If the request names other readers or users of the work (a team, a manager, a reviewer), or where it is headed to be posted or presented (a channel, a meeting), Claude publishes. For a short piece, Claude additionally puts the text in its reply so it can be pasted straight away. If the work could plausibly be forwarded but nobody has said so, Claude adds a one-line offer of the page rather than staying silent. If all the person wants is Claude's own judgement, as in "should we ship this?", and no other reader is mentioned, Claude answers in the terminal and, in place of publishing, offers the page in a single line. An analysis or recommendation prepared for somebody else to act on counts as complete work for its reader, and so it gets published. Apps, sites, dashboards and games always get published, as does anything requested as an artifact or as an HTML or Markdown page for viewing. If what is wanted is the file itself, as in "save these notes as a .md file" or "just give me the .html file", then Claude delivers that file and skips publishing.

That skill carries the page contract: the authoring format (HTML, with Markdown only at a loaded skill's request), the title, libraries, storage, the size cap, layout, theming and the icon. It also decides how much design effort a given request merits, and Claude never turns to Markdown to dodge it. Once the skill is loaded, Claude puts the content into a file (with Write/Edit) and passes that path to SpatialArtifact; if a scratchpad directory is listed in the system prompt and the person has not asked for some other location, the file goes there. diff --git a/plugins/spatial-artifacts/server/sample.ts b/plugins/spatial-artifacts/server/sample.ts deleted file mode 100644 index 379c3a1..0000000 --- a/plugins/spatial-artifacts/server/sample.ts +++ /dev/null @@ -1,475 +0,0 @@ -// the sample capability: a page asks Claude, billed to the key this machine's Claude Code runs with (ANTHROPIC_API_KEY, -// or ANTHROPIC_AUTH_TOKEN). raw https to the Messages API, streaming: the plugin has no runtime dependencies, so no SDK. -// each call is memory-less: the page's input under a fixed framing, its own tools run in the page round by round -import { createHash, randomUUID } from 'node:crypto'; - -export const PROMPT_MAX = 262144; -export const IMAGES_MAX = 5; -export const IMAGE_MAX_BYTES = 20 * 1024 * 1024; -export const IMAGE_TYPES = ['image/jpeg', 'image/png', 'image/webp', 'image/gif']; -export const TOOLS_MAX = 16; -const ROUNDS_MAX = 6; -const TOOL_WAIT_MS = 150000; -const RUNNING_MAX = 2; -const WAITING_MAX = 4; -const GC_DEFAULT = 300000; -const GC_MAX = 86400000; - -// opus answers by default; `quick` is the small, fast model.
