dsh-change-review

dsh-change-review

A session change-review plugin for DeepSeek Harness (DSH): automatically tracks file write/edit operations inside your session and renders them as line-level diffs with customizable colors — session-isolated, subagent-aggregated, and pushed live via SSE.

One package carries both the Host logic and the browser UI (dsh.bundle + dsh.client manifests).

中文说明

✨ Features

Feature	Description
Auto tracking	Listens to write / edit tool calls, records before/after content and timestamps
Diff view	LCS line-level diff: added (green) / removed (red) / context (gray) lines with both-side line numbers
Session isolation	Each session reviews only its own changes; switching sessions switches the review
Subagent aggregation	Changes made by subagents are aggregated into the root parent session
Live updates	SSE server push — the badge and list refresh instantly when files change (zero polling)
Revert changes	Undo ONE specific change (later non-overlapping changes are kept) or the WHOLE file (restore the pre-session snapshot; a file created in-session is deleted) — writes directly to disk
Per-turn review	Each turn's tail shows a card with THIS turn's changed files and expandable diffs (with per-op revert), distinct from the session-wide 「审查」tab
Count badge	The 「审查」(Review) tab shows the pending file count; badge background/text colors are customizable
Color customization	12 colors configurable under Settings → 修改审查 (Review), including the turn-tail card's background, border, and added/removed counts (different defaults); every color has an opacity slider (rgba), persisted in localStorage
Clean sidebar	Hides the Cordis plugin run indicator (cordis-panel) from the left sidebar

Installed from the plugin market

📦 Install

Option A: dsh plugin add (after npm publish)

dsh plugin --profile web add dsh-change-review

Option B: manual deployment

1. Make the package resolvable by the harness (e.g. place it in node_modules) and register it in the profile's cordis.patch.yml:

- insert:
    - id: diff-review
      name: 'dsh-change-review'
    - id: ui-diff-review
      name: 'dsh-change-review'

2. Restart dsh web

This plugin targets the Web profile (dsh --profile web).

🚀 Usage

1. Open a session and click the 「审查」(Review) view tab (after「对话」Chat, before「轨迹」Trajectory)
2. Left: file list (write/edit counts, ~added/~removed stats); right: the selected file's diff. The two panes scroll independently (scrolling the file list never scrolls the diff preview and vice versa), so you can browse files while keeping the preview in place. The header toggle switches the scope: 此会话 (all session changes) or 最新一轮 (the latest turn's changes)
3. The badge increments in real time when files change; top bar: ↻ refresh, 清空 clear the current session's records
4. Revert (each action asks for confirmation, then writes the file on disk directly):
   • One change: the 撤回此项 (revert this) button on each edit/write section header — restores the file to that change's previous content, keeping later changes that do not overlap (overlapping ones are rejected with a hint)
   • Whole file: the 撤回全部修改 (revert all) button at the top of the detail pane — restores the file to its state before this session's first recorded change; a file created in this session is deleted
5. Per-turn review: after each turn, a 本轮变更审查 card appears at the turn's tail listing the files changed in that turn (write/edit counts, ~added/~removed); click a file to expand its diffs and revert a single change. Session-cumulative changes stay in the 「审查」tab — the two views are independent
6. Colors: Settings → 修改审查 (8 items + light/dark presets + restore defaults), auto-saved, survives refresh

🧠 Behavior Notes

• Scope: all write/edit tool calls in the current process, bucketed per session; subagent changes are aggregated up the owner chain to the root parent session
• Real time: the Host pushes via SSE (/diff-review/events); the client only processes events for the current session
• Persistence: colors persist (localStorage key dsh.diff-review.colors); review records persist to disk (~/.dsh/profiles/web/diff-review-state.json, debounced auto-save + sync flush on exit) and are restored automatically after a dsh web restart — delete that file to wipe all history
• Capacity guards: max 100 ops per file; content truncated at 120KB per op; diff capped at 1500 lines per side; the 3-way merge used for single-change revert is capped at 2000 lines per side
• Revert internals: each op records the full before/after content snapshot reported by the write/edit tool. Reverting the last op restores the exact snapshot; reverting a middle op performs a 3-way line merge (keeps later changes, removes that op) and refuses on overlap; after a successful revert the op and everything after it leave the pending list
• Upgrade note: records created before this upgrade (no content snapshots) cannot be reverted (no button is shown); Host-side changes require restarting dsh web, browser-side changes only need a page refresh
• Turn bucketing: each op records the ROOT session turn it happened in by scanning the session log (turn/start/turn/end) directly — no event-listener dependency, so resumed sessions and multi-turn sessions are attributed correctly; subagent changes count toward the parent turn. Per-turn cards and the review page's 最新一轮 view show only that turn's ops. Records created before this upgrade carry no turn and never appear in per-turn cards (they still show in the 「审查」tab)

