reveal-file

Right-click a produced file in DeepSeek Harness (dsh) Web chat and open its location in your OS file manager — with the file selected.

Features

• Right-click menu — "打开所在目录" appears on produced-file rows in chat
• Cross-platform — explorer.exe /select, (Windows), open -R (macOS), xdg-open (Linux)
• Feedback toast — success / failure notification in the corner
• Lightweight — pure DOM context menu, no framework, one REST endpoint

Requirements

• DeepSeek Harness (@deepseek-ai/dsh) with the web profile
• @deepseek-ai/cordis (bundled with dsh)

Installation

pnpm dsh plugin --profile web add reveal-file
pnpm dsh --profile web

Or add it to your profile's cordis.patch.yml:

- insert:
    - id: reveal-file
      name: 'reveal-file'

Usage

In a chat message, right-click any produced file row (the files the model wrote to disk). A small menu appears with 📂 打开所在目录. Click it — the file manager opens with the file selected.

How it works

Dual-face plugin:

• Host half (lib/index.js) — registers a REST endpoint /api/reveal-file/reveal on the dsh web server. It resolves the path through the fs service, then spawns the platform's reveal command via the subprocess service.
• Client half (lib/client.js) — listens for contextmenu events on produced-file rows and calls the endpoint with fetch().

Note: the host half uses the host webServer service. This is the correct pattern for a static host plugin — the dynamic-runner sandbox has no harness global.
