible text alternatives.
+- Use the normal response flow. Put any necessary concise explanation outside the fragment, and add this visualization content reference on its own line where the visual should appear, using the absolute executor-side file path:
+
+```text
+visualize{"path":"<absolute-path>/<title>.html"}
+```
+
+- Add `"mode":"wide"` for a full-screen desktop app mockup, including its application shell. For other visuals, add it only when several compact chart panels must remain side by side for direct comparison and would be unreadable at the normal width. Never widen a single plot, map, grid, diagram, or timeline merely because it is dense. Keep contained mockups, dialogs, and mobile screens at normal width; stack separate self-contained views vertically. Visualizations fill the available conversation width; the host does not impose a separate card width cap:
+
+```text
+visualize{"path":"<absolute-path>/<title>.html","mode":"wide"}
+```
+
+- Whenever you create or update an inline visualization, include its content reference only in that same turn's final response (never in commentary or progress updates), even when editing an existing file or reusing a path shown in an earlier turn.
+- The JSON object may also include a `title` when needed.
+- Emit only the content reference for the fragment. Never announce it as an artifact, website, output, attachment, link, or download, and never add a Markdown link to it. Do not append a Markdown table or repeat the visual's data; add at most one short conclusion when the user needs an explanation.
+
+### External resources
+
+- Floating UI Core 1.7.3 / DOM 1.7.4, Lucide 1.17.0, and D3 7.9.0 are bundled. Keep their prescribed script URLs unchanged: the Desktop host resolves those exact URLs locally, and standalone export embeds the files. Use a literal `<script src="...">` for D3 so exports remain offline; do not add another copy or fetch a fallback. Other versions, query strings, libraries, fonts, and map data are not bundled by this rule.
+- The CSP allows only `cdnjs.cloudflare.com`, `esm.sh`, `cdn.jsdelivr.net`, `unpkg.com`, `fonts.googleapis.com`, `fonts.gstatic.com`, and `fonts.bunny.net`. Other origins are blocked and fail silently.
+
+## Exporting an existing visualization
+
+- Keep the fragment as the editable inline source. When the user explicitly asks to save, export, or publish a visualization that is already shown in the conversation, render it with `python3 scripts/render.py <absolute-fragment-path> <destination>.html`.
+- Apply this export flow only when the user explicitly asks to turn the existing inline source or visualization into a website. For a general website request, build a new responsive site in the output directory or open project, without applying this skill's guidance.
+- Keep only `window.ccbuddy.widgetState` and `window.ccbuddy.setWidgetState` calls from window\.ccbuddy.\* when exporting: the standalone wrapper supplies fallback state storage. Replace other host-only interactions before using the standalone HTML outside CCbuddy.
+- The CCbuddy inline host does not provide Sites publishing. Export standalone HTML when requested; use an available hosting workflow only when the user asks to publish.
+
+## Runtime styles
+
+### Color
+
+- In each color pair, the base token is a surface and its `-foreground` token is the content on that surface. `--muted` is a surface fill; use `--muted-foreground` for secondary text.
+- Make every fill, stroke, text, border, shadow, chart, and canvas color theme-aware. Never hardcode light or dark palettes such as white panels, off-white backgrounds, black text, slate strokes, or Tailwind color literals.
+- Keep text readable against its actual background. Muted or secondary colors must retain clear contrast; never use `.text-muted` inside `.card` or another filled container unless its background preserves that contrast.
+- Available theme variables include `--background`, `--foreground`, `--card`, `--card-foreground`, `--popover`, `--popover-foreground`, `--primary`, `--primary-foreground`, `--secondary`, `--secondary-foreground`, `--muted`, `--muted-foreground`, `--accent`, `--accent-foreground`, `--destructive`, `--border`, `--input`, `--ring`, `--blue`, `--orange`, `--green`, `--red`, `--purple`, and `--yellow`. Use `currentColor` inside SVG.
+- Never add decorative borders, outlines, or strokes to progress tracks, meters, bars, stacked segments, or other filled quantitative marks. Use a subtle neutral or translucent track and distinguish marks with fill, contrast, spacing, or opacity.
+- Use `--viz-series-1` for one measure or active state. Use `--viz-series-2` through `--viz-series-6` only for important persistent category, series, or status identity; never give every peer a different color by default.
+  - For categorical tiles or nodes, prefer a soft low-opacity series fill with a neutral or transparent border; never color every outline.
+  - Keep mappings stable and pair color with labels, shapes, or line styles.
+  - Secondary series colors are theme-derived; never assume hues or use them decoratively.
+- When color encodes a category or series, apply it consistently to the corresponding visual marks—not just the legend—and keep large-area fills subtle.
+- Use series colors only for chart lines, marks, and legend swatches. Keep values, axis text, and direct labels in `--foreground` or `--muted-foreground`.
+- Keep chart grids and inactive structure thin and neutral. Use 1-2px neutral structural paths; never thicken, dash, or double-stroke the whole structure.
+- Use `.btn-primary` for high-emphasis actions; its neutral fill is supplied by the utility. Use `--primary` and `--primary-foreground` for filled selected, active, or pressed controls. Reserve `--accent` and `--accent-foreground` for subtle interactive surfaces and soft highlights. Buttons with `aria-pressed="true"`, `aria-selected="true"`, or `.is-selected` already use the primary pairing; `.nav-pills .nav-link.active` keeps selection neutral.
+
+### Typography
+
+- Scale type with `--font-size-base`. Use normal text by default and `.text-small` only for secondary annotations; at the default scale these are 14px and 12px. Never make supporting text smaller than 11px.
+- `h1`, `h2`, and `h3` are available; use one concise visible heading for a self-contained chart or graph, with short panel headings only when needed. Do not restate the prompt or add a redundant title to other visualizations.
+- Use only weights `400` and `500`. Never set custom font sizes or line heights.
+- Use `.tabular-nums` on changing or aligned numbers. Avoid it for editorial or decorative numerals.
+
+## Composition
+
+Choose the smallest composition that fits.
+
+- Prefer interaction detail over permanent panels, toolbars, repeated legends, or long stacks. Add only requested controls, use one mechanism per state, and never invent search, filter, or reset controls.
+- Keep filters, selections, and other presentation-only interactions local. For drill-down actions that ask CCbuddy to investigate or explain selected data, call `await window.ccbuddy.sendFollowUpMessage({ prompt, title })`, where the optional `title` is a concise confirmation-dialog heading of up to 250 characters. Include the selected values and requested investigation in the prompt, and label the action clearly.
+- Show only metrics that explain the requested behavior. Put live values in control headers or on the visual before cards. Treat maxima as ceilings, not targets. Never invent qualitative scores, status cards, or secondary fact grids to fill space.
+
+### Remembering inline interaction state
+
+- Read saved state from `window.ccbuddy.widgetState` when rendering. Listen for `ccbuddy:set_globals` and apply `event.detail.globals.widgetState` when present. Use defaults for missing or incompatible state.
+- After meaningful interactions, call `window.ccbuddy.setWidgetState({ modelContent, privateContent }).catch(() => {})`. Updates are acknowledged after the host persists them. Both fields accept JSON or `null` and may be omitted (treated as `null`). Each call replaces the snapshot; keep it under 16 KiB. Never save on load or state events.
+- Put choices useful for follow-up questions in `modelContent`, UI details worth restoring in `privateContent`, and transient or recomputable values in memory. Only `modelContent` may reach the model: delivery is best-effort and not guaranteed across clients. Never rely on it; saving never starts a turn. No secrets or images.
+
+### UI mockups
+
+- For alternative designs of the same component or screen, read [Variant carousel](tweak.md#variant-carousel), even when design controls are not requested.
+- Include a few thoughtfully chosen design alternatives whenever they would help the user explore a mockup, without waiting for the user to ask. Read [tweak.md](tweak.md) and bind useful options with the host-provided `Tweak` helper. Keep ordinary mockup interactions local; do not add design controls to charts, explainers, or simulations unless requested. Do not render a second controls panel or open annotation mode automatically.
+- "In the widget" means the in-conversation visualization, not a widget inside the depicted product.
+- Use product and platform context already available in the conversation; don't search the project to render a mockup. Match the product's chrome, navigation, typography, colors, and content. If its design is unavailable, infer one from the platform and request.
+- NEVER use visualization CSS variables or utility classes inside a mockup (for example, `--card`, `--font-size-base`, `.card`, or `.btn`). Define root-scoped, product-specific colors, typography, surfaces, and controls instead. This rule overrides all general visualization guidance.
+- Keep only the surrounding conversation surface transparent. Give product windows, cards, menus, and popovers opaque backgrounds, and stack overlays above the product content.
+- Follow the host's active appearance with product-specific `light-dark(<light>, <dark>)` colors unless a fixed theme is requested.
+- **Contained mockup:** Frame a component, dialog, small feature, or mobile screen as a compact product surface. Add `.viz-dotted-background` to the surrounding preview area or carousel root for a quiet, theme-aware dot grid. This preview-only class is an exception to the mockup utility rule; keep it outside the product UI and leave full-page mockups, charts, and explainers plain.
+- **Full-page mockup:** Render a desktop window, application shell, or page at full width without an additional visualization card.
+- Put app-wide navigation and pickers in the app chrome, and local controls in their component. Omit single-option pickers. Show realistic states, not invented dashboards, filler cards, or oversized icons.
+
+### Calendar
+
+- Use the bundled compact `<viz-calendar>` for a day schedule. Read [Calendar](widgets/calendar.md) and start from the [example](examples/calendar.html). Supply verified dates and events; the component handles durations, overlap lanes, and responsive layout. Short blocks show the title; hover, focus, or tap reveals the full title, time, and detail. Do not stretch the schedule to fit secondary text or wrap the element in another card.
+
+### Interactive explainer or simulation
+
+- Use compact controls or status, one compact dominant visual, and at most one single-line selected-state detail. Default to no summary cards; allow up to three only when changing metrics are central.
+- Crop empty space and fit the available inline width. For step-throughs, add only requested step controls and update one current visual; never add parameter controls, formulas, metric cards, or side-by-side steps unless asked.
+
+### Graphs and plots
+
+- Use D3 for data-rich Cartesian or statistical plots and handwritten SVG for simple, directly labeled values. Keep diagrams, simulations, and maps under their existing guidance. Load the bundled version on demand with `<script src="https://cdn.jsdelivr.net/npm/d3@7.9.0/dist/d3.min.js"></script>` before using `d3`.
+- Render the figure, legend, and subplots directly on the transparent host surface. Frame only the SVG plot area; never wrap charts in `.card`, rounded panels, filled backgrounds, or shadowed containers.
+- Give the figure a concise visible title. Render each Cartesian subplot in its own responsive SVG with a matching `viewBox`, a thin frame, and visible `text.axis-title[data-axis="x"]` and `text.axis-title[data-axis="y"]` showing quantities and units.
+- Set each SVG `viewBox` from its own container's measured width, redraw with `ResizeObserver`, and reserve at least 64px for the y axis. Never scale down a fixed-width `viewBox`.
+- Derive padded domains with `d3.extent(...)` over all observations, uncertainty, and references. Inset scale ranges for marker radii and keep every path inside `rect[data-chart-frame]`; never draw endpoint connectors outside the frame or guess or hard-code the domain.
+- After every draw, measure tick, axis, and value-label bounds together. Leave 4px between labels, anchor edge labels inward, and remove optional annotations first. At 360px, show at most four x ticks and stack panels.
+- Prefer `--viz-series-1` through `--viz-series-6` for chart series; use `--foreground` and `--border` for neutrals, cycle the six series tokens when more are needed, and never use literal or fallback colors. Give every SVG label `fill: var(--foreground)` and `font-size: 12px`; never shrink labels below 11 screen pixels. Stack subplots when their labels no longer fit.
+- Keep observations, trends, and important values visible. Use bands for dense uncertainty, whiskers for isolated estimates, and one compact, wrapping legend. Render one real `<button type="button" aria-pressed="true">` per series with a small swatch and neutral text; toggle its line, markers, and tooltip row together. Keep buttons transparent, borderless, and indistinguishable from inline text; never use `.btn`, pills, badges, rounded borders, or filled and selected backgrounds.
+- Share one root-relative, pointer-transparent `<div class="tooltip" role="tooltip">` using `--popover` and `--popover-foreground`. In each multi-series SVG, give the full-plot overlay both `data-chart-hit` and `data-chart-hover-overlay="cross-series"`. Keep the `data-chart-hover-guide` at the exact cursor x, interpolate every visible series there, and show one aligned `data-chart-hover-marker` and tooltip row per visible series; never snap the guide to a nearby sample. Let touch users pin the same cross-series details without requiring hover.
+- Find ordered observations with `d3.bisector(d => d.x).center(values, x)`; never pass an accessor to `d3.bisectCenter`.
+- Give isolated marks transparent `data-chart-hit` targets at least 32 screen pixels across on fine pointers and about 44px on coarse pointers; use one nearest-point overlay for dense scatter.
+- For named numeric data and one-off analyses, start with the plot. Put values and takeaways on its marks, axes, or annotations. Never add a KPI row, controls, cards, or panels unless those UI elements are explicitly requested.
+- For sequences or parallel work, use aligned lanes on one time axis. Encode phase and resource in the marks; annotate totals, waits, and bottlenecks on the axis or lanes, not above the plot.
+- For distributions or multi-metric comparisons, use shared-scale facets or small multiples. Render every requested dimension simultaneously; never hide one behind a toggle.
+
+### Maps
+
+- Let the map dominate the composition. Use at most one compact selection/detail area and only requested controls.
+- Always project published GeoJSON/TopoJSON and sourced longitude/latitude with `d3-geo`; never hard-code or hand-draw geographic outlines. Use schematic maps only when asked.
+- For world countries, import `https://esm.sh/@d3-maps/atlas@1.0.0/world/countries/countries-110m` and convert it with `topojson-client@3.1.0` using `feature(world, world.objects.features).features`. Join input ISO3 directly to `feature.properties.id`, which is already ISO3; do not convert it to numbers.
+- For US states or counties, use `https://cdn.jsdelivr.net/npm/us-atlas@3/counties-10m.json/+esm`. For ZIP/ZCTA or city boundaries, download official Census or local open-data GeoJSON; do not guess sibling atlas paths or import raw JSON as JavaScript.
+- Keep maps geographically legible: for local points, fetch published neighborhood, street, or comparable geometry; a blank field or lone administrative outline is not a basemap. Show the full city or region behind points or partial choropleths, and frame the locations with modest padding.
+- Include the verified geometry in the final HTML. Open it before replying and fix blank basemaps, failed imports, missing labels, or unprojected points.
+
+### Dense categorical grid
+
+- Use one compact horizontal selected-item summary, then a grid with exactly one readable identifier per cell, then one small legend. Render only that identifier as visible cell text; put all other metadata in an accessible label or one summary line, not badges or fact grids. Allow only selection unless asked.
+
+### Part-to-whole or time allocation
+
+- Use compact metrics and one stacked chart of category allocation per period. Never substitute totals-only bars or duplicate it as a heatmap and totals chart.
+
+## Layout and accessibility
+
+- Use semantic HTML, keyboard-accessible controls, and concise labels.
+- Use `aria-live="polite"` for dynamic results, selections, and simulator updates. Use `role="alert"` for validation errors. Do not announce every hover or animation frame.
+- Keep the top-level surface transparent and unframed, and fill the available conversation width. Fill the conversation parent and support widths down to 320px. Stack side-by-side content when it no longer fits.
+- At every supported width, text, controls, cards, toolbars, and dynamic content must fit without overlap or clipping. Reflow by stacking or wrapping; use `.table-responsive` only when table columns cannot fit. The host sizes the frame to its content, so avoid fixed outer widths, other horizontal overflow, internal scrolling, `position: fixed`, and viewport-height layouts.
+- Size every SVG from its actual container. At narrow widths, reduce ticks, declutter annotations, and keep visible text at least 11 screen pixels; never shrink a fixed-width `viewBox`.
+- Keep native tab order; never add `tabindex`.
+- Use native `button`, `input`, `select`, and `textarea` elements with matching utilities; never recreate controls.
+- Keep browser or utility focus styles; never override them.
+- On coarse pointers, provide non-overlapping effective targets about 44px by 44px without breaking 320px layouts; visible icons and marks may stay small. Keep fine-pointer controls compact, and let shared utilities own touch sizing and at least 16px editable-field text.
+- Keep essential content and actions available without hover.
+
+## Design system
+
+- Let utilities own geometry, appearance, and interaction. Use the matching utility for every button and form control. Never restyle utilities, descendants, or pseudo-elements: no custom sizes, spacing, borders, radii, shadows, colors, or interaction states.
+
+### Surfaces and layout
+
+- `.card`: The only card-like HTML surface. Use its base class unchanged for a necessary numeric summary, selected-item summary, or bounded interactive field. Before adding a fill, border, radius, or shadow to any layout container, either use `.card` or leave it transparent and unframed; never recreate card chrome on rows, panels, tiles, sections, or wrappers. Keep charts, maps, diagrams, tables, controls, and the whole visualization unframed. Never nest cards; show 2-4 summaries near the top only when useful. Structural groupings and repeated content are not bounded interactive fields. Organize them with layout or visual marks, not container chrome.
+- `.viz-stat`: Use a summary `.card` with one muted label, one `.viz-stat-value`, and at most one short context or delta line.
+- `.viz-grid`: Use for peer metrics or choices instead of a custom grid. It creates as many equal-width columns as fit and stacks when narrow. Never use it for the whole visual or a horizontally scrolling card row. Keep groups to 2-3 columns at 736px and controls in a separate row.
+- `.viz-row`: Use as a wrapping horizontal group with centered related values or inline actions that may wrap when narrow.
+- `<hr>`: Use a native horizontal rule for a subtle theme-aware separator.
+- `.nav.nav-pills` + `.nav-link`: Use the accessible, interactive [Tabs](#tabs) API below.
+- `.progress` + `.progress-bar`: `<div class="progress" role="progressbar" aria-label="Progress" aria-valuenow="25" aria-valuemin="0" aria-valuemax="100"><div class="progress-bar" style="width:25%"></div></div>`
+- `.viz-tile`: Add to a selectable dense-grid `.btn`; it stretches to fill its grid cell, preserves category fill, and uses an accent ring instead of solid selection. Never add another selected, pressed, border, outline, or shadow rule.
+- `.viz-badge`: Use as a compact display-only accent pill for a short status, category, or value; never as a button.
+- `.viz-controls`: Use as a wrapping row for controls affecting the same visualization. Keep button groups compact. Put labeled fields directly inside as `.form-label`; fields form at most two columns and stack when narrow.
+
+### Tabs
+
+- `.nav.nav-pills[role="tablist"]`: Group content-width native `.nav-link[role="tab"]` buttons and label the group with `aria-label`. Add `.nav-justified` only when tabs should share and fill the row equally.
+- `.nav-link[role="tab"]`: Give each button a unique `id`, `type="button"`, `aria-controls`, and `aria-selected`. Mark the initial tab `.active` and `aria-selected="true"`; use `disabled` or `aria-disabled="true"` when needed.
+- `[role="tabpanel"]`: Match `id` to its tab's `aria-controls`, set `aria-labelledby` to the tab's `id`, and mark inactive panels `hidden`. Tabs can have separate panels or point to one shared panel.
+- Tab behavior is already implemented by the JavaScript runtime and does not need to be wired.
+
+```html
+<div class="nav nav-pills" role="tablist" aria-label="Platform">
+  <button class="nav-link active" id="mac" role="tab" aria-controls="mac-panel" aria-selected="true" type="button">macOS</button>
+  <button class="nav-link" id="linux" role="tab" aria-controls="linux-panel" aria-selected="false" type="button">Linux</button>
+</div>
+<div id="mac-panel" role="tabpanel" aria-labelledby="mac">macOS content</div>
+<div id="linux-panel" role="tabpanel" aria-labelledby="linux" hidden>Linux content</div>
+```
+
+### Controls
+
+- Use `.cursor-interaction` on custom interactive elements, including locally styled widget controls. It follows the host cursor preference; never hardcode `cursor:pointer`. Shared controls already apply it. Preserve text, drag and disabled cursors for those states.
+
+- Place related inputs and buttons on one row, aligned at their vertical centers. Put labels and values on a separate row above them.
+- `.btn`: Use for a content-sized secondary action. Add `.btn-primary` for one main action per control group or `.btn-ghost` for low emphasis.
+- `.btn-block`: Add to a `.btn` only when the action should intentionally fill the available inline space. Never use it for ordinary row actions.
+- `<a>`: Use for links. Add `.btn` to style a link as a button.
+- `[data-tooltip]`: Use for concise supplementary plain text on static or dynamic triggers; the sandbox handles hover, focus, and touch and creates `.tooltip` elements. Keep essential content visible and triggers labeled. Never use `title`, custom markup, or initialization. Example: `<button type="button" data-tooltip="Reset view">Reset</button>`.
+- When a visible label is truncated, put its full text in `data-tooltip` on the existing accessible trigger so hover, focus, and tap reveal it. The bundled calendar does this automatically.
+- `[data-tooltip-placement]`: Optionally prefer `top` (default), `right`, `bottom`, or `left`; collision handling may flip it.
+- `.form-check`: Prefer a wrapping `<label class="form-check">` around the native `.form-check-input` and `.form-check-label` text so the whole row is tappable. An explicit label with matching `for` and input `id` also works.
+- `.form-switch`: Add to `.form-check` around a native checkbox.
+- `.form-control`: Pair a native text, date, file, or color input—or a textarea—with `.form-label`.
+- `.form-control-color`: Add to `.form-control` for a compact native color input.
+- `.form-select`: Pair a native select with `.form-label`.
+- `.form-range`: Pair a native range with a visible label; put its current value and units immediately before it.
+
+### Tables
+
+- `.table`: Use on a semantic table for a quiet, unframed data view. It provides wrapping cells and subtle horizontal dividers without vertical gridlines. Use sentence case for headers.
+- `.table-responsive`: Wrap a table when its columns cannot fit at narrow widths. It contains horizontal overflow without clipping the visualization.
+- `.table-sm`: Add to `.table` when more rows need to fit; it reduces cell padding without shrinking text.
+- `.text-end`, `.text-center`, and `.text-nowrap`: Use inside `.table` for numeric/end alignment, centered values, or values that must stay on one line. Numeric cells use tabular figures when end-aligned.
+
+### Text
+
+- `.text-small`: Use for the smallest host-scaled secondary chart labels and annotations, never below 11px or for essential content.
+- `.text-muted`: Use for secondary units, captions, timestamps, and context, never essential values or labels.
+- `.text-destructive`: Use only for error or validation text the user needs to notice or act on.
+- `<code>`: Use for inline commands, file names, symbols, or short references; put multiline code in `<pre><code>`.
+- `.sr-only`: Use for visually hidden accessible text.
+
+## Charts
+
+- Prefer inline SVG for simple charts and version-pinned approved-CDN libraries when native interaction, scales, legends, or layout materially improve the result.
+- Resolve theme colors before passing them to canvas or chart APIs that cannot parse CSS variables or `light-dark(...)`; redraw when the theme changes.
+- Use a tooltip unless it would distract from a simple, directly labeled chart. Keep chart-library tooltips and grouped legend interactions native; never replace them with a custom one-point tooltip. For SVG, attach `data-tooltip` directly to the real pointer-accessible mark and include its label, value, and units; the sandbox handles themed positioning, keyboard focus, and touch.
+- Animate transitions between chart states so lines and marks move to their new values, resampling paths when point counts differ. Do not animate initial appearance or use fade-only effects; never loop motion, and honor `prefers-reduced-motion`.
+- Scope SVG styles to the chart class. Never target every `svg` in a container that also contains Lucide icons.
+- Include labeled axes, units, and directly labeled important values. Give every chart, SVG, canvas, and widget a concise screen-reader summary using a role and accessible name or description, SVG `<title>`/`<desc>`, fallback text, or an `.sr-only` heading or description.
+- Reserve space for the longest formatted label at every supported width. Axis ticks are secondary and may use `.text-small` when space is tight. Never overlap or clip text against marks, axes, legends, labels, or edges; move or reduce labels rather than squeeze them.
+- Add a legend only when multiple series cannot be labeled directly.
+- Pair color with shape or text so meaning never depends on color alone.
+
+## Icons and mockups
+
+- Use the sandbox-provided global `lucide`. Add an icon name with `data-lucide`:
+
+  ```html
+  <i data-lucide="search" aria-hidden="true"></i>
+  ```
+
+- Never author inline icon SVG or icon paths. Use only supplied Lucide names; the sandbox replaces each placeholder with a host-sized `currentColor` SVG. Reserve authored inline SVG for charts and data marks.
+- Mark decorative icons `aria-hidden="true"`. Put action icons inside labeled controls; use a visible label or `aria-label` for icon-only actions.
+- Let the sandbox initialize static icons after the fragment without blocking first render. After adding icons dynamically, use `lucide.createIcons({ attrs: { width: 16, height: 16 } })`.
+- Never load Lucide or another icon library from the network.
+- Use visibly labeled buttons and inputs for small interactions. Keep all presentation-only interaction local to the fragment and make the first render useful before input changes.
+- Use semantic controls, realistic spacing, and restrained chrome for mockups. Never fake product screenshots when inspectable UI is needed.
+
+## CCbuddy host compatibility
+
+- Emit inline references only when the Desktop context advertises Gen UI and supplies its session output directory; otherwise return an ordinary HTML artifact. Paths must be absolute on the executor, inside that session directory, with no symlinks or parent traversal. The host renders completed assistant messages only.
+- The frame starts at 240px, follows content height up to 10,000px, and has a host-compensated 5px paint gutter. These are implementation limits, not a target height or a reason to add padding. Secondary annotations are optional; there is no required footer.
+- `window.ccbuddy` exposes widget state, state saving, and follow-up messages. See [API](references/api.md) for acknowledgement, cancellation, and Tweak object bindings. The standalone export supplies state fallback, not Agent access.
+- Older text `::visualize{path="..."}` references remain supported for historical replies. Generate the Unicode reference described above for new replies.

