Introduction
dsh-pathlink
Ctrl+click file paths and links in DeepSeek Harness chat.
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, macOSopen -R, Linuxxdg-openon 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.


① Hovering a path shows the Ctrl+click hint — Ctrl+click opens the containing folder with the file selected · ② The recognized path in a real conversation (dotted underline).
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, platformweb): 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 officialchatFileMentionsseam is deliberately not used so the plugin never conflicts with the built-in deliverables provider and covers every surface uniformly. - Host half (
pathlinkRemote service): one read-onlyopenmethod 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.
