What Changed

Skill mentions in sent messages are now clickable and keyboard accessible.

Selecting a skill chip:

  • opens its SKILL.md in the file panel
  • works for project, personal, system, and plugin skills
  • shows the skill path in a tooltip
  • keeps the skill directory available in the file explorer

File panel surfaces now support files outside the project root without changing existing project-file behavior. The composer documentation was also updated.

Video verification:

Screen.Recording.2026-08-24.at.5.10.08.PM.mov

Why

Skill chips previously showed which skill was used, but they did not provide access to its instructions. Users had to find the skill path and open the file manually.

This change uses the path already reported by the provider and opens it through the existing environment-aware file panel. This also works with remote environments because file access stays on the server that reported the skill.

Verification

  • vp run --filter @t3tools/web typecheck
  • Targeted lint and formatting checks
  • vp test run src/rightPanelStore.test.ts --project unit
  • 37 existing right-panel tests passed
  • Manual test

Checklist

  • This PR is small and focused
  • I explained what changed and why

Note

Medium Risk
Touches persisted right-panel state (storage v12) and file-tab identity, so a bad migration could reopen the wrong file tabs. Opening skill files uses existing environment-aware file access rather than new auth.

Overview
Makes $skill chips in sent chat (and review comments) clickable: they open the skill file in the right panel, show the path in a tooltip, and keep the skill directory as the explorer root.

File tabs now carry an optional RightPanelFileRoot so the same relative path under different roots is a distinct tab. Surface ids are encoded as file:project:… vs file:root:… (persisted state v12). The file preview uses that root’s cwd/label when present.

Copy-path and markdown copy treat skill chips like file links so they stay intact. Composer docs mention the new click-to-open behavior.

Note

Make inline $skill chips clickable to open skill files in file panel

  • Inline $skill tokens in chat markdown now render as interactive SkillChip buttons that open the underlying skill file in a rooted right-panel tab, with a tooltip showing the path
  • Introduces RightPanelFileRoot ({ cwd, label }) and rightPanelFileSurfaceId so file surfaces distinguish project-relative files from rooted ones; openFile in useRightPanelStore accepts an optional root and label
  • Threads fileRoot, threadRef, and cwd through ChatMarkdown, FilePreviewPanel, MessagesTimeline, and renderSkillInlineMarkdownChildren so chips and links resolve against the correct root context
  • RightPanelTabs title fallback and copy-path resolve against the tab's root cwd; clipboard sanitization preserves the chat-markdown-skill-chip interactive class
  • Risk: RIGHT_PANEL_STORAGE_VERSION bumps 11→12; migratePersistedRightPanelState in rightPanelStore.ts recomputes file surface ids and carries forward root/label — verify migration handles existing persisted tabs without losing selection

Macroscope summarized 6441e56.

Summary by CodeRabbit

  • New Features

    • Skill mentions now show their source path and can open the corresponding file in the file panel.
    • File previews preserve workspace roots, keeping files with identical paths from different roots distinct.
    • File tabs display clearer root labels, and copied paths respect the active workspace.
    • Skill chips retain their appearance when copied from chat.
  • Documentation

    • Updated skill and command documentation to explain source locations and file-opening behavior.

📝 Walkthrough

Walkthrough

Skill metadata now includes source paths. Inline skill chips resolve and open skill files. Right-panel file surfaces preserve workspace roots, use root-aware IDs, and display labels.

Changes

Skill file navigation

Layer / File(s) Summary
Root-aware file surfaces
apps/web/src/rightPanelStore.ts, apps/web/src/rightPanelStore.test.ts, apps/web/src/diffFileActions.test.ts
File surfaces accept roots and labels. Rooted and project-relative files use distinct encoded IDs. Persisted surfaces migrate to the new format.
Skill chip file targets
apps/web/src/components/chat/SkillInlineText.tsx, apps/web/src/components/composerInlineChip.ts, apps/web/src/markdown-clipboard.ts
Skill chips resolve POSIX and Windows paths. Valid targets open through the right-panel store. Sanitization preserves skill chips and file links.
Context and surface wiring
apps/web/src/components/ChatMarkdown.tsx, apps/web/src/components/chat/MessagesTimeline.tsx, apps/web/src/components/ChatView.tsx, apps/web/src/components/RightPanelTabs.tsx, apps/web/src/components/files/FilePreviewPanel.tsx, docs/user/composer.md
Skill paths and root context flow through markdown and timeline rendering. File previews, tabs, pending changes, copy-path actions, and documentation use the root-aware behavior.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 6441e

Skill mentions can now open files from roots outside the project, but approved-root validation is not established and persisted root handling has validity edge cases; an existing cwd mismatch can also break some relative links. Merge should wait for owner acceptance or fixes for these bounded risks.

UI consistency review

One concrete regression introduced by the new clickable chip, plus one shared-treatment suggestion.

  • apps/web/src/components/chat/SkillInlineText.tsx: rendering the chip as a native <button> makes it disappear from the text/html clipboard flavor, because the markdown clipboard sanitizer strips every button in a copied selection.
  • apps/web/src/components/chat/SkillInlineText.tsx: the fuchsia skill-chip treatment is now duplicated across both render branches and diverges from the existing named skill-chip variant.

Two findings on the surface-id and tab-title changes. The earlier notes on SkillInlineText.tsx (clipboard HTML flavor, duplicated chip class strings) still apply and are not repeated here.

One new styling-ownership finding on the shared chat skill-chip constant. The previously reported stale apps/web/src/diffFileActions.test.ts surface-id literals (file:apps/web/src/components/DiffPanel.tsx, file:Dockerfile) are still present and will now fail against rightPanelFileSurfaceId's encoded ids — see the earlier comment on rightPanelStore.ts.

Add direct unit tests for resolveSkillFileRoot.

resolveSkillFileRoot has several distinct path-format branches: a POSIX root-level path, a Windows drive-letter path, a nested directory path, and a missing-separator path that returns null. Add unit tests for each branch. This locks in the current behavior and catches regressions in the separator/root-boundary logic before they reach the file panel.

One consistency finding on the new clickable skill chip: its focus-visible ring is the only one in apps/web/src that does not use the semantic ring-ring token.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This adds a new clickable skill-file workflow across chat, review comments, and the rooted file panel, along with persisted right-panel identity and migration changes. The implementation is focused and uses existing file access, but the new user-facing behavior and cross-context state changes merit human review.