+
+`widgetState` is a snapshot or `null`. Saving replaces the whole `{modelContent, privateContent}` object; omitted fields become `null`. Both must be JSON values. The combined serialized size is at most 16 KiB. The host includes only `modelContent` as untrusted data on the next submitted input. No `callTool`, resource reader or full Desktop preload is available. Theme and size synchronize automatically.
+
+## Local design controls
+
+The source contract is [tweak.md](../tweak.md). The example below uses the same API with the CCbuddy bridge.
+
+Render the initial mockup first. Use a separate Tweak group for each editable component and give its root a descriptive `aria-label`. The optional helper binds objects and supplies host controls; it does not render a Tweak.js panel.
+
+```html
+<div id="player" aria-label="Music player">Play</div>
+<style>
+  #player {
+    --player-accent: #7c3aed;
+    padding: 20px;
+    background: light-dark(#f5f3ff, #282235);
+    color: light-dark(#24212d, #f5f3ff);
+  }
+</style>
+<script>
+  const state = { radius: 18, accent: "#7c3aed", playing: true, density: "normal" };
+  const player = document.getElementById("player");
+  function render() {
+    player.style.borderRadius = `${state.radius}px`;
+    player.style.setProperty("--player-accent", state.accent);
+    player.textContent = state.playing ? "Pause" : "Play";
+    player.style.padding = state.density === "compact" ? "12px" : "20px";
+  }
+  render();
+  if (globalThis.Tweak) {
+    const tweaks = new Tweak({ container: player, onChange: render });
+    tweaks.addSlider(state, "radius", { label: "Corner radius", min: 0, max: 40, unit: "px" });
+    tweaks.addColorPicker(state, "accent", { label: "Accent", reference: "--player-accent" });
+    tweaks.addToggle(state, "playing", { label: "Playing" });
+    tweaks.addSelect(state, "density", {
+      label: "Density",
+      options: [
+        { label: "Comfortable", value: "normal" },
+        { label: "Compact", value: "compact" },
+      ],
+    });
+  }
+</script>
+```
+
+- `new Tweak({ container, onChange })` creates a component group; `supported` reports support.
+- `addSlider(object, property, { min, max, step = 1, unit?, label?, reference? })` binds a number. Units label it; values remain numeric.
+- `addColorPicker(object, property, { label?, reference? })` binds a six-digit hex color.
+- `addToggle(object, property, { label?, reference? })` binds a boolean.
+- `addSelect(object, property, { options, label?, reference? })` binds a string; options may be strings or `{label,value}`.
+- Up to 12 controls per group and 12 options per select. A reference is a token/property hint using letters, digits, `_ - . / : @ $ #` and no spaces.
+- The bound object changes before `onChange`, including reset and temporary original preview. Keep the callback a deterministic local render; do not perform network writes or send messages there. Preserve the registered root, changing its styles or descendants.
+- The host combines groups, owns the launcher/panel, reset, original preview, and explicit submit. Changes alone never send an Agent message. Call `dispose()` if permanently removing a component before page cleanup.
+
+Only the object-binding signature is supported. Keep the component container connected; removing it disposes its registration and previews. A page may register up to 64 components and each component up to 12 controls. Registrations are acknowledged in order before their previews become active.

