Recognizes file paths and URLs in rendered chat messages (assistant replies, user bubbles, code blocks, tool cards), marks them with a subtle dotted underline, and opens them with Ctrl+click (⌘ on macOS):

Path → containing folder — the file's folder opens in the OS file manager with the file selected (Windows explorer /select, macOS open -R, Linux xdg-open on the parent directory). A path that names a directory opens the directory itself.
Link → new browser tab — covers bare URLs the renderer did not linkify (e.g. in user bubbles); markdown links already open in new tabs natively.

Plain clicks stay inert, so text selection and copy are never disturbed. When a path does not exist, a small toast explains why instead of failing silently.

The screenshot above is from the bundled local demo page (docs/demo.html), which reuses the exact production recognizer.

Install

dsh plugin --profile web add dsh-pathlink

or via GitHub:

dsh plugin --profile web add github:penguin-oo/dsh-pathlink

Restart the web GUI afterwards. Requires the web profile (a browser is the only surface that can receive the click).

Usage

Wait for a settled message that mentions a path or a link — recognized tokens get a dotted underline.
Hold Ctrl (or ⌘ on macOS) and click.
- Path → folder opens in Explorer/Finder with the file selected.
- Link → opens in a new browser tab.
Relative paths resolve against the session's workspace directory first, then the harness working directory; missing paths show a toast.

How it works

Client half (dsh.client, platform web): a MutationObserver-driven scanner watches the rendered conversation containers (data-chat-flow / data-conversation-scroll), recognizes paths and URLs in text nodes, wraps matches in inert inline spans, and handles one delegated capture-phase click listener. The official chatFileMentions seam is deliberately not used so the plugin never conflicts with the built-in deliverables provider and covers every surface uniformly.
Host half (pathlink Remote service): one read-only open method that resolves relative paths against the addressed session's working directory, verifies existence, and launches the platform file manager. No durable state; it never creates or resumes an Agent or Session.

Development

npm install
npm run build   # bundle src/client → lib/client.js
npm run smoke   # Remote markers + Typert manifest validation
node scripts/e2e-synthetic.mjs   # browser E2E against http://127.0.0.1:3738

docs/demo.html is built with node scripts/build-demo.mjs (reuses the production recognizer) and screenshotted by node scripts/e2e-screenshot.mjs.

Limitations

Web GUI only (the click surface is a browser); the host opener covers Windows / macOS / Linux.
Path recognition is heuristic: CJK directory names survive, but a path whose final segment is a bare English word (no extension) followed directly by prose may occasionally be over-matched — the existence check then shows the not-found toast instead of opening anything wrong.
