description: "Code review closeout for Claude Code, Codex, OpenCode, DeepSeek TUI, and Antigravity CLI: local dirty changes, branch vs main, parallel tests."

CC Review

Run automated code review as a closeout check before committing or shipping. Works across multiple AI coding agents.

Use when:

• user asks for code review / review-it / autoreview
• after non-trivial code edits, before final/commit/ship
• reviewing a local branch or PR branch after fixes

Supported Agents

| Agent | Review Command | Notes | |-------|---------------|-------| | Claude Code | `/review` | Built-in, works on uncommitted changes or diff | | Codex | `codex review` | Pass diff file or let it auto-detect | | OpenCode | `/review` | Same as Claude Code | | DeepSeek TUI | `/review` or manual diff review | Pass diff content for analysis | | Antigravity CLI | `/code-review` | Built-in slash command, auto-detects diff |

Contract

• Treat review output as advisory. Never blindly apply it.
• Verify every finding by reading the real code path and adjacent files.
• Read dependency docs/source/types when the finding depends on external behavior.
• Reject unrealistic edge cases, speculative risks, broad rewrites, and fixes that over-complicate the codebase.
• Prefer small fixes at the right ownership boundary; no refactor unless it clearly improves the bug class.
• Keep going until review returns no accepted/actionable findings.
• If a review-triggered fix changes code, rerun focused tests and rerun review.
• Stop as soon as the review comes back clean with no actionable findings.
• If rejecting a finding as intentional/not worth fixing, add a brief inline code comment only when it explains a real invariant or ownership decision that future reviewers should know.
• Do not push just to review. Push only when the user requested push/ship/PR update.

Review Focus

请 review 当前 diff。不要只看语法和明显 bug，请重点检查以下维度，最后按严重程度排序：

1. **隐藏副作用 (Hidden Side Effects)** — 变更是否在非显而易见的地方产生级联影响？是否修改了共享状态、全局变量、或外部依赖的行为？ 2. **破坏兼容性 (Breaking Compatibility)** — 是否改变了 API 签名、数据结构、配置文件格式、或命令行接口？现有调用方是否会受影响？ 3. **边界情况 (Edge Cases)** — null/空值/空集合、极大/极小值、并发/竞态条件、异常路径是否被正确处理？ 4. **性能风险 (Performance Risks)** — 是否引入了不必要的循环嵌套、N+1 查询、大对象分配、阻塞 I/O、或锁竞争？ 5. **安全风险 (Security Risks)** — 是否存在注入、越权、敏感信息泄露、不安全的反序列化、或依赖版本漏洞？ 6. **命名误导 (Naming Misleading)** — 变量/函数/类型名称是否与实际行为不一致？是否存在名不副实或语义模糊的命名？ 7. **测试不足 (Insufficient Testing)** — 关键路径、边界条件、错误处理是否缺少测试覆盖？现有测试是否真正验证了期望行为？ 8. **未来维护成本 (Future Maintenance Cost)** — 是否引入了不必要的抽象、重复代码、隐式耦合、或难以追踪的控制流？后来者是否容易理解和修改？

Pick Target

Claude Code / OpenCode / DeepSeek TUI

Dirty local work (default — `/review` works on uncommitted changes):

/review

Branch/PR work — review all changes against base:

First generate a diff, then review it:

git diff origin/main...HEAD > /tmp/review-it.diff

Then review the diff file with a focused prompt:

/review the changes in /tmp/review-it.diff against origin/main

If an open PR exists, use its actual base:

base=$(gh pr view --json baseRefName --jq .baseRefName)
git diff "origin/$base"...HEAD > /tmp/review-it.diff

Antigravity CLI (`agy`)

Dirty local work:

/code-review

Branch/PR work — review all changes against base:

git diff origin/main...HEAD > /tmp/review-it.diff

Then pass the diff to the review command:

/code-review the changes in /tmp/review-it.diff against origin/main

If an open PR exists, use its actual base:

base=$(gh pr view --json baseRefName --jq .baseRefName)
git diff "origin/$base"...HEAD > /tmp/review-it.diff

Codex

# Review uncommitted changes
codex review

# Review branch diff
git diff origin/main...HEAD > /tmp/review-it.diff
codex review /tmp/review-it.diff

Parallel Closeout

Format first if formatting can change line locations. Then it's OK to run tests and review in parallel:

scripts/review-it --parallel-tests "<focused test command>"

Tradeoff: tests may force code changes that stale the review. If tests or review lead to code edits, rerun the affected tests and rerun review until no accepted/actionable findings remain.

Uncommitted vs Branch Review

Choose the right mode:

• **Uncommitted changes** (staged/unstaged): use `/review` directly (Antigravity: `/code-review`, Codex: `codex review`)
• **Committed, not pushed**: use `git diff origin/main...HEAD` + review
• **Pushed/PR**: same as committed, against the PR base
• **Clean working tree**: skip review if there's truly nothing to review

Helper

Bundled helper script for parallel test + review orchestration:

~/.claude/skills/review-it/scripts/review-it --help

The helper:

• Detects which agent is running (Claude Code, Antigravity CLI, Codex) via `--agent auto`
• Detects whether to use uncommitted review or branch diff review
• For branch mode: generates diff against `origin/main` (or PR base), then triggers review
• Supports `--parallel-tests` for concurrent test + review execution
• Supports `--dry-run` for checking what command would be used
• Prints `review-it clean: no accepted/actionable findings reported` when review is clean

Final Report

Include:

• review target (uncommitted / branch / PR base)
• tests/proof run
• findings accepted/rejected, briefly why
• the clean review result, or why a remaining finding was consciously rejected

Do not run another review solely to improve the final report wording. If review exited clean with no actionable findings, report that as clean.