+# UI mockup variants and design controls
+
+## Variant carousel
+
+- Show one complete design at a time. Make the named designs meaningfully different in layout and interaction, beyond recoloring one design. Keep side-by-side layouts when the user explicitly asks for simultaneous comparison.
+- Use one `.viz-carousel` root with an `aria-label` and one direct child per design, each labeled with a unique, short `data-variant` name. Start with only the first design visible and mark the others `hidden`.
+- The runtime supplies previous/next buttons, a count, and a named picker at the bottom center. It switches designs without replacing their DOM, so local interactions and state survive. Do not generate carousel JavaScript, navigation markup, or CSS.
+- Keep the carousel outside product-scoped mockup styles. The carousel is an exception to the mockup utility rule; use product-specific styles inside each variant. The carousel reserves bottom space for its controls. Give every variant the same responsive stage height, sized for the tallest design, so navigation stays in place when switching. At narrow widths, increase the shared stage height or reflow the product content so nothing clips.
+- Use stable, descriptive names that can be referenced in feedback. Do not submit feedback on navigation or start animation or audio when a variant becomes visible.
+- For another language, set `data-previous-label` and `data-next-label` on the root. The count and names update automatically. Navigation stays local; it does not persist a selection or submit it to the model.
+
+```html
+<div class="viz-carousel" aria-label="Music player designs">
+  <section data-variant="Minimal" aria-label="Minimal music player">
+    <!-- Complete interactive player with product-specific styles -->
+  </section>
+  <section data-variant="Editorial" aria-label="Editorial music player" hidden>
+    <!-- A distinct design, with its own controls and state -->
+  </section>
+  <section data-variant="Studio" aria-label="Studio music player" hidden>
+    <!-- A third design -->
+  </section>
+</div>
+```
+
+## Design controls
+
+The app supplies a small `Tweak` object-binding helper. It sends controls to the host and applies returned values to your bound objects; it does not render the Tweak.js panel. Do not import Tweak.js or generate host API wiring, callback IDs, DOM event listeners, theme synchronization, or a controls launcher.
+
+Render the mock's initial state first. Guard the optional helper so the same HTML still works in hosts and standalone renderers without design controls:
+
+```js
+const state = { radius: 18, accent: "#7c3aed", playing: true };
+const player = document.getElementById("music-player");
+
+function render() {
+  player.style.borderRadius = `${state.radius}px`;
+  player.style.setProperty("--player-accent", state.accent);
+  player.querySelector("button").textContent = state.playing ? "Pause" : "Play";
+}
+render();
+
+if (globalThis.Tweak) {
+  const tweak = new Tweak({ container: player, onChange: render });
+  tweak.addSlider(state, "radius", { label: "Corner radius", min: 0, max: 40, unit: "px" });
+  tweak.addColorPicker(state, "accent", { label: "Accent", reference: "--player-accent" });
+  tweak.addToggle(state, "playing", { label: "Playing" });
+}
+```
+
+Give each component a descriptive `aria-label` for its group heading. Use a separate `Tweak` instance for each independently editable element; the host combines the groups in one panel. Keep the registered element alive and update its styles or descendants in `onChange` rather than replacing it.
+
+For a variant carousel, bind `Tweak` to the independently editable components inside each variant, with matching descriptive `aria-label` values. Do not also add a Tweak select for the active variant.
+
+- `addSlider(object, property, { min, max, step = 1, unit?, label?, reference? })` binds a number. `unit` is display context in the label, not part of the numeric value.
+- `addColorPicker(object, property, { label?, reference? })` binds a hex color string.
+- `addToggle(object, property, { label?, reference? })` binds a boolean.
+- `addSelect(object, property, { options, label?, reference? })` binds a string. Options can be strings or `{ label, value }` objects.
+
+The helper updates the bound property before calling `onChange`, including reset and temporary original preview. Make `onChange` a deterministic local render function, not a network write or irreversible action. Initial values are the current mock state. Use at most 12 controls per component and 12 options per select. Optional `reference` hints identify a token or state property, for example `--player-accent` or `player.radius`; use no spaces or punctuation other than `_ - . / : @ $ #`.
+
+The host owns opening, closing, reset, and submitting changes. Missing annotation support is inert (`tweak.supported` is false). Page cleanup is automatic; call `tweak.dispose()` only if removing the component before navigation.

