Problem

The Coder-only rewrite (0a7c463) deleted the _chat.tsx global shortcut dispatcher and gutted ChatComposer.tsx, silently killing features the UI still advertises:

  • chat.new (mod+n, mod+shift+o) and chat.newLocal (mod+shift+n) resolved to a command with no executor — every rebinding in Settings → Keyboard shortcuts silently did nothing
  • mod+scomposer.stash: the entire prompt-stash feature (store, badge, menu) was deleted as collateral
  • Escape no longer cleared thread multi-selection
  • editor.openFavorite, themeEditor.toggle, and script.*.run remained bindable but had no executor

Changes

  • Restore the _chat.tsx dispatcherchat.new routes multi-project setups through the palette picker (mirroring the sidebar button), single-project creates directly; Escape clears thread multi-selection
  • Port prompt stash back, adapted to the Coder model — text-only entries tagged with the source environment (pasted images are workspace file links in the prompt text), storage key bumped to v3 with legacy purge, ComposerBanner-based stash menu matching upstream's current structure, configured-shortcut hint in the empty state, cross-workspace restore warns that file links may not resolve
  • Remove dead keybinding surfaceseditor.openFavorite, themeEditor.toggle, script.*.run scaffolding; retired commands are dropped silently on config load instead of surfacing as "Invalid keybindings configuration" issues
  • Upstream alignment — converges with fix(web): show the configured stash shortcut pingdotgg/t3code#8437 (configured stash shortcut, identical approach) and adopts the fix(web): restore unified activity logs and composer banners pingdotgg/t3code#8734 banner-based menu structure; feat(web): attach PDFs, ZIPs, and other files to a turn pingdotgg/t3code#8236 (file-attachment stash) is inapplicable to the Coder model

Verification

  • Live end-to-end against the coder-live harness (real gateway + Coder workspace): stash/stash-restore/delete/persist-across-reload, chat.new/chat.newLocal/mod+shift+o, Escape clear-selection, palette guard, settings catalog contents
  • pnpm --filter @t3tools/contracts typecheck, pnpm typecheck:web, pnpm typecheck:server pass
  • Focused suites pass: contracts (159), server keybindings (25), web keybindings + stash (64), chat components (232)
  • pnpm build passes

Notes for reviewers

  • Default mod+n/mod+shift+n/mod+shift+o remain reserved by Chrome/Edge on Windows (Incognito, bookmark manager, new window) — users should rebind via Settings → Keyboard shortcuts; the restored commands now actually fire
  • Docs updated (docs/user/composer.md); docs/user/keybindings.md needed no change

    • Added global chat shortcuts for clearing selections and creating threads, including project selection when needed.
  • Bug Fixes

    • Improved restoration of terminal context and pending responses.
    • Improved handling when browser storage is unavailable or full.
    • Obsolete keyboard shortcuts are now filtered and migrated safely.
  • Documentation

    • Clarified prompt stash limits, browser-local storage, and image-link behavior.

… Coder fork

The Coder-only rewrite (0a7c463) deleted the _chat.tsx global shortcut
dispatcher and gutted ChatComposer, killing chat.new, chat.newLocal, the
Escape clear-selection handler, and the entire prompt-stash feature while
the docs and settings page kept advertising them.

- Restore the _chat.tsx dispatcher (chat.new routes multi-project setups
  through the palette picker, mirroring the sidebar button; Escape clears
  thread multi-selection)
- Port prompt stash back adapted to the Coder model: text-only entries
  tagged with the source environment (pasted images are workspace file
  links in the prompt text), storage key bumped to v3, ComposerBanner-
  based stash menu with the configured-shortcut hint, environment
  mismatch warning on cross-workspace restore
- Remove dead keybinding surfaces: editor.openFavorite, themeEditor.toggle,
  and script.*.run scaffolding; retired commands are dropped silently on
  config load instead of surfacing as configuration issues
- Align with upstream pingdotgg#8437 (configured stash shortcut in
  the menu) and the pingdotgg#8734 banner-based menu structure

Verified against the coder-live harness: stash stash/restore/delete/
persistence, chat.new/newLocal/Escape flows, palette guard, settings
catalog; contracts/server/web typechecks and focused suites pass.

📝 Walkthrough

Walkthrough

The change removes dynamic and retired keybindings, adds global chat shortcuts, and introduces browser-local prompt stash storage with composer controls, accessibility behavior, persistence handling, tests, and documentation.

Changes

Keybinding contracts and retirement

Layer / File(s) Summary
Keybinding contracts and retired-command cleanup
packages/contracts/src/keybindings.ts, apps/server/src/keybindings.ts, apps/server/src/keybindings.test.ts, packages/contracts/src/keybindings.test.ts
KeybindingCommand now accepts static commands only. Server loaders filter retired commands and preserve legacy file-search migration. Tests use supported commands and verify removal, persistence, replacement, caching, malformed input handling, and concurrency.
Web keybinding catalog and settings cleanup
apps/web/src/keybindingCatalog.ts, apps/web/src/keybindings.ts, apps/web/src/keybindings.test.ts, apps/web/src/routes/settings.shortcuts.tsx
The web catalog and settings page remove the Scripts category and dynamic script action discovery. Retired shortcut helpers, defaults, and tests are removed.

Global chat shortcuts

Layer / File(s) Summary
Global chat shortcut routing
apps/web/src/routes/_chat.tsx
The chat route installs global shortcuts for clearing selections and creating threads. Multi-project creation opens the command palette project picker; single-project creation remains direct.

Prompt stash

Layer / File(s) Summary
Prompt stash storage and composer integration
apps/web/src/promptStashStore.ts, apps/web/src/promptStashStore.test.ts, apps/web/src/components/chat/ChatComposer.tsx, docs/user/composer.md
The store validates and persists up to 20 prompt entries, supports memory fallback, hydrates versioned data, and reports durability. ChatComposer adds save, restore, delete, keyboard shortcut, menu coordination, and workspace warnings. Documentation describes text-only storage and workspace-linked images.
Prompt stash controls
apps/web/src/components/chat/ComposerStashBadge.tsx, apps/web/src/components/chat/ComposerStashMenu.tsx, apps/web/src/components/chat/ComposerStashBadge.test.tsx, apps/web/src/components/chat/ComposerStashMenu.test.tsx
The badge displays the stash count and menu state. The menu supports prompt snippets, timestamps, restore and delete controls, outside-click dismissal, Escape, arrow navigation, Enter, and modified Backspace.

99-110: 🗄️ Data Integrity & Integration | 🔵 Trivial | 💤 Low value

Consider validating the persisted version field.

readPersistedEntries decodes only state and ignores the stored version. Today the module writes version 3 under the v3 key only, so behavior is correct. If a later version writes a different shape under the same key without bumping the key, this reader silently accepts a partially compatible payload. A version check would make the failure explicit.

…terminal contexts visible after stash

Address the two actionable CodeRabbit findings:

- restoreStashEntry: while a pending user input is active, the composer's
  text is the question's custom answer, so a restore written only to the
  composer draft was clobbered by the answer sync and never submitted.
  Route it through onChangeActivePendingUserInputCustomAnswer, matching
  applyPromptReplacement.
- stashCurrentPrompt: clearing the prompt to an empty string while
  terminal contexts stayed in the draft broke the placeholder-count
  invariant, so the orphaned contexts were silently re-attached to the
  next prompt at send time. Re-insert their placeholders, matching the
  draft store's clear behavior and upstream's stash clear.

The version-validation nitpick in promptStashStore is skipped: the
store rejects unknown payload shapes on decode and shape changes come
with a new storage key (v1 -> v2 -> v3).
