What's Wrong?

"Show in Finder" right-click silently fails on relative-path markdown links

What Should Happen?

Summary

The right-click Show in Finder action on file links rendered in the chat transcript silently no-ops when the link uses a relative path. The menu closes with no Finder window, no error, no toast.

Environment

• Platform: Claude Code (desktop/web chat surface, not the terminal CLI)
• OS: macOS
• Model: Opus 4.7 (1M)

Expected

Finder opens in the foreground with the target file selected/highlighted (standard open -R behavior).

Actual

Menu closes. Nothing else happens. No Finder window, no error toast, no log entry visible to the user.

Workarounds that do work

• Copy path from the same menu returns a correct absolute path (so a resolver exists and is working for that sibling action).
• Asking Claude to run open -R "<absolute-path>" via Bash reveals the file reliably every time.

Hypothesis

The Show in Finder handler likely isn't resolving the relative path against the session's working directory before passing it to Finder, so the target resolves to a non-existent path and the native action silently no-ops. The Copy path handler appears to resolve correctly, suggesting the resolver exists but isn't wired into the Finder-reveal path — or its error branch swallows failure without surfacing feedback.

Severity

Low functionally — workarounds exist. High friction — Claude Code itself emits relative-path markdown as the default shape for file references, so this is the most common link shape users encounter.

Suggested fixes

1. Resolve relative paths against the session CWD (or project root) before invoking the Finder-reveal native action.
2. If resolution fails, surface a toast/error rather than no-op silently.
3. At minimum, share the resolver already used by Copy path — it produces a usable absolute path.

Steps to Reproduce

Steps to reproduce

1. In a chat turn, Claude outputs a markdown link to a local file using a relative path, e.g.:

``markdown
[Governance/Specs/Foo/BAR.html](Governance/Specs/Foo/BAR.html)
``

1. Right-click the rendered link in the transcript.
2. Context menu shows three items: Attach as context, Copy path, Show in Finder.
3. Click Show in Finder.
