## Why Code Review in Claude Code

Reviewing inside the editor closes the loop between writing code and checking it. Instead of waiting for CI or a human reviewer to flag a problem, Claude reviews the change while the context is fresh — and because it can run several review passes in parallel, it surfaces issues a single read might miss. The result is fewer bugs and security holes reaching your pull request. The building blocks are a few first-party [Claude Code plugins](/blog/claude-code-plugins), plus optional review skills.

There is a second, subtler benefit: reviewing Claude's *own* output. AI-generated code is fast but not infallible — it can introduce subtle logic errors, insecure patterns, or inconsistencies with the rest of your codebase. Running a dedicated review pass over what Claude just wrote catches those before they land, turning "the AI wrote it" into "the AI wrote it and a second pass checked it." That self-review loop is where in-editor review earns its keep, and it is exactly what the plugins below automate.

## The code-review Plugin

Anthropic's official `code-review` plugin is the centerpiece. It runs **parallel agents** over a change set, each looking for a different class of problem — logic bugs, missed edge cases, unclear naming, style inconsistencies — then reports back before you commit. Install it with:

```text
/plugin install code-review@claude-plugins-official
```

Then ask Claude to review your staged diff or a specific file. It is the fastest way to add a rigorous second read without leaving the editor.

## security-guidance & pr-review-toolkit

Two more first-party plugins round out review:

- **`security-guidance`** — reviews diffs for injection, XSS, SSRF, exposed secrets, IDOR, and auth-bypass patterns. It **ships enabled by default**, so you may already have it; the right move is to leave it on. `/plugin install security-guidance@claude-plugins-official`
- **`pr-review-toolkit`** — adds pull-request-oriented review, from change summaries to line-level feedback, for teams that review at the PR level.

Both live in Anthropic's official marketplace, [`anthropics/claude-plugins-official`](https://github.com/anthropics/claude-plugins-official); see the [official Claude Code plugins](/blog/official-claude-code-plugins) list for the full first-party set.

## Skills for Code Review

Plugins do the heavy lifting; a **skill** makes review yours. Encode your team's review checklist, naming conventions, or house style in a `SKILL.md`, and Claude applies it every time it reviews — so the feedback matches how *your* team reviews, not a generic standard. This is where the skills and plugins hubs meet: the plugins provide the engine, a custom skill provides the standards.

## Setting Up a Review Workflow

A sensible default review stack takes two minutes:

1. Install `code-review@claude-plugins-official`.
2. Confirm `security-guidance` is enabled (it usually is by default).
3. Optionally add a review skill with your team's checklist.
4. Run `/reload-plugins`, then ask Claude to review staged changes before each commit.

## Conclusion

Claude Code makes in-editor code review a one-command setup: the official `code-review` plugin for correctness, `security-guidance` for vulnerabilities, `pr-review-toolkit` for PRs, and a custom skill for your team's standards. Install the two official plugins, add your checklist as a skill, and review every change before it ships.
