What Changed

Right-clicking a markdown file-link chip in chat (messages and previews) now shows the same
shared file context menu as the changed-files tree, the diff panel, and the file browser:
Reveal in Finder / Explorer / Files and an Open with submenu of the environment's
detected editors, alongside the chip's existing preview, preferred-editor, integrated-browser,
and copy-path items. Two behavior details ride along:

  • Reveal previously disappeared from file-link chips in remote mode; the shared reveal is
    server-side, so it now works in every connection mode.
  • Markdown links that point outside the workspace carry absolute environment-host paths; the
    shared path resolution now accepts those directly instead of rejecting them.

The menu convention itself is documented for future surfaces in
docs/internals/file-context-menus.md, and "file chip" / "file context menu" are defined in
docs/internals/glossary.md.

Not touched: composer file-mention chips (they live inside the Lexical editor and need
environment context threaded into the decorator — listed as a follow-up in the new doc) and
mobile, which has no right-click.

Why

#11842 introduced the shared menu for the diff panel, changed-files tree, and file browser, but
message file-link chips kept their own private menu with a duplicated reveal implementation and
no Open with submenu — exactly the drift the shared module was meant to prevent. This PR closes
that gap and records the rule ("every file surface right-clicks into the shared menu") so the
next file surface starts from the convention instead of rediscovering it.

Stacked on #11842 — merge that first; this diff is only the delta on top.

Verification

  • pnpm exec tsc --noEmit in apps/web: clean.
  • pnpm test src/fileContextMenu.test.ts src/components/ChatMarkdown.test.tsx in apps/web:
    56 passed, 0 failed (includes new absolute-path passthrough cases).
  • Lint on touched files: no new warnings vs base.
  • Exercised in a running web client against an isolated home: right-clicking the
    ChatMarkdown.tsx chip in a message now offers Open in Cursor / Open / Reveal in Finder /
    Open with (submenu lists Cursor and VS Code) / Copy relative path / Copy full path.

UI Changes

Summary by CodeRabbit

  • New Features

    • Added a shared right-click menu for workspace files across the file browser, changed-files views, diff panels, and chat file links.
    • File menus can now reveal files in the environment’s file manager, open them with the default editor, or choose another available editor.
    • Added consistent path handling for workspace, repository, and absolute file paths.
  • Documentation

    • Documented file context menus and related file-surface terminology.
  • Tests

    • Added coverage for path resolution and available file-menu actions.

Right-clicking a changed file in the chat changed-files tree, the diff
panel, or the workspace file browser now offers Open (default app),
Reveal in Finder/File Explorer/Files, and an Open with submenu of the
environment's detected editors. Reveal rides the existing
shell.openInEditor reveal support and its shellRevealInFileManager
config gate, so the menu only offers what the environment can do.
The file browser only matched top-level menu ids, so editor choices
from the Open with submenu fell through and did nothing. Also cover
the touched helpers with docstrings.
Markdown file links carried their own right-click menu with a private
reveal action and no Open with submenu, diverging from the changed-files
tree, diff panel, and file browser. Build their menu from
useFileContextMenu instead: the shared reveal and Open with items now
appear beside the chip's own preview, preferred-editor, browser, and
copy actions, and reveal works in remote mode where the old one was
hidden. Absolute environment-host paths resolve directly so links
outside the workspace keep their actions.

Document the convention in docs/internals/file-context-menus.md and
define file chip and file context menu in the glossary.

Selecting an editor from the shared Open with submenu does nothing. api.contextMenu.show returns a child id such as editor:<id>, but sharedItems.find(...) only matches top-level items, so the activation branch is skipped and no later branch handles the child id. Handle editor:<id> selections explicitly, as the file-browser caller does, and activate them through fileMenu.

For a bare workspace link such as ChatView.tsx, the file menu operates on <cwd>/ChatView.tsx instead of the indexed file apps/web/src/components/ChatView.tsx, so Reveal/Open actions target a nonexistent path. Unlike openFileInPanel, the menuPath flow never calls findWorkspaceBasenameMatch; resolve the basename before supplying the menu path (or make the shared menu perform that lookup).

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR introduces a shared file-opening and file-manager reveal capability across five production UI surfaces, including new path resolution and shell dispatch logic. Its cross-cutting runtime behavior, together with unresolved medium-severity issues around submenu activation and path/header handling, merits human review.

Dispatch selections from the Open with submenu.

sharedItems.find searches only top-level items. The context menu returns an editor:<id> child identifier when the user selects an editor. The lookup fails, so the selection has no effect.

Search the submenu children before calling fileMenu.activate.

Proposed fix
-        const sharedClicked = sharedItems.find((item) => item.id === clicked);
+        const sharedClicked = sharedItems
+          .flatMap((item) => [item, ...(item.children ?? [])])
+          .find((item) => item.id === clicked);
         if (menuTarget && fileMenu && sharedClicked) {
           await fileMenu.activate(sharedClicked.id, menuTarget);

Reject drive-relative Windows paths.

The regular expression classifies C:src\index.ts as absolute. Windows resolves this path relative to the current directory on drive C. Line 61 then returns it unchanged, so an action can open or reveal the wrong file.

Require a slash or backslash after the drive separator.