+# Calendar
+
+Use the bundled `<viz-calendar>` for a day schedule when this composition fits. Its Shadow DOM owns layout, colors and typography, including overlap lanes and event durations. The element applies the shared `.widget` class and a 12px content inset automatically; do not wrap it in another card or add another inset. Its flat surface uses the host card radius, corner shape and thin outline; event colors use the environment palette. Event labels stay 14px in both short and full-day views; longer ranges compact the spacing, not the type. Short blocks show only the title instead of stretching the whole schedule for secondary text. Hover, focus or tap an event to see its full title, time and detail in the shared tooltip. Use custom HTML for a different calendar view. [Complete static example](../examples/calendar.html).
+
+## JavaScript data
+
+Assign an array directly to `calendar.events`. Configure it before appending so the first render includes the events. The host registers the component synchronously before running the fragment; use the literal `viz-calendar` name in HTML or JavaScript so it can include the runtime. No import, initialization or custom CSS is needed.
+
+```html
+<div id="calendar-host"></div>
+<script>
+  {
+    const root = document.getElementById("calendar-host");
+    const calendar = document.createElement("viz-calendar");
+    calendar.setAttribute("date", "2026-09-08");
+    calendar.setAttribute("start", "11:00");
+    calendar.setAttribute("end", "14:00");
+    calendar.events = [
+      { title: "Standup", start: "12:00", end: "12:30" },
+      { title: "Email block", start: "12:00", end: "12:30", tone: "green" },
+      { title: "Design sync", start: "13:00", end: "14:00", video: true },
+    ];
+    root.append(calendar);
+  }
+</script>
+```
+
+Keep the element reference for updates: `calendar.events = updatedEvents` redraws synchronously. Replace the array to update; changing an array or event in place does not trigger a render. Text is escaped by the renderer, so JavaScript values need no HTML-attribute escaping.
+
+The property takes precedence over the `events` attribute until assigned `undefined`, which restores attribute input. Assign `[]` to clear the schedule. Property data is not reflected into HTML attributes; keep it separately when saving or restoring the fragment. Properties assigned before registration are picked up on upgrade.
+
+## Event selection
+
+Add `interactive` when the fragment handles event selection. Each event becomes a native button, supporting click, Enter and Space. Listen on the calendar or an ancestor:
+
+```js
+const selection = document.createElement("output");
+selection.setAttribute("aria-live", "polite");
+calendar.after(selection);
+calendar.setAttribute("interactive", "");
+calendar.addEventListener("eventselect", ({ detail: { event } }) => {
+  // Update a local detail view using the selected source event.
+  selection.textContent = `${event.title} · ${event.start}-${event.end}`;
+});
+```
+
+`eventselect` bubbles across Shadow DOM. Its `detail.event` is the original supplied object, including any caller-owned ID; `detail.index` is its position in the input array, before sorting or clipping. Without `interactive`, event buttons expose their details without emitting a selection. Selection does not change calendar data or contact a service. Interactive events use the host's cursor preference and a subtle hover tint.
+
+## Switching days
+
+The component renders one day and has no built-in tabs. Add the shared [Tabs](../SKILL.md#tabs) outside it only when there are two or more supplied days to switch between; omit tabs for a single day. On selection, assign the chosen day's `date` and `events` to the same element. Do not invent more days to fill a tab bar.
+
+## Static HTML
+
+For a fixed snapshot, the JSON attribute remains sufficient:
+
+```html
+<viz-calendar
+  date="2026-09-08"
+  start="11:00"
+  end="14:00"
+  now="11:50"
+  events='[{"title":"Standup","start":"12:00","end":"12:30"},{"title":"Design sync","start":"13:00","end":"14:00","video":true}]'
+>
+</viz-calendar>
+```
+
+Escape HTML attribute content, including apostrophes as `&#39;` inside single-quoted JSON. Attribute changes redraw synchronously when no JavaScript property overrides the events.
+
+## Configuration
+
+| Attribute      | Meaning                                                           |

+| `now`          | Optional current-time marker. Supply only when verified.          |
+| `time-zone`    | Optional short zone label; does not convert timestamps.           |
+| `lang`         | Date-formatting locale; defaults to the host language.            |
+| `empty-label`  | Empty-state text; defaults to "No events".                        |
+| `interactive`  | Boolean attribute; enables event buttons that emit `eventselect`. |
+
+Use the three hours around the next event for a brief check-in or the requested range for a full-day view. Times are local wall-clock `HH:MM`, with `24:00` allowed as an end. Convert source timestamps to the requested date and zone before passing them in.
+
+Each event requires `title`, `start` and `end`. Optional fields are `tone` (`blue`, `green`, `red`, `orange`, `purple`, `yellow`), `detail` (short secondary text) and `video` (a boolean that shows a video-call icon). Tones use the environment's theme variables, such as `--green`; omitted tones default to blue. Keep a small, consistent palette for source calendars or categories. Supply at most 200 events; events outside the visible window are clipped or omitted. Invalid data produces an inline error that clears when valid data is supplied.
+
+## Rendering and updates
+
+The component builds its styled shadow tree synchronously on connection and updates it synchronously on assignment. An existing declarative shadow root is preserved during upgrade unless JavaScript event data was supplied, in which case that data is rendered.
+
+This is a supplied snapshot. It has no connector, booking, background clock or network access. Refresh data in the host and pass the resulting array to `events`; update `now` separately when needed. Keep extra facts in the surrounding response.

+# MCP tool descriptor refresh
+
+## Product rule
+
+An MCP server's `notifications/tools/list_changed` notification takes effect at
+the next agent turn boundary. Changes to any normalized `McpToolDescriptor`
+field must refresh the runtime registry and invalidate its derived provider
+tool cache, even when the tool name and description are unchanged. This
+includes input schemas, annotations, model/app visibility, tool timeout and
+UI metadata. The existing MCP result-envelope output schema remains unchanged;
+this work does not introduce projection of the server's output schema.
+
+Equivalent descriptor objects with different property insertion order or a
+different tools-list order are a no-op. Arrays within a descriptor retain
+their order because schema arrays can carry positional meaning.
+
+## Owners, interfaces and event order
+
+The MCP adapter owns the normalized descriptors, stale-server markers and
+notification revision exposed by `McpPort.listTools()` and
+`McpPort.toolListRevision()`. Each runtime owns its registered MCP tool names,
+last observed revision and complete descriptor signature. The registry and
+provider cache are projections of that adapter-owned list. No new owner,
+protocol, persistence or cross-module interface is introduced.
+
+```text
+server tools/list_changed
+  -> adapter marks that server stale and increments revision
+  -> next turn: runtime captures revision, then awaits listTools
+  -> adapter returns normalized descriptors
+  -> runtime compares a stable signature of the complete descriptors
+     -> unchanged: record captured revision, preserve registry/cache
+     -> changed: replace MCP registrations, invalidate provider cache
+```
+
+Refresh stays at the existing turn boundary. An unchanged revision, an
+uninitialized runtime or a port without revisions does not trigger a fetch.
+A rejected `listTools` leaves the revision unconsumed so the next boundary can
+retry. Notifications arriving during the fetch remain observable because the
+runtime records the revision captured before the fetch, not a later revision.
+Adapter-level retry semantics and server failure handling are unchanged.
+
+Desktop continuous delivery and mobile replayable delivery use the same
+runtime registry and turn admission boundary; this change adds no stream,
+snapshot, replay, owner/lease or remote attachment behavior. Existing workspace
+identity and remote-session routing remain in the original tool registration
+and invocation paths. There is no data migration.
+
+## Acceptance
+
+1. With unchanged names/descriptions, independently changing input schema,
+   annotations, visibility, timeout or UI metadata replaces the registered
+   entry and invalidates the provider cache. Provider contracts and UI/tool
+   metadata expose the new values; model/app visibility works in both directions.
+2. Complete descriptor changes, including optional fields, update the signature.
+   Identical lists, reordered tools and recursively reordered object keys do
+   not replace entries or invalidate caches. Ordered schema-array changes do.
+3. Unchanged or unavailable revisions and notifications before the next turn
+   boundary leave current entries intact. Rejected `McpPort.listTools()` calls
+   retry at the next boundary. A new port revision observed during a pending
+   `McpPort.listTools()` call triggers another port call at the next boundary;
+   this does not guarantee adapter-internal failure retries or stale-marker
+   handling.
+4. Existing allow/deny filtering, official-CUA authority and plugin ownership
+   continue through the existing `registerMcpTools` path.

