dsh-file-changes

A DeepSeek Harness Web plugin that
shows a file-change panel at the end of every answer. When a turn creates or
modifies files, the panel lists each one under the closing message with three actions:

• Open 锟斤拷 click the file name to open it with the OS default application;
• View diff 锟斤拷 a modal renders the turn's actual applied changes (whole-file
  content for new files) using the harness DiffBlock primitive;
• Reveal 锟斤拷 locate and select the file in the OS file manager
  (macOS open -R, Windows explorer /select,, desktop Linux opens the
  containing directory). The action appears only on loopback access with a
  native opener available.

The panel complements the built-in "Produced" row: it adds created/modified
badges, per-file diffs, and per-file filesystem reveal.

Install

# from GitHub
dsh plugin --profile web add git+https://github.com/mixin-ai/dsh-file-changes

# from a local checkout
dsh plugin --profile web add link:/path/to/dsh-file-changes

Restart dsh web, then refresh the browser page.

How it works

• Native mode 锟斤拷 the client half registers a conversation definition (like
  @deepseek-ai/dsh-client-ui-deliverables) that accumulates successful mutation
  tool calls from their presentation views (card: 'diff' hunks, or generic
  kind: 'edit' locations) into turn-scoped data published under the
  fileChanges key, and renders it through the chat view's
  conversation.chat.turnTail slot chain.
• Code Mode (run_code) 锟斤拷 nested dispatches carry no presentation views
  on the wire, so the host half listens to tools/execute / tools/result
  for executions with a parent (Code Mode sub-calls), rebuilds change
  records from the write / edit / str_replace_editor arguments, and
  serves them over /api/file-changes/changes. The panel merges both
  sources, deduplicated by path.
• Reveal 锟斤拷 POST /api/file-changes/reveal validates a JSON payload,
  loopback origin, and an absolute existing path before handing it to the
  platform opener.

Structure

File	Role
lib/index.js	Host half: nested-dispatch tap + the two HTTP routes
lib/client.js	Browser bundle: turn accumulator + panel/diff/reveal UI
cordis.patch.yml	Bundle patch mounting the dual-half row
smoke.test.mjs / client.test.mjs	Host and client logic tests

Run the tests with:

node smoke.test.mjs && node client.test.mjs

Limitations

• Files created indirectly by terminal commands (e.g. bash) are not
  detected 锟斤拷 the same vocabulary limit as the official produced-files row.
• Host-side Code Mode records live in memory (2-hour / 2000-per-session ring);
  a server restart clears them.
• The reveal endpoint trusts loopback same-origin JSON requests only.
