About Code Quality & Review
The best agent skills for code quality and review in 2026 are Claude Code's built-in code-review and simplify Skills — code-review runs the structured security-and-correctness pass a senior engineer makes on a PR, while simplify catches reuse and altitude problems that accumulate in working code. Code quality and review Skills turn an AI agent from a code writer into a disciplined code reviewer. They encode the structured pass — security, correctness, performance, simplification — that senior engineers run on a PR, and apply it consistently every time. The Anthropic-authored code-review and simplify Skills are the canonical examples; both ship inside Claude Code and replicate the rubric the Claude Code team uses internally.
The workflows are familiar. Reviewing an uncommitted diff before opening a PR. Catching N+1 queries and missing edge cases in a feature branch. Running a simplification pass on a refactor that grew too clever. Producing PR comments inline, or applying the fixes directly to the working tree. Test-driven workflows: drafting tests first, watching them fail, then implementing. Skills here also cover the meta-level — choosing between Claude Opus and Claude Sonnet for review, running multi-agent ultrareviews, and writing the review-bot persona for a specific repo's house style.
Engineering managers, staff engineers, and any team paying for code review at scale use these. We rank by composite score; provenance (Anthropic, well-known engineering orgs) and install count dominate, with documentation depth and cross-agent compatibility as tiebreakers. Skills that integrate with gh pr and post comments score higher for production use than read-only reviewers.

FAQ
Frequently asked
What is the difference between /code-review and /simplify?
code-review hunts for correctness bugs and security issues. simplify focuses on reuse, deduplication, and altitude cleanups — quality without bug-hunting. Use code-review before merge; use simplify after the change works.
Do code-review Skills replace senior engineers?
No. They catch the mechanical issues — injection patterns, missing null checks, race conditions, N+1 queries — so human reviewers can focus on architecture, naming, and intent. Best teams run both.
Can these Skills post inline PR comments?
The official Claude Code code-review Skill supports --comment to post findings as inline GitHub PR comments via gh, and --fix to apply them to the working tree.
Which model is best for code review?
Opus 4.7+ is the default for high-effort reviews. Sonnet 4.6 is the cost-efficient choice for routine reviews. The ultra mode runs a multi-agent review in the cloud.
Are review Skills cross-agent?
The Anthropic Skills are deepest on Claude Code. Cursor and Codex have community-published equivalents; Gemini CLI compatibility varies. Filter by agent on the listing page to see verified support.