+# Plugin UI and Gen UI
+
+## Product rule
+
+CCbuddy Desktop can show interactive pages from two sources. They use
+different protocols and their APIs must not be mixed.
+
+**Plugin UI (MCP Apps).** An installed and enabled plugin whose MCP server
+publishes `ui://` HTML resources may render them as tool-result cards or as
+session side-pane surfaces declared in the manifest's `ui.surfaces`. Pages talk
+to the host through the official `@modelcontextprotocol/ext-apps` SDK;
+business data stays with the plugin's MCP server. Page-initiated tool calls
+reuse the existing permission decision and approval flow and never create
+transcript rows. Sampling from a page uses the model service the user
+configured for the current task. There is no upstream account, official MCP
+identity header or hosted model behind any of this: the protocol entrypoint
+keeps the MCP elicitation and notification ports and does not wire the
+upstream official-MCP auth block.
+
+**Gen UI.** The Agent may generate an HTML page for the current answer. The
+desktop hands the Agent a per-session output directory under the application
+data root (`~/.ccbuddy/v2/visualizations/<scope hash>`); pages are never
+written into the workspace, and the path helper rejects an output root inside
+the workspace. Page state (`widgetState`) lives under the same root
+(`gen-ui-state`), scoped by workspace identity and session; only
+`modelContent` re-enters the model context. A follow-up message is sent only
+after an explicit user action.
+
+Interactive pages are a Desktop local-workspace capability. Web, mobile remote
+control and remote workspaces keep ordinary MCP tool records and do not claim
+these surfaces.
+
+Pages run in a separate Electron sandbox (`persist:plugin-sandbox-v2-…`
+partitions derived from the trusted plugin identity) with a per-resource CSP;
+a plugin may only relax `unsafeEval` / `wasmUnsafeEval` through
+`_meta["ccbuddy/csp"]`. Gen UI pages may load static assets only from the
+fixed allowlist in `packages/shared/src/gen-ui/contract.ts` (public script
+CDNs and font hosts). That allowlist is a page-authoring allowance, not an
+application update or asset source: the runtime kit (`visualize.css`,
+`visualize.html`, `calendar.js`, the tweak runtime, d3, lucide, floating-ui)
+ships inside the bundled `visualize` plugin with SHA-256 values pinned in
+`runtime-manifest.json` and `vendor/manifest.json`, and the desktop copies it
+into the sandbox at build time. "Clear All Data" also clears the plugin
+sandbox browser storage.
+
+The bundled official plugin `visualize` is registered in
+`official-plugin-definitions.ts` like the other official plugins: local
+default icon, no CDN reference, marketplace `ccbuddy-plugins-official`.
+Protocol methods, context keys, events, environment names and DOM globals use
+the CCbuddy name (`ccbuddy/gen-ui/*`, `ccbuddy:set_globals`,
+`window.ccbuddy`, `window.ccbuddyPluginSandbox`, `CCBUDDY_GEN_UI_*`).
+
+This capability is ported from the upstream foundation project's UI-plugin
+work on top of the current base, with the identity rules of
+`product-branding.md` and the data rules of `product-data-isolation.md`
+applied. The developer guide is `docs/ui-plugin.md`.
+
+## Owners and event order
+
+```text
+manifest ui.surfaces / tool _meta.ui -> agent mcp-ui (bootstrap) -> plugin-ui-bridge (services)
+  -> plugin-ui host (ui) -> pluginSandbox guest partition (desktop)
+page callServerTool / sampling / app tools -> plugin-ui-bridge -> agent session
+  -> existing permission + approval -> plugin MCP server / configured model service
+agent answer + generated page -> ~/.ccbuddy/v2/visualizations/<scope> -> gen-ui host -> sandbox page
+page setWidgetState -> ~/.ccbuddy/v2/gen-ui-state ; sendFollowUpMessage -> composer (user confirms)
+```
+
+Module boundaries are owned by `architecture-policy.yaml` (`mcp-apps-protocol`,
+`mcp-ui`, `plugin-ui-bridge`, `plugin-sandbox`, `plugin-ui`,
+`gen-ui-protocol`, `gen-ui-service`, `gen-ui`) and each module's
+`CONTRACT.md`. `packages/services/src/paths.ts` still owns the data root; the
+Gen UI service derives its output and state roots from it and the desktop
+passes the output root to the Agent through `CCBUDDY_GEN_UI_OUTPUT_ROOT`.
+
+The renderer's plugin row derivations and manual disclosure pins have one
+session cache owner (`pluginUiInstanceStore`). Both use
+`buildPluginUiSessionKey` (workspace identity, with local path fallback, plus
+session ID). Mounted timelines hold reference-counted leases; their entries
+cannot be evicted. The owner retains at most 30 additional inactive sessions,
+ordered by the latest write, mount or last release. Eviction removes the
+derivation and pins together and notifies subscribers. Reads are pure.
+Returning to a retained session keeps its pins; returning after eviction
+rederives the row policy and uses default disclosure. No state is persisted.
+Task removal by the page owner requests clearing the cached derivation and
+pins. With mounted timelines, the owner marks the entry for clearing and
+preserves its current data until the last lease releases; unchanged rows must
+not lose their published policy. The last release removes the entry directly
+instead of retaining it in the LRU. With no leases, clearing is immediate.
+Repeated clear requests and lease releases are idempotent. Timeline release and
+cache eviction never dispose a sandbox, cancel a page call or release a page
+lease; live pages and side panes keep their existing owner and limits.
+
+```text
+timeline mount -> scoped view-cache lease -> derive rows / change pins
+timeline unmount -> release matching lease -> last release enters inactive LRU
+page task removed -> mark pending clear -> last release removes derivation + pins -> notify
+inactive capacity exceeded / clear without leases -> remove derivation + pins -> notify
+sandbox page owner -> independently retain inline / side-pane guest and calls
+```
+
+Duplicate mounts each own a lease. Release is idempotent; a release captured
+before explicit removal cannot alter a later entry for the same session.
+This is renderer-local cache retention and does not change desktop continuous
+or mobile replayable delivery.
+
+## Acceptance
+
+1. `pnpm typecheck`, the CLI workspace typecheck, `pnpm lint`,
+   `pnpm fmt:check` and `pnpm architecture:check` pass.
+2. The mcp-apps, plugin-ui, plugin-ui-bridge, pluginSandbox and gen-ui tests
+   under `packages/{shared,services,ui,desktop,client}` and
+   `apps/ccbuddy-cli/packages/{bootstrap,core,adapters}` pass, including
+   `gen-ui-runtime-assets.test.ts` (pinned asset hashes) and
+   `gen-ui-vendor-export.test.py`.
+3. `node packages/desktop/scripts/gen-ui-e2e.mjs` (after a renderer build) and
+   `node packages/desktop/scripts/mcp-apps-host-e2e.mjs` drive the Electron
+   sandbox with the current source.
+4. Gen UI output and state resolve below `~/.ccbuddy/v2`; a workspace path
+   as output root is rejected. No page can reach Node, arbitrary files or
+   another plugin's MCP server.
+5. No string, protocol key, DOM global or file name introduced by this
+   feature carries the upstream product name, and the plugin sandbox storage
+   is removed by Clear All Data.
+6. View-cache tests cover 30 inactive sessions plus mounted sessions, dual
+   mounts and repeated/stale releases, workspace isolation, paired pin eviction
+   and subscriber notifications. The existing Electron retention fixture checks
+   that switching through more than 30 timelines releases cached view state
+   without destroying a retained guest, and revisiting restores row policy.

