English | 简体中文

Clickable file paths in DSH replies — a DeepSeek Harness (DSH) web plugin with a Codex-style experience.

Unofficial project: independently developed and maintained by a community member, not an official DeepSeek product.

Screenshot

Inline paths wrapped in backticks (`~/...`, absolute, relative, or Chinese paths) become click-to-open; each clickable path carries a small folder-icon button that reveals the file in your file manager; a "📎 mentioned files" chip list at the turn tail covers the rest. URLs are already auto-linked by the official renderer, so this plugin leaves them alone.

The external-drive whitelist (Settings → Plugins → file-mentions): local files in your home directory are clickable by default; only external drives / network volumes (e.g. /Volumes/USB) need their root added here — one path per line. System-disk marker directories (/System, /etc) are rejected automatically.

Features

Where	What	Effect
Inline path text	click	Open with default app / open directory
folder icon after inline path	click	Reveal in file manager
"📎 mentioned files" chip	click name	Preview content inside DSH
folder icon in the chip list	click	Reveal in file manager
Inline URL	click	Browser opens it (official autolink)

Supports ~/ expansion, relative paths (resolved against the session cwd), and absolute paths in macOS / Linux / Windows forms. Non-existent paths silently do nothing.

Install

This repository is an official bundle plugin (dsh.bundle + dsh.client in the root package.json), installed through the official profile manager:

# DSH 0.1.7 and later:
dsh plugin --profile web add "github:a903067276-rgb/dsh-file-mentions#main"
# DSH 0.1.5 and older (this release needs 0.1.7+):
# dsh plugin --profile web add "github:a903067276-rgb/dsh-file-mentions#v1.0.14"

Then restart dsh web (bundle layers are composed at startup; HMR does not apply). Requires pnpm on PATH (dsh plugin forwards to pnpm).

Manual mount fallback: see docs/install.md.

Usage

Have the agent wrap paths in backticks (e.g. `~/docs/plan.md`) to make them clickable inline. The tail chip list appears automatically — no configuration.

Paths outside the session directory (external drives, etc.)

Local files inside your home directory (e.g. ~/Downloads, ~/Desktop) are clickable by default — no configuration needed. For paths on an external drive / network volume (e.g. /Volumes/USB), add that root to the external-drive whitelist in Settings → Plugins → file-mentions (one path per line). Saving takes effect immediately — no restart required.

System-disk protection: whitelist roots containing system marker directories (/System, /etc, or \Windows on Windows) are rejected automatically, so a full system disk mounted externally can never be whitelisted by mistake.

Platform support

Platform	Status
macOS	✅ Fully tested (incl. Chinese paths)
Linux	⚠️ Not tested — expected to work (command branching and path parsing implemented)
Windows	⚠️ Not tested — expected to work (command branching and path parsing implemented)

Requirements

• DSH web >= 0.1.0-rc.6 (run with npx @deepseek-ai/dsh web)
• Version compatibility (best effort — the settings card uses dual-field key+id registration to satisfy both rc.6 (id) and rc.7+ (key); verified locally on rc.6/rc.8/0.1.1-rc.2/0.1.2-alpha.2/0.1.5-rc.1 (clickable paths + "mentioned files" panel), not guaranteed on every DSH version):
  • DSH 0.1.0-rc.6 and newer (incl. 0.1.1-rc.1/rc.2 and 0.1.2): try main (default).
  • DSH 0.1.5-rc.1: load-verified (the plugin is in the client bundle and /api/file-mentions/check responds); UI interactions were not eyeballed item by item. ⚠️ 0.1.5 ships a narrow built-in "clickable inline-code paths in the closing reply" (only files written via write/edit/present in that turn — see dsh-client-ui-deliverables), which partially overlaps; plain-text/bare paths, cross-turn and historical messages are still handled only by this plugin.
  • Conservative fallbacks (the last pre-0.1.1 build): DSH 0.1.0-rc.7/rc.8 → v1.0.8 (dsh plugin add github:a903067276-rgb/dsh-file-mentions#v1.0.8); DSH 0.1.0-rc.6 → frozen rc6-compat tag (no maintenance).
• Pure Node stdlib implementation — peer dependencies (@deepseek-ai/dsh-settings, @deepseek-ai/schemastery) are provided by the host
• Opening files uses the system default app / file manager (per-platform command branching)
  • ✅ DSH 0.1.7 and later — use this release (v1.1.0): it declares peerDependencies: {"@deepseek-ai/dsh": ">=0.1.7-rc.1 <0.2.0"}, so a mismatched host refuses to load it with an explicit reason instead of failing quietly. Settings move to the 0.1.7 model (plugin Config, live-editable .volatile() fields), so changes apply without a restart.
  • ⚠️ DSH 0.1.5 and older — install the previous tag v1.0.14: that line keeps the old behavior and uses no 0.1.7-only API.
  • ⛔ Old plugin releases (up to v1.0.14) are not supported on 0.1.7 — the external-disk whitelist silently becomes empty (settings.get is gone). Upgrade the plugin together with the host.
• Maintenance policy: this plugin keeps evolving with the latest DSH releases; compatibility with older DSH versions is best-effort only and not guaranteed going forward.

How it works

• Host (lib/index.js): three routes — /api/file-mentions/check (existence check), /api/file-mentions/open (system open, mode: open/reveal, per-platform command) and /api/file-mentions/config (whitelist read/write for the settings page). All three routes are same-origin guarded. Probe surface: absolute/~/ paths are checked only inside the session cwd or user-declared whitelist roots (stored via the official settings service — immediate effect, no restart); whitelist roots are protected against system disks and symlink escapes. Pure Node stdlib; execFile avoids shell injection.
• Client (lib/client.js): a conversationEvents collector extracts paths from each reply → publishes them to turn data → the tail list filters non-existent paths before rendering; inline clicks use a document-level click delegation (the official render entry is occupied by the official "deliverables" plugin, so DOM delegation is the only viable path); inline folder-icon buttons are inserted by a MutationObserver and restored automatically after React re-renders; a settings card (sidebar section + plugin page) edits the whitelist. Scanning/decoration is incremental: the observer callback only handles newly-added nodes inside the official message area ([data-conversation-scroll]), each new text is cheap-screened for path-like characters (no /, ~ or \ → skipped with zero regex work and zero requests), and existence checks hit only the current session — conversations without paths trigger no scanning at all; sidebars, hover cards, menus and settings are never touched (v1.0.13).

See docs/architecture.md.

Notes

• Use either the official bundle install or the manual mount — never both.
• Manual mounting needs a single entry in ~/.dsh/cordis.patch.yml; a double entry applies the plugin twice and crashes on duplicate route registration.

Compatibility notes

• Inline clicks rely on backtick-wrapped paths (the agent-output convention, same as Codex); bare paths inside message text are clickable too (decoration is CSS-Highlight only, zero DOM mutation; message area only — sidebars, hover cards, menus and settings are never touched, v1.0.13).
• The official "produced files" list and this plugin coexist: official wins when it has output, otherwise this plugin shows.
• Windows / Linux validation via issue or PR is welcome.
