DSH Code Review is a community code review plugin for DeepSeek Harness, packaged as @michengai/dsh-code-review. Enter /review, choose a scope or describe your request, and a native independent subagent inspects Git, source files, callers, and tests before returning a report to the main conversation. No Codex installation is required.

Host compatibility

The current version targets DSH 0.1.5-rc.2 and loads through dsh.bundle.patch. It requires the native spawn provider, the userQuestions service, a question answerer for your platform, and a model that supports tool calls.

Install the package from npm or build from source. Offline host and package integration checks have passed; review quality, language adherence, and interaction across platforms still need live validation.

What you can do

• Choose a scope: compare against a base branch, review uncommitted changes, select a commit, or provide custom instructions.
• Let the reviewer gather evidence: an independent context reads Git, relevant code, and tests without receiving a preloaded repository snapshot.
• Read results in the main conversation: receive prioritized findings with file paths and line numbers. Plain-text model responses are preserved.
• Use English or Chinese reports: a separate language context follows the host preference while preserving the original English Codex rubric.
• Check status or cancel: recover the latest report or cancel scope selection and an active review.

Prerequisites

• A working DeepSeek Harness installation with dsh available in PowerShell.
• Node.js ≥ 22.19.0, npm, and Git. Node.js must also meet your installed DSH version's requirements.
• Examples use the web profile; replace it with the profile running DSH.

DSH product ecosystem

For a desktop workbench, download DSH Codex Desktop. Existing DeepSeek Harness installations can add plugins as needed by following each project's README. Below are 11 first-party plugins; consult the corresponding desktop release notes and bundled catalog for what that version includes.

Plugin	What you can do
Codex UI	Organize projects and conversations, search tasks, and navigate chat turns
Agency Agents	Choose and summon specialists for your task
Skills Manager	Find, enable, create, and import local skills
Archive Manager	Search, restore, or clean up archived conversations
IM Connect	Send tasks and receive replies through messaging platforms
Automation	Schedule tasks and review each run
BTW	Ask side questions without interrupting the main task
Simplify	Use /simplify to improve code within your Git changes
PUA	Guide the Agent to try new approaches after failures, investigate causes, and verify results before completion
Code Review	Use /review to request an independent Agent code review and receive the report in the current conversation
Codex Pet	View conversation notifications and respond to tool approvals and questions through a desktop pet

Installation

Ask an agent to install it (recommended)

Send this prompt to an agent with local terminal access:

Install the DSH plugin @michengai/dsh-code-review into my local web profile: run dsh plugin --profile web add @michengai/dsh-code-review@latest --registry=https://registry.npmjs.org/, then dsh --profile web --dump-config. Confirm the plugin is loaded and explain how to restart DSH and use /review. Stop and report the cause if any step fails.

Install manually

Run these commands:

[Console]::OutputEncoding = [System.Text.Encoding]::UTF8
$OutputEncoding = [System.Text.Encoding]::UTF8
dsh plugin --profile web add @michengai/dsh-code-review@latest --registry=https://registry.npmjs.org/
dsh --profile web --dump-config

Continue only after each step succeeds. Restart the DSH backend you actually use, then enter /review. This is a native plugin, not a SKILL.md bundle; do not copy lib manually.

Usage

Goal	Input
Open scope selection	/review
Set a custom focus	/review Check the previous commit for authorization regressions
View progress or the latest report	/review-status
Cancel selection or an active review	/review-cancel

Empty input offers four options: base branch, uncommitted changes, a commit, and custom instructions. Uncommitted scope includes staged, unstaged, and untracked files. The base menu lists local branches; the commit menu lists the latest 100 commits. Other refs can be entered as free text.

All text after the command is treated as custom instructions, not CLI flags. --base main, ., and status are passed as ordinary text. The subagent determines and retrieves the context it needs. “Review the entire project” is passed verbatim, but does not mean the program has verified complete file-by-file coverage.

Configuration and reports

Optional setting	Behavior
reviewModel	Review model within the same provider; otherwise inherits the current model configuration
reportDirectory	Absolute report directory; defaults to $DSH_HOME/code-review, or ~/.dsh/code-review when DSH_HOME is unset

Language follows the host's locale.preference: en / en-* selects English; other values default to Chinese within the current two-language support. Each review captures the locale at its start; the next review reads updated settings. Command catalog descriptions and input hints are resolved when the plugin loads and require a reload to update. Without a saved preference or settings service, Chinese is used; the backend cannot read a language detected only in the browser.

The latest report is saved atomically per conversation. Historical report bodies are not translated. JSON keys, enum values, code, and paths remain unchanged. Unfinished reviews do not resume automatically after shutdown. Status, cancellation, and report storage are DSH plugin features.

FAQ

Is this identical to Codex?

The rubric and short task templates follow the fixed source commit a592c38c16cdd7623dacc9168926ebccedfb67d3. Questions, tools, permissions, and event presentation use native DSH capabilities. This is not a pixel-perfect Codex Desktop clone, and different models may produce different findings.

Can a review change code?

The review instructions request no fixes, but the tool layer is not universally read-only. Execution depends on DSH permissions and its sandbox. The never approval policy rejects operations requiring approval. Corresponding web, image, and further-delegation tools are restricted; third-party aliases are outside the verified mapping.

What if nothing appears after installation?

Check that installation and runtime use the same profile, restart the DSH backend, and confirm dsh --profile web --dump-config includes the plugin. Empty /review requires a host question answerer, and the main model must support the code_review tool. Use /review-status to inspect the record; a request acknowledgement is not review completion.

Why might I still see another language?

Explicitly select Chinese or English in host settings. Model language is controlled by instructions and cannot be guaranteed. Raw external-tool errors, code, and historical reports are not automatically translated.

Development and contributing

[Console]::OutputEncoding = [System.Text.Encoding]::UTF8

npm ci --ignore-scripts
npm run check
npm run verify:package
dsh plugin --profile web add .\michengai-dsh-code-review-0.1.0.tgz --ignore-scripts

check covers TypeScript, prompt hashes, short tasks, real AgentLoop regression tests with offline models, and documentation links. verify:package checks bundle loading, peers, and installed-package host integration in an isolated profile. These checks do not replace live model validation.

Entry	Responsibility
src/index.ts	Commands, main-session tool, and report delivery
src/selection.ts	Native scope selection
src/runtime.ts	Independent reviewer and tool restrictions
src/request.ts	Codex short tasks and base-ref resolution
src/i18n.ts	Host locale and output language context