+# UI Plugin 与 Gen UI：能力、页面 API 与宿主调试
+
+产品规则与验收见 [规范](specs/plugin-ui-and-gen-ui.md)。本文面向插件作者和宿主联调。
+
+## UI Plugin 能做什么
+
+UI Plugin 给普通插件增加可交互页面。Agent 调用工具创建或修改内容，用户直接操作画布、表单、文件列表，再把选区或操作结果交回对话。页面通过 MCP Apps 与宿主通信，业务数据由插件的 MCP 服务管理。注册、安装、启用和更新沿用普通插件流程；页面使用官方 `@modelcontextprotocol/ext-apps`（宿主锁定 `2.0.0`），不需要单独的 SDK。
+
+| 能力               | 用户看到的效果                               | 开发入口                                         |
+| ------------------ | -------------------------------------------- | ------------------------------------------------ |
+| 工具结果带交互页面 | 生成画板、展示图表、填写表单                 | MCP 工具 `_meta.ui.resourceUri` + HTML 资源      |
+| 会话侧栏面板       | 手动打开编辑器，后续工具继续操作同一份文档   | 清单 `ui.surfaces`，工具 `_meta.ui.surface`      |
+| 页面调用插件服务   | 点击按钮刷新数据、保存文档、执行操作         | `app.callServerTool()`                           |
+| 页面与主对话协作   | 引用选区，或由用户点击发送下一条消息         | `updateModelContext()` / `sendMessage()`         |
+| App 内模型调用     | 回答留在插件自己的界面                       | `createSamplingMessage()`                        |
+| 模型调用页面工具   | 操作只有活页面才拥有的编辑器状态             | `registerTool()` 或 `onlisttools` + `oncalltool` |
+| 页面状态与资源更新 | 切换位置保留页面，重建恢复视图，订阅服务变化 | 活页面保留、widgetState、资源订阅                |
+
+交互页面只用于 **CCbuddy Desktop 的本地工作区**。Web、手机和远程工作区保留普通 MCP 工具记录。插件页面与 Gen UI 的加载和通信协议不同，不能混用两者的 API。
+
+## Gen UI：按需生成可交互的回答
+
+Gen UI 让 Agent 针对当前问题生成 HTML / JavaScript 页面，直接嵌入对话：拖动滑块、切换条件、勾选项目，观察结果，再带着当前参数继续提问。页面按需生成，不需要先创建和安装插件。内置的 `visualize` 插件提供作者指引、样式和受限的 `window.ccbuddy` 桥；Agent 生成交互视图前会先加载这个 skill。
+
+| 能力       | 当前行为                                                                                   |
+| ---------- | ------------------------------------------------------------------------------------------ |
+| 对话内交互 | 页面随回答完成后展示，可包含图表、表单、模拟器和轻量原型                                   |
+| 展开与分享 | 可以展开预览、收起，并复制当前界面为图片；展开和收起保留同一个活页面                       |
+| 状态与追问 | 页面可保存控件状态，并在用户触发后发送后续问题；仅调整控件或保存状态不会自动启动 Agent     |
+| Tweak 调整 | 页面注册控件后，宿主提供滑块、颜色、开关和选项等调整入口，支持重置、原始效果预览和明确提交 |
+
+生成页面使用宿主注入的接口：
+
+| 接口                                                              | 用途                                                                                  |
+| ----------------------------------------------------------------- | ------------------------------------------------------------------------------------- |
+| `window.ccbuddy.widgetState`                                      | 读取已保存的页面状态，初始值可能为 `null`                                             |
+| `window.ccbuddy.setWidgetState({ modelContent, privateContent })` | 替换整个 JSON 状态快照，合计不超过 16 KiB；只有 `modelContent` 会进入下一轮模型上下文 |
+| `window.ccbuddy.sendFollowUpMessage({ prompt, title })`           | 发送后续问题，`title` 可选；没有有效用户操作时需要确认，失效或只读会话不能发送        |
+| `ccbuddy:set_globals`                                             | 监听状态或主题更新，从事件的 `detail.globals` 读取新值                                |
+
+桌面端向 Agent 提供当前会话的专用输出目录（`~/.ccbuddy/v2/visualizations/<scope>`）。生成的 HTML 保存在该目录，由宿主加载，不写入项目工作区；页面状态按工作区和会话隔离。Gen UI 页面不提供 `callTool`、MCP 资源读取、Node 或任意文件访问；需要插件服务执行操作时使用 UI Plugin。
+
+### Gen UI 与 UI Plugin 怎么选
+
+| 对比项   | Gen UI                                           | UI Plugin                                           |
+| -------- | ------------------------------------------------ | --------------------------------------------------- |
+| 来源     | Agent 围绕当前问题即时生成页面                   | 开发者维护和发布插件，用户安装、启用                |
+| 适合什么 | 概念讲解、交互图表、模拟器、临时计算器和界面原型 | 持续使用的编辑器、文件工具和带业务数据的应用        |
+| 页面能力 | Gen UI 状态、追问与 Tweak 接口                   | MCP Apps API、插件 MCP 工具与资源，遵循宿主支持范围 |
+| 数据归属 | 宿主管理生成文件和会话页面状态                   | 插件服务管理业务文件或数据库，页面管理视图          |
+
+实现与页面示例：[Gen UI 契约](../packages/ui/src/gen-ui/CONTRACT.md)、[页面 API 示例](../apps/ccbuddy-cli/packages/visualize-plugin/skills/visualize/references/api.md)、[Tweak 指南](../apps/ccbuddy-cli/packages/visualize-plugin/skills/visualize/tweak.md)。
+
+## 给自己的插件接入 UI
+
+沿用普通插件的安装目录与市场条目；需要编译的源码包声明自己的 `build`，额外资源使用可选 `stage`。下面是安装清单 `.ccbuddy-plugin/plugin.json` 的最小页面示例：
+
+```json
+{
+  "name": "my-panel",
+  "version": "0.1.0",
+  "description": "我的交互面板",
+  "mcpServers": {
+    "app": {
+      "type": "stdio",
+      "command": "node",
+      "args": ["${CCBUDDY_PLUGIN_ROOT}/dist/server.mjs"],
+      "cwd": "${CCBUDDY_PROJECT_DIR}",
+      "env": {
+        "CCBUDDY_WORKSPACE_ROOT": "${CCBUDDY_PROJECT_DIR}",
+        "CCBUDDY_PLUGIN_DATA": "${CCBUDDY_PLUGIN_DATA}"
+      }
+    }
+  },
+  "ui": {
+    "surfaces": [
+      {
+        "id": "editor",
+        "title": { "en": "Editor", "zh-CN": "编辑器" },
+        "server": "app",
+        "resourceUri": "ui://my-panel/editor.html",
+        "availability": "session"
+      }
+    ]
+  }
+}
+```
+
+服务端需要实际注册 `ui://my-panel/editor.html` 资源并返回 `text/html;profile=mcp-app`。让工具结果使用该面板时，在工具定义中设置 `_meta.ui.resourceUri` 和 `_meta.ui.surface: "editor"`；`_meta.ui.visibility: ["model", "app"]` 允许模型与页面调用，仅页面工具使用 `["app"]`。`ui.surfaces` 可省略，此时仍可通过工具元数据提供内联页面。
+
+插件文件使用 `${CCBUDDY_PLUGIN_ROOT}` 定位，工作区文件操作使用 `${CCBUDDY_PROJECT_DIR}`，持久数据使用 `${CCBUDDY_PLUGIN_DATA}`。用户配置通过清单 `userConfig` 定义，并在服务配置里用 `${user_config.<key>}` 引用。页面通过服务执行文件操作，不直接访问主应用源码或 Node API。
+
+## 页面 API 速查
+
+以当前宿主实现和锁定的 SDK 类型为准。先注册事件，再 `connect()`；连接后读取 `getHostCapabilities()`，按返回的能力启用功能。
+
+### 官方 MCP Apps API
+
+| API / 事件                                                      | 用途                                 | CCbuddy 行为与注意事项                                                                        |
+| --------------------------------------------------------------- | ------------------------------------ | --------------------------------------------------------------------------------------------- |
+| `new App(info, capabilities, options)`、`connect()`             | 创建页面连接并完成握手               | 每个活页面只建一个 App；不要同时访问会触发另一连接的 `window.ccbuddy`                         |
+| `getHostVersion()`、`getHostCapabilities()`、`getHostContext()` | 读取宿主、能力、主题、语言和展示模式 | 在连接完成后使用；不要只按宿主版本号猜能力                                                    |
+| `ontoolinput`、`ontoolresult`、`ontoolcancelled`                | 接收完整输入、结果和取消             | 大 UI 延迟加载时，保留初始结果再交给 UI，避免丢通知                                           |
+| `onhostcontextchanged`                                          | 响应主题、语言、尺寸或模式变化       | 更新显示；不要因此重复执行业务操作                                                            |
+| `callServerTool({ name, arguments }, options)`                  | 调用当前插件服务的工具               | 沿用 Agent 的权限和审批；`options.signal` 可取消；返回真实 `CallToolResult`                   |
+| `readServerResource({ uri })`                                   | 读取当前服务的资源                   | 返回 MCP `contents`；二进制是 base64；不能用它访问其他插件或任意本地文件                      |
+| `listServerResources({ cursor })`                               | 分页列出服务资源                     | 资源模板列表用后表中的 `resources/templates/list` 请求                                        |
+| `sendMessage({ role: "user", content })`                        | 发出主对话后续消息                   | 需要 `message` 能力；有用户手势时发送，无手势时进入确认流程                                   |
+| `updateModelContext({ content, structuredContent })`            | 给下一轮对话附加选区等上下文         | 需要 `updateModelContext` 能力；在输入区可见、可删，不立即发消息，不是持久存储                |
+| `createSamplingMessage(params, { signal })`                     | App 内调用当前任务模型               | 需要 `sampling` 能力；支持文本与符合限制的图片输入，返回文本；对话历史由 App 提供             |
+| `registerTool(name, config, handler)`                           | 页面提供可被模型调用的工具           | 握手前登记；声明 App 的 `tools` 能力；随活页面登记/撤销并遵守既有审批                         |
+| `onlisttools`、`oncalltool`、`sendToolListChanged()`            | 手动管理页面工具目录                 | 另一种页面工具实现方式；取消信号在回调 `extra.mcpReq?.signal` 中                              |
+| `requestDisplayMode({ mode })`                                  | 请求切换展示位置                     | `inline` 为内联，`fullscreen` 为侧栏；以返回模式为准；`pip` 当前保持原模式                    |
+| `sendSizeChanged({ height })`                                   | 报告内容高度                         | 可用 SDK 自动测量；手动测量内容容器，避免把视口高度反馈给宿主                                 |
+| `openLink({ url })`                                             | 通过宿主打开外链                     | 仅允许 `http:` / `https:`                                                                     |
+| `downloadFile({ contents })`                                    | 调用原生保存对话框                   | 需要 `downloadFile` 能力；支持嵌入资源或当前服务的资源链接；取消/写入失败返回 `isError: true` |
+| `sendLog({ level, data })`                                      | 发送可观察的页面诊断                 | 不向 stdio 服务的 stdout 写调试日志；不要记录密钥或用户内容                                   |
+| `onteardown`                                                    | 释放页面监听器等资源                 | 宿主做有时限的 teardown，不应把唯一保存操作留到此时                                           |
+| `requestTeardown()`                                             | 请求宿主释放页面                     | 当前只记录请求；实际生命周期跟随卡片/面板，不能把它当关闭按钮                                 |
+
+Sampling 使用接纳请求时的任务模型（用户自行配置的模型服务），不读取主聊天历史；只有 App 明确传入的历史进入请求。当前不接受 `temperature`、`tools`、原生 audio 等未实现参数，`includeContext` 只支持 `none`。回答和取消不会被自动追加为主对话回合。
+
+### CCbuddy 扩展与低层 MCP 请求
+
+`app.request()` 是官方 App 的低层接口，结果用 `@modelcontextprotocol/core` 的对应 schema 校验。
+
+| 接口 / 字段  | 调用或声明方式                                                                            | 适用范围                                                                                                                |
+| ------------ | ----------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------- |
+| 会话视图状态 | `ui/set-widget-state`，参数 `{ widgetState }`，结果 `EmptyResultSchema`                   | 先检查 `experimental["ccbuddy/widgetState"]`；初值来自 hostContext 同名键；仅宿主内存，会话内重建可恢复，应用重启不保证 |
+| 资源模板列表 | `resources/templates/list`，结果 `ListResourceTemplatesResultSchema`                      | 当前服务的 MCP 模板目录；不要假定 App 存在 `listServerResourceTemplates()` 便捷方法                                     |
+| 资源订阅     | `resources/subscribe` / `resources/unsubscribe`，参数 `{ uri }`，结果 `EmptyResultSchema` | 先检查 `experimental["ccbuddy/resourceSubscribe"]`；服务端也须支持订阅                                                  |
+| 资源变更通知 | `notifications/resources/updated` / `notifications/resources/list_changed`                | 先用 `setNotificationHandler()` 注册处理器；收到 URI 后自行重新读取资源                                                 |
+| 当前侧栏面板 | `app.getHostCapabilities()?.experimental?.["ccbuddy/surface"]` 返回 `{ id }`              | 清单 `ui.surfaces[].id` 与工具 `_meta.ui.surface` 保持一致                                                              |
+| CSP 放宽     | 资源 `_meta["ccbuddy/csp"]` 中 `unsafeEval`、`wasmUnsafeEval`                             | 检查 `experimental["ccbuddy/csp"]` 返回的支持标记；不等于获得文件或网络权限                                             |
+
+### 现有 `window.ccbuddy` 页面
+
+已有兼容页面可以继续使用以下别名；新页面优先使用官方 App，两种连接方式选一种即可。
+
+| 类别           | 可用成员                                                                                                                             |
+| -------------- | ------------------------------------------------------------------------------------------------------------------------------------ |
+| 连接与观察     | `ready()`、`subscribe(listener)`，后者返回取消订阅函数                                                                               |
+| 输入与宿主信息 | `toolInput`、`toolOutput`、`toolResponseMetadata`、`toolCancelled`、`hostInfo`、`hostCapabilities`、`hostContext`、`protocolVersion` |
+| 展示信息       | `theme`、`locale`、`displayMode`、`maxHeight`、`safeArea`、`userAgent`                                                               |
+| 工具与资源     | `callTool(name, args)`、`readResource(uri)`、`listResources()`、`listResourceTemplates()`                                            |
+| 资源订阅       | `subscribeResource(uri)`、`unsubscribeResource(uri)`、`onResourceUpdated(listener)`、`onResourceListChanged(listener)`               |
+| 会话视图状态   | `widgetState`、`setWidgetState(state)`                                                                                               |
+| 对话协作       | `sendFollowUpMessage({ prompt, structuredContent })`、`updateModelContext({ content, structuredContent })`                           |
+| 展示与文件     | `requestDisplayMode({ mode })`、`notifyIntrinsicHeight(height)`、`openExternal({ href })`、`downloadFile(contents)`                  |
+
+别名没有 sampling 或页面工具的便捷接口；需要这些能力时使用官方 App。`openExternal` 的参数叫 `href`，官方 `openLink` 的参数叫 `url`，不要混用。
+

