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 — click the file name to open it with the OS default application;
• View diff — a modal renders the turn's actual applied changes (whole-file content for new files) using the harness DiffBlock primitive;
• Reveal — 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 — 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) — 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 — POST /api/file-changes/reveal validates a JSON payload, loopback origin, and an absolute existing path before handing it to the platform opener.