📝 Changelog

v0.2.4 — File tree, context menu & race fixes (2026-08-17)

• Fix UI confusion — async fetch races (rapid session switches / file selection), stale state after session switch, and missing SSE reconnect sync are all fixed with request sequencing tokens, proper state reset, and es.onopen resync
• Grouped file tree — the review page's file list now groups files by directory (collapsible folders with file counts), making it easier to navigate projects with many changes
• Right-click context menu — both the review page file list and the per-turn review card (file rows + produced chips) support right-click to 打开文件 (open in the selected editor or Preview panel) or 在 Finder 中展示 (reveal in file manager)
• Editor picker — a code-editor selector is added to the session header (left of the session log button). It auto-detects installed editors via which and /Applications paths. The button shows "用xxx打开" with the editor's own app icon (served by the /diff-review/editor-icon/:id route, which reads the .icns from the app bundle and converts it to PNG). The selected editor is used for all 打开文件 actions; with no selection, the OS default handler is used. The choice is persisted in localStorage. The server route /diff-review/open-with-editor dispatches the editor command on the Host side. Detection also resolves the app bundle's real executable path (execPaths), so editors open via their own binary even when the CLI is not on PATH. File paths are resolved using the recorded cwd from the tool execution, ensuring relative paths are correctly converted to absolute paths.
• New-workspace session tracking — summary/detail/turn routes now fall back to the resolved root session id when a direct lookup misses, so new sessions created in a fresh workspace still get their file modifications tracked.
• Reveal in Finder — the context menu adds 在 Finder 中展示, which reveals the file in the file manager (open -R on macOS, explorer on Windows, xdg-open on Linux).
• Flat file list — the file list now shows files in a flat list (no directory grouping). File names and modification stats are on the same row for a more compact layout.
• Layout hardening — .drv-view remains stable across all conversation phases

v0.2.3 — Independent pane scrolling (2026-08-16)

• Independent scrolling — the review page's left file list and the right diff preview now scroll separately (the view fills the available height in every phase and overscroll-behavior: contain stops scroll chaining between the panes), making it easier to browse files while reviewing a diff

v0.2.2 — Fix plugin registration (2026-08-16)

• Fix plugin load — the client bundle is now registered under the correct dsh-change-review id (was @deepseek-ai/dsh-client-ui-diff-review), and the duplicate ui-diff-review insert was removed from cordis.patch.yml, so the plugin is injected once and loads correctly

v0.2.0 — Revert & per-turn review (2026-08-15)

• Revert changes — undo ONE specific change (3-way merge keeps later non-overlapping changes; overlapping ones are rejected) or the WHOLE file (restore the state before the session's first change; a file created in-session is deleted). Writes directly to disk after confirmation
• Per-turn review — each turn's tail shows a 本轮变更审查 card with that turn's changed files and expandable diffs; the 「审查」tab gains a 最新一轮 (latest turn) scope toggle
• Persistence — review records now survive dsh web restarts (~/.dsh/profiles/web/diff-review-state.json; debounced auto-save + sync flush on exit)
• Upgrade note — records created before this version carry no content snapshots or turn tags: they stay visible in the 「审查」tab but cannot be reverted; restart dsh web after upgrading

v0.1.0 — Initial release

• Session-isolated tracking of write/edit tool calls with LCS line diffs, subagent aggregation, SSE live updates, customizable colors, count badge