+
+## 平台、数据与能力边界
+
+| 数据 / 能力                      | 应放在哪里或如何使用                                                                       |
+| -------------------------------- | ------------------------------------------------------------------------------------------ |
+| 业务文档、清理计划、场景版本     | 插件服务持有；文件或数据库写入插件数据目录，按业务规则确认和恢复                           |
+| 当前活页面输入、滚动和运行中请求 | 同一活页面切内联/侧栏时保留；不重复连接或重发请求                                          |
+| `widgetState`                    | 临时界面快照；重建、手动重试与进程重启的语义不同，不能用来承诺永久保存                     |
+| localStorage / IndexedDB         | 稳定来源下的浏览器存储，可跨进程；按插件身份/工作区隔离，"清除所有数据"会一并清掉          |
+| 网络、字体、WASM、脚本           | 优先随包提供；外部访问受资源 CSP 限制，页面没有 Node 或任意文件系统访问权                  |
+| 原生权限                         | camera / microphone / geolocation / clipboardWrite 需资源声明及宿主/系统授权；不是默认可用 |
+
+HTML 资源上限 **16 MiB**，页面资源读取上限 **8 MiB**。初始工具结果限制：`structuredContent` 64 KiB、页面元数据 16 KiB、`content` 32 KiB；超限字段会被省略并标记，页面应从服务重新读取完整数据。尚未实现：纯图片/资源链接的完整消息内容扩展、App 工具双向进度。
+
+## 宿主开发与调试
+
+1. `pnpm dev:desktop` 启动宿主；宿主不会自动注册插件。
+2. 把插件目录做成本地市场后用 CLI 装进同一份配置（`--scope user`），或在桌面 **插件市场 → 新增** 里添加该目录：
+
+   ```sh
+   pnpm ccbuddy plugins marketplace add /path/to/local-marketplace --scope user
+   pnpm ccbuddy plugins install my-panel@<来源名> --scope user
+   pnpm ccbuddy plugins enable my-panel@<来源名> --scope user
+   ```
+
+   修改插件代码后刷新来源并重装：刷新只更新目录，重装才更新代码副本。之后重启桌面实例，在新会话里验证。
+
+3. 验证入口：
+
+   | 层次         | 命令                                                                                                        |
+   | ------------ | ----------------------------------------------------------------------------------------------------------- |
+   | 静态检查     | `pnpm typecheck`、`pnpm lint`、`pnpm fmt:check`、`pnpm architecture:check --changed`                        |
+   | 模块单测     | 根目录 `pnpm exec vitest run <文件>`；`packages/ui` 内的测试在该目录下运行以启用 `@/` 别名                  |
+   | Gen UI 桌面  | `pnpm --dir packages/desktop exec vite build && node packages/desktop/scripts/gen-ui-e2e.mjs`               |
+   | 插件页面桌面 | `node packages/desktop/scripts/mcp-apps-host-e2e.mjs`，可加 `--managed-only` 等模式或 `--reuse-agent-build` |
+
+   桌面 fixture 使用临时 profile 与本地模型 fixture，末尾输出结果目录。
+
+常见问题：
+
+| 现象                       | 先检查                                                                                                                           |
+| -------------------------- | -------------------------------------------------------------------------------------------------------------------------------- |
+| 已登记来源，侧栏仍没有面板 | `plugins list --json` 的安装/启用状态；当前是否是桌面本地工作区；清单的 `ui.surfaces` 是否引用正确 `mcpServers` 键和 `ui://` URI |
+| 修改代码后还是旧页面       | 是否刷新同一来源并重装目标插件；是否仍运行旧实例或旧会话                                                                         |
+| 面板打开但资源失败         | 安装目录是否有 `dist`、离线字体/脚本/WASM；检查 CSP 与资源读取上限                                                               |
+| 握手两次或初始画布为空     | 是否创建了两个 App，或官方 App 与 `window.ccbuddy` 混用；是否在连接前安装事件处理器并保留初始结果                                |
+| 点击"引用"没有立刻发消息   | `updateModelContext` 是给下一轮添加上下文，发消息用 `sendMessage`；检查输入区的插件上下文                                        |
+| sampling 不可用或参数被拒  | 宿主是否声明 `sampling`，当前任务是否可操作，参数是否属于支持子集                                                                |
+| 开发者工具没有页面日志     | 先看应用"帮助 → 开发者工具"里的宿主错误；插件有独立 guest，优先用 `app.sendLog()` 采集自己的日志                                 |
+
+stdio MCP 服务的 stdout 只输出协议消息，调试日志写 stderr。
+
+## 宿主源码导航

+| 排查目标                          | 当前源码入口                                                                                                                                                                                             |

+# plugin-sandbox
+
+Electron Main 适配层，拥有沙箱内容、guest、端口和浏览器分区。Host 登记适配器仅转发请求，不拥有任务事实。
+
+- 登记绑定实际 Host attachment 的 ownerWebContentsId、workspace、session、server、scope 和 Agent 运行凭证；同凭证重复登记返回不可变句柄，不覆写 HTML。sandboxId/initId 仅服务单次 Electron 生命周期。
+- partition 为 `persist:plugin-sandbox-v2-<hash(appIdentity)>`。shell/plugin 两个不同 origin 都由可信 appIdentity 派生；随机 sandboxId 位于资源路径。Chromium 的顶层站点存储键必须稳定，才能使 localStorage/IndexedDB 跨进程恢复。
+- 稳定 origin 不授予资源权限。protocol 校验 origin、实例路径和登记；session 请求检查实际 guest 与目标实例；will-attach-webview 验证 owner、partition 和句柄。重载、销毁与越界导航撤销旧登记。
+- guest 固定 contextIsolation/sandbox/webSecurity，禁用 Node、子框架 Node、webviewTag、plugins、dialogs/popups。MessagePort 在受信 guest 就绪后分发，shell 只转发 JSON-RPC；旧端口不能替代新实例。
+- CSP 使用 default-src none；资源域、连接域、frame 域按声明派生。frame-ancestors 只允许该稳定 shell origin；form-action none。既有 ccbuddy/csp 扩展只放宽 unsafe-eval/wasm-unsafe-eval，不增加浏览器能力。
+- 原生 camera/microphone/geolocation/clipboardWrite 仍按资源声明和既有确认策略授权；绑定实际 guest/frame、owner、运行凭证，异步确认和系统授权返回后再验证。失效页面的确认不能授权替换页面。
+- guest 输入产生 5 秒一次性手势 token。关闭实例同时释放 ports 和实际 guest，partition 持久保留。
+- 上限 64；Main 不抢占其他窗口或刚准备的实例，只清过期且未被 guest pin 的登记。Renderer owner 决定业务回收；容量不足明确报错。
+- 撤销登记先关端口，再由 Main 单次导航 guest 到 about:blank，等待旧插件 frame 移除后 close；IPC dispose 等待同一个停止 Promise。Electron 附着 webview 的 destroyed 可能仅释放包装对象，不是停止页面写入的屏障；插件 beforeunload 不能阻止宿主释放。
+- 清除所有数据先阻止新登记、撤销登记并等待所有 guest 停止（含已在 dispose 的实例），再 clearStorageData/clearCache，覆盖所有新旧 MCP App 分区。停止失败不能继续报告清理成功；flushStorageData 不是完成屏障。平时保留旧 v1 分区，不迁移或自动合并；本模块不访问插件 SQLite 或业务文件。
+
+公开入口 `index.ts` 不暴露 registry/preload/assets。Main 不执行 MCP 权限策略，不保存会话、队列、widgetState；受信 Host 提供已验证 HTML 与实例绑定。
+
+## 实例资源缓存边界
+
+稳定 origin 下所有实例协议响应（包括 shell、alias 与静态脚本）必须使用 `Cache-Control: no-store`。页面存储仍持久化，但响应缓存不得绕过实际 guest 与实例路径校验；真实 Electron 验证必须同时包含冷请求和缓存命中候选。
+
+## Gen UI 随包资源
+
+Gen UI 的 CSS/inner kit 使用 Visualize 插件的同一份固定资源，构建复制到沙箱资源目录，Main 在返回文档时注入；不再在 guest 里执行另一套 Widgets。bridge/Tweak 先于作者片段，inner kit 后于片段。Floating UI、Lucide、D3 的固定 CDN script URL 在 Gen UI partition 请求闸门内映射到同一实例的随包文件，按 `vendor/manifest.json` 精确匹配，不扩大 CSP 或开放任意文件。缺失文件失败，不回退网络；保留现有脚本加载顺序，D3 仍按需。Tweak 的私有回调经现有 Gen UI 方法，不向页面开放 callTool。MCP 文档不加载或重定向这些资源。
+
+资源完整性由 Visualize 的 `assets/runtime-manifest.json` 维护，结构仅为 `files → 文件名 → sha256`，记录当前 CSS、inner kit、calendar 和 Tweak 文件的 SHA-256。桌面资源测试核对实际复制字节与清单；Tweak 注释变更也需要同步哈希。资源名称变更须同时更新 Desktop、CLI SEA、远程预构建、服务端远程部署与插件 seed 校验入口；缺少清单或必需文件仍按现有规则失败，不回退到旧名称。插件的许可入口统一为 `skills/visualize/LICENSE.md`，保留许可限制与第三方依赖声明。
+
+离线依赖继续由 `assets/vendor/manifest.json` 记录固定 npm 版本、包完整性、脚本及许可文件哈希。更新时核对包完整性、提取声明的分发文件和许可证，再更新哈希；Desktop 与独立导出共用这些文件，导出脚本将其嵌入为 data URL。验收覆盖复制资源的哈希、各打包清单路径存在性与许可入口可解析性；交互和会话状态契约不变。
+
+Host preload enables state-preserving atomic moves only for explicitly marked sandbox webviews. The hook is installed before Electron registers its custom element; ordinary detach/disposal and unmarked webviews retain their original behavior. Main copy-image IPC validates sender owner, sandboxId/initId and bounded content/viewport geometry before and after native capture, crops using the actual image scale, and writes the native clipboard. It exposes neither arbitrary guest IDs nor image bytes to untrusted page code.
+
+`contentKind: "gen-ui"` 由桌面 Host 签发独立凭证，不要求 pluginId/serverName，也不能携带原生权限。使用内存分区 `gen-ui-<appIdentity>`；跨重开恢复依赖 Gen UI 服务，不依赖浏览器存储。HTML 外壳包含先于作者脚本执行的已转义状态快照与专用 `gen-ui.js`，不注入旧兼容桥。连接、子框架和表单提交禁用，静态资源限制为 Gen UI 固定域。其余 owner、guest、端口、手势和撤销机制复用本契约。

+# gen-ui-service
+
+Target Workspace Host owns bounded, nonsymlink fragment reads. Desktop Local Host owns persisted
+widget state and issues sandbox registrations with explicit gen-ui provenance. Remote workspace
+content uses the existing remote services route; desktop state uses base services. No new Agent,
+MCP server, content publication journal or accepted command queue is introduced.
+
+The execution Host owns an output root under its application data directory and passes that root
+to the Agent at process startup. Host reads and Agent context use the same scope-to-directory
+function, keyed by workspace identity (path fallback) and session ID. Only that session directory
+is readable; workspace files and other sessions are rejected, with no legacy path fallback.
+Creation failures surface before the runtime advertises a writable directory. HTML stays on the
+execution machine; widget state stays on the desktop. Neither storage belongs in the Git workspace.
+
+State storage is an injected adapter. Atomic file replacement and the existing cross-process file
+lock serialize full snapshots; notifications project durable state. Only modelContent is exported
+as untrusted next-turn context. Main owns native sandbox resources, not persisted state.

+Host 服务是 UI 与 Agent MCP 之间的桥；UI 通过 `IPluginUiBridgeService` 使用，不直接读取 HTML 或连接配置。
+
+- prepare 先向 Agent 取得来源绑定的运行凭证，再按 runtimeId/token/generation/resourceUri 合并资源读取与 Main 登记；不能仅按 renderer 提交的 scope 合并。资源读取前后由 Agent 检查连接代际。
+- HTML 上限 16 MiB，mimeType 仅接受 text/html;profile=mcp-app 或 text/html；超限拒绝，不截断。HTML 经 Host 到 Main，Renderer 只获取句柄。
+- 宿主从受信账号仓库读取 provider/profile.id 并哈希为 accountContext，不传 token。账号配置变更立即使在途 open 过期并关闭旧实例；同账号 token 刷新不触发换代。user_info 更新保守地重新验证实例。
+- validate/close/recycle 透传完整实例凭证；recycle 仅在 Agent 确认没有审批/调用 pin 时成功。调用归属、权限、取消和终态由 Agent 单一拥有，Host 不缓存执行结果或重放工具。
+- resources/read 原样返回 MCP contents，解码总大小限 8 MiB；Agent 同时检查 MIME 白名单。不裁剪内容，不经过模型摘要。
+- 只支持本地 workspace Agent；远程保持现有不支持/普通 MCP 卡回退。复用 Host attachment、workspace identity 和会话 lease，不新建远程宿主。
+
+- Sampling 仅透传到已存在的目标 workspace Agent，不新建/恢复执行、缓存结果或重放；超时/失败取消原 operationId。以严格 schema 返回官方基础 sampling 结果。
+
+Sampling 使用独立 `IPluginUiSamplingService` 描述符透传请求与取消，不扩张资源桥方法集合；Web/远程未注入时不声明 capability。

+Pure wire contracts for generated conversation UI. A reference identifies an executor-side file;
+it does not grant file access. The target Host authorizes and normalizes paths. Workspace identity
+and session isolate state. A state update replaces a JSON snapshot of at most 16 KiB. Only
+modelContent can enter bounded, untrusted model context. No MCP plugin identity or tool permission
+is implied by a generated UI reference.
+
+Tweak messages follow the upstream registration/update/disposal and ACK lifecycle. Each registration identifies one DOM target and at most 12 typed controls; preview changes carry registrationId, targetId, callback and previousValue. The page owner accepts at most 64 live registrations. This private Gen UI method grants no generic tool access.

