What changed

Adds Chats: sessions that belong to no project. Start one from Chats in the project rail or File → New Chat (Cmd/Ctrl+N). Chats are saved, listed in their own sidebar section, and can be moved into a project later from the composer's project picker.

  • Projectless sessions (cwd === "~") are now persisted, restored after a restart, and listed under Chats with the same rename, pin, archive, search and delete actions as project sessions.
  • Agents for a chat run in a folder the app keeps (<app data>/chats) instead of the home directory; if that folder can't be created it falls back to the old behavior.
  • Moving a chat into a project starts a fresh provider thread there and carries the conversation over as a handoff brief on the next turn. It is refused while a turn is running.
  • In a chat, the composer's project picker reads "Move to project" (or "Choose project" while the chat is empty) instead of a folder icon and ~, and the checkout and branch controls are hidden since a chat has no repo.

Closes #757

Why

Quick one-off questions currently need a throwaway project first, which adds friction and clutters the project list.

Summary by CodeRabbit

Summary by CodeRabbit

  • New Features
    • Start project-independent chats from the Chats section or with New Chat (Cmd/Ctrl+N). Chats are saved separately from projects and can be renamed, pinned, archived, searched, and deleted.
    • Move a chat into a project while carrying its conversation forward as a brief on the next turn. Files created in the Chats workspace remain there.
  • Improvements
    • Choose a project for an empty or finished chat. Chats with a user turn are saved and can resume after quitting.

📝 Walkthrough

Walkthrough

The change adds project-independent chats with a dedicated working directory and sidebar entry. Chats can be saved and resumed, and a nonblank chat can be moved into a project with its conversation retained as a handoff. New Chat is available through menus and a keyboard shortcut.

Changes

Projectless Chats

Layer / File(s) Summary
Chat workspace and harness routing
src/features/sessions/model/chatSession.ts, src-tauri/src/lib.rs, src/app/App.tsx, src/integrations/harness/core/registry.ts, src/integrations/harness/core/registry.test.ts, src-tauri/src/session_store.rs
The app creates and loads a chats directory. Harness calls use that directory for chats marked with cwd: "~", while project working directories remain unchanged. Session storage returns empty Git metadata for the chat marker.
Chat history and project promotion
src/features/sessions/data/sessionStore.ts, src/features/sessions/model/inFlight.ts, src/features/sessions/model/chatMove.ts, src/app/App.tsx, src/features/sessions/ui/SessionPane.tsx
Projectless chats can be listed and persisted after a user turn, and can qualify for resume. When a nonblank chat is moved to a project, the app clears selected provider and project state, adds a handoff when the brief is non-empty, and persists the moved session.
Chat navigation and shell
src/app/App.tsx, src/app/shell/Sidebar.tsx, src/app/shell/ProjectRail.tsx, src/app/shell/TitleBar.tsx, src/app/shell/SidebarChats.test.ts, src/features/projects/ui/*, src/features/sessions/model/chatSession.ts, CHANGELOG.md
The app can select or create a chat. The sidebar displays chat-specific labels, empty states, and Chats actions, and hides project workspace tabs in chat mode. The title bar and project pickers adapt their controls and labels for chats.
New Chat commands and shortcuts
src-tauri/src/menu.rs, src/app/shell/MenuBar.tsx, src/app/App.tsx, src/features/settings/model/*
The File menus and shortcut registry expose New Chat. Keyboard and native menu events invoke the new-chat callback.

Merge Risk: ⚪ Minimal · up to 8a80e

The change to the chat project picker labels works as intended, and no merge-blocking issue was found in the reviewed files.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 8a80e

Chats now survive restarts and can move between working folders. The inspected paths retain authorization and reset provider-thread state on promotion. Startup fallback and asynchronous process cleanup leave some uncertainty, but no introduced security vulnerability was established.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The examined exposure is the local user's agent workspace and retained provider identity. All projectless chats share the app-managed folder, and promotion carries conversation context into a user-selected project. Working-directory routing alone does not establish a sandbox or per-chat filesystem isolation.

Trust Boundaries and Controls

  • observed — Controlled harness turns authorize the resolved execution cwd before invoking the provider. Native authorization canonicalizes the path, rejects conflicting orchestrator ownership across sessions or windows, and conditions app access on eligibility. Inspected Claude and Codex reuse guards also require matching cwd and provider account before resuming a thread.

Resilience and Maintainability Implications

  • observed — Inspected provider cleanup clears resume/live mappings and suppresses old updates, providing counterevidence against stale-thread reuse. Promotion nevertheless does not await cleanup. OpenCode teardown performs asynchronous abort and stream closure before session-keyed unwatch and kill operations; ordering against a subsequent project's child remains unresolved.

Hardening Proposals

  • proposed — Make workspace readiness and fallback explicit before accepting chat turns, so users can distinguish app-folder execution from compatibility home-directory execution.
  • proposed — Give promotion an acknowledged transition state that orders provider retirement before a destination turn and reports persistence failure. This would strengthen cleanup ownership and recovery guarantees without treating the unresolved ordering as a verified vulnerability.

Could we remove "current checkout" and "no repo" indicators from the composer? Pretty useless for projectless chats and it gives the composer a cleaner look. @shohihul

Also, I think the chats shouldn't show under the project rail. Can we give it a separate section like projects? Looks cleaner that way. What do you think?

Thanks @EricRasputin! The composer indicators are removed in 2176462.

I'd prefer to keep Chats as a rail entry for now: the rail picks a container and the sidebar lists its sessions, so chats get the same rename, pin, archive and search as project sessions. A list in the rail would disappear when it's collapsed and isn't there in Classic. @hardbeat920, happy to change it if you'd like a separate section instead.

🔒 Security & Privacy | 🟠 Major | ⚡ Quick win

Wait for the Chats path before dispatching projectless turns.

If an OpenCode chat turn starts before chat_workspace_dir resolves, chatWorkCwd can pass "~" to the harness. The Tauri launcher expands it to the user’s home directory and starts the provider there. In OpenCode auto mode, the app allows read and edit for "*", so the agent can read or edit home-directory files. Wait for the Chats-path lookup to settle before dispatching projectless turns. Release the wait on failure to preserve the existing home-directory fallback.

Pushed 8a80e40: in a chat, the composer's project picker now reads "Move to project" (or "Choose project" while the chat is empty) instead of a folder icon and ~. I also updated the PR description.