+# mcp-apps-protocol
+
+纯 domain 模块，零 IO。持有 MCP Apps 的 CCbuddy 扩展常量、工具 `_meta` 归一化结果、`display.ui` 投影 schema 与沙箱契约类型。页面 ↔ 宿主的线协议（`ui/*` 方法、握手、版本协商、JSON-RPC、错误码）由官方 `@modelcontextprotocol/ext-apps` 承担，本模块不再复制方法名或 schema。
+
+类型与测试之外的不变量：
+
+- `resourceUri` 来源按优先级：`_meta.ui.resourceUri` → 弃用扁平键 `_meta["ui/resourceUri"]`（规范 MUST 兼容）→ `openai/outputTemplate`；必须以 `ui://` 开头且不超过 2048 字符，否则整个 `ui` 描述视为不存在，而不是部分接受。
+- `visibility` 缺省等于 `["model", "app"]`；不含 `"model"` 的工具不得进入 provider contracts；`readMcpToolVisibility(meta)` 独立于 resourceUri 读取。
+- agent 对每个 MCP server 的 `initialize` 必须宣告 `extensions["io.modelcontextprotocol/ui"].mimeTypes = ["text/html;profile=mcp-app"]`（`buildMcpAppsClientCapabilities`），否则按官方模板写的 server 只会注册纯文本工具。
+- CCbuddy 扩展能力一律放 `hostCapabilities.experimental["ccbuddy/…"]`（widgetState、resourceSubscribe、surface、csp），官方 SDK 的 zod 会剥掉标准位之外的未知键。
+- CSP 缺省按规范块；`'unsafe-eval'` / `'wasm-unsafe-eval'` 只在资源 `_meta["ccbuddy/csp"]` 声明为 true 时放行，未知键与非布尔值丢弃。
+- 沙箱句柄的 `shellUrl` 由 `sandboxId` 派生（`ccbuddy-sandbox://shell-<id>/`）；`partition` 由 server 身份派生（`persist:plugin-sandbox-v1-<hash>`），同一 server 的页面共享持久存储，卡片关闭不清；`sandboxId` 只含 `[A-Za-z0-9-]`（CSP host-source 字符集）。
+- 宿主 renderer ↔ relay shell 只有一条 MessageChannel（`PLUGIN_SANDBOX_PORT_NAME`），上面跑原始 JSON-RPC；shell 不解析协议。
+- `widgetState` 是 CCbuddy 扩展：初值经 hostContext 的 `ccbuddy/widgetState` 键随握手下发，页面经 `ui/set-widget-state { widgetState }` 交给宿主 renderer 内存保存（不持久化、无可见性参数；模型可见信息一律走 `ui/update-model-context`）。
+- `_meta.ui.surface` 与清单 surface id 共用字符集 `^[A-Za-z0-9][A-Za-z0-9_.-]*$`、≤ 128 字符，非法即丢弃。
+- 页面发起的 `resources/read` 边界常量在这里：`MCP_APPS_UI_READ_RESOURCE_MAX_BYTES`（8 MiB）与 `MCP_APPS_UI_READ_RESOURCE_MIME_ALLOWLIST`（以 `/` 结尾为前缀匹配，忽略参数与大小写）；执行方是 agent 的 mcp-ui。
+
+Gen UI 复用沙箱登记载荷，显式 `contentKind: "gen-ui"`，pluginId/serverName 留空且不允许权限声明；普通 MCP App 仍必须提供原来的插件与 server 归属。Gen UI 的页面业务 schema 独立位于 `@ccbuddy/shared/gen-ui`。

+# Gen UI
+
+Completed assistant references create bounded desktop sandbox pages. One page remains mounted while its inline/expanded anchor changes. UI hooks select the execution Host for file reads and base desktop Host for state and registration. Follow-ups use the existing session input binding; read-only, stale and hidden bindings cannot send. State changes alone never start an Agent turn. No tools are exposed.
+
+The window page owner shares admission and eviction capacity with MCP pages. Message components lease anchors and confirmation callbacks, not the guest lifetime. Natural-flow inline surfaces have no chrome, use content height (240px initial, 10,000px ceiling), and keep their node when elevated into a preview popover. Copy-image uses the owner-validated platform sandbox API. Tweak uses the object-binding runtime and serialized register/update/dispose acknowledgements. The page owner accepts registrations and projects preview commands; the old positional constructor is removed. Transient adjustments belong to the page owner, not a remounting panel.
+
+The conversation parent owns inline width. Normal and wide cards fill its content width without a separate maximum; the compensated paint gutter does not change that layout boundary.
+
+Reference projection accepts the Unicode JSON marker, `::visualize{path="..." title="..." mode="wide"}`, and `::visualize{"path":"...","title":"..."}`. The existing assistant directive parser locates boundaries; JSON decoding belongs only to Gen UI projection. All forms use the same strict reference schema, Markdown code exclusions, completion gate and original message offsets. Messages need no migration.

+# plugin-ui
+
+Renderer 模块，层序 `domain → app → adapters → components`；公开入口为 `index.ts`。
+
+- 窗口唯一页面管理器统一管理 MCP 与 Gen UI 的容量和回收；`createPage` 持有 MCP controller、AppBridge、独立 workspace/session lease、通知 feed 和内存快照。卡片、侧栏只登记锚点。内联页面位于滚动容器内部，侧栏单独定位；原子移动保留同一 guest，不重读资源、不重新握手。解绑必须在 DOM 卸载前同步移入隐藏承载区。
+- 逻辑键包含 workspace identity（本地 fallback 为路径）、session、plugin、server、resource 和逻辑视图。surface 显式共享；普通工具只按明确的 widgetSessionId 与相同权限范围共享，否则按 toolCallId 隔离。禁止同回合同资源推断合并。
+- UI 不接触插件 HTML、数据库和连接凭据。经 `IPluginUiBridgeService` 获取句柄，平台端口只校验 sandboxId/initId；请求与 live 通知绑定 Agent runtimeId/generation/token/appIdentity。
+- 官方 ext-apps 2.0.0 每活页面一个 AppBridge；握手期限 15 秒。保留 `experimental["ccbuddy/…"]` 的 widgetState、resourceSubscribe、surface、CSP 扩展；不模拟完整 OpenAI API。
+- App-provided tools 在 initialized 后发现与登记；认领后用官方 SDK AbortSignal 执行，模型取消沿 live-only delta 到页面。callId 去重，终态结果不可再写入。页面调用 MCP 的目标由宿主固定，复用 Agent 的权限和审批路径，原始结果直接返回。
+- 页面 `availableDisplayModes` 是硬约束；inline/fullscreen 对应内联/侧栏，pip 保持当前模式。高度默认 240px、范围 [80,1200]，hostContext 只回传 width/maxHeight，避免高度回环。布局按帧合并。
+- widgetState 仅接受页面主动提交，唯一内存 store 按逻辑键隔离；重建时在 `hostContext["ccbuddy/widgetState"]` 下发。切位置不复制；手动重试、任务淘汰、来源撤销清除；应用重启为空。
+- 连续离屏 5 分钟回收活页面；侧栏展示或有审批/调用时不回收。Agent 原子确认空闲后才释放。最多 30 个任务和 64 个活页面，容量 admission 串行；无法安全回收时返回错误。任务删除同时取消排队创建。
+- 已获准的主动释放先按原 sandboxId 解除导航/崩溃监听，避免 Main 停止页面的 about:blank 导航误报崩溃；真实运行中的导航/崩溃仍进入 error，重试后重建。
+- 释放顺序：失效凭证、取消调用和登记、有界 resource-teardown、关闭端口/guest、释放 feed/lease。迟到 prepare、注销和锚点清理只作用于捕获的原实例。卡片卸载不切断保活页面的订阅。
+- `sendFollowUpMessage` 仍走既有会话动作和手势/可编辑确认；确认完成后验证实例。只读会话不登记动作。`updateModelContext` 只投递到该 workspace/session 的 composer，不是数据库状态。
+- `display.ui` 无效、Web/手机/远程、不支持平台或初始化失败继续普通 MCP 卡回退。工具行替代与折叠策略仍由投影派生；不会另建 accepted-input queue 或改变 continuous/replayable 语义。
+- 工具失败、取消或 `display.ui.isError` 只保留普通工具记录，不占用 inline/侧栏区域、不自动开侧栏，手动固定/showInline/最近回合不能越过此门禁；失败不替代已有成功页面。原始错误结果及页面通知语义保持不变。
+- 工具行裁决与手动固定由 `pluginUiInstanceStore` 的同一会话条目持有，统一使用 `buildPluginUiSessionKey`。时间线挂载持独立 lease，最后一次幂等释放后才进入闲置 LRU；最多保留 30 个闲置会话，挂载中的会话不淘汰。写入、挂载、最后释放更新活跃顺序，读取无副作用。页面 owner 移除任务时请求清理：有 lease 则标记待清理并保留现有裁决和 pins，直到最后一次释放后直接删除，不进入 LRU；没有 lease 则立即删除。实际清理时同时释放裁决与 pins 并通知订阅；重复请求/释放幂等，旧 lease 不得清理同 key 的新条目。返回未淘汰会话保留手动偏好，淘汰后重新派生并恢复默认折叠。此缓存不持有沙箱，卸载/淘汰不得销毁离屏或侧栏活页面。
+
+组件只经 hooks/服务端口访问外部能力；controller 不导入适配器，domain 只做纯计算。侧栏 tab、composer 上下文仍由既有 UI owner 持有，不与页面状态重复写入。
+
+`preferredDisplayMode: fullscreen` 每次实际工具调用只消费一次；记录归既有侧栏内存，按 workspace/session/plugin/server/resource/toolCall 隔离，随其窗口缓存保留与淘汰。工具行重挂不能重新触发打开并覆盖收起偏好；已显示在侧栏时也消费该调用。手动打开、页面请求以及新工具调用仍走原入口。
+
+- Sampling 使用官方 oncreatesamplingmessage；只有可操作任务声明 sampling:{}。请求携带完整实例凭证，SDK signal 经显式 cancel 到 Agent；controller 将采样计入 busy，切展示位置不取消/重发。结果不进入主聊天；内容扩展和进度仍 pending。
+
+`hostPrimitives.ts` 对 Gen UI 公开 MessagePort 传输、原子移动页面承载层、窗口级容量管理、主题投影和会话动作读取。Gen UI 不复用 MCP 工具调用控制器。绑定显式区分自然流、容器定位与侧栏；Gen UI 预览使用原容器 popover，不重新挂载页面。
