Best Claude Code Mods for Code Review
If you came here expecting a polished "top 10 code review mods" list, here is the honest version: the mods ecosystem is four days old, and nobody has built a dedicated code-review mod yet. What follows is what code reviewers actually install today — guards that protect your diffs, hooks you can build review automation on, and the checklist pattern doing most of the real work.
The honest answer first
Mods launched with Claude Code v2.1.287 on October 1, 2026. In the first wave, builders gravitated toward visible UI toys — live lines, dashboards, pixel pets — because those demo well. The unglamorous workflow mods (review gates, test runners, CI hooks) have not been built yet. That is not a criticism; it is simply where the ecosystem is.
So this page does two things: it shows you the closest existing mods to a code-review workflow, and it tells you what reviewers do instead right now. When a dedicated review mod lands, it will surface first in the community catalogue — and this page will be updated the same day.
What code reviewers actually install today
1. claude-code-redact — the guard your reviews need
claude-code-redact by karanb192 redacts secrets and PII before the model reads them. Why does that matter for code review? Because review means feeding diffs to the model — and diffs routinely contain API keys, tokens, and internal URLs. A redacting guard sitting in the pipeline means your review workflow stops leaking secrets by accident. It is the closest thing in the directory to review infrastructure, and it demonstrates the exact mechanism (a pipeline guard) that a future review-gate mod will be built on. If you install one mod before letting Claude Code anywhere near your pull requests, make it this one.
2. ccproxy — the foundation review automation will be built on
ccproxy by starbaser (★348, the most-starred mod project so far) hooks any request and modifies any response. It is not a review tool itself — it is the power tool you would build one with. Want a review flow where every diff passes through your team's policy check before the model sees it, or where responses get annotated with rule violations automatically? That is a ccproxy-shaped job. If you are the kind of engineer who builds their own tooling instead of waiting for it, start here.
3. The guard collections — hamzafer's and nateherkai's
hamzafer's collection ships guards alongside its live lines and panes, and nateherkai's four focused mods include a Collision Guard. Guards are the mod primitive that maps most directly onto review workflows: code that intercepts pipeline events and enforces rules. None of these are review-specific, but they are working examples of the pattern — study them if you want to write the first real review-gate mod yourself.
4. claude-kit — because review checklists are skills, not mods
Here is what most "best mods for X" lists get wrong: a code-review checklist is a skill, not a mod. Skills are markdown instructions that guide the model — "check for SQL injection, verify error handling, flag TODOs without issue links" — and claude-kit by JohnnyVizz ships public skills alongside its mods. For review quality today, a good checklist skill will do more for you than any mod on this page. The division of labor is simple: mods for the pipeline, skills for the judgment. Install both.
What a real code-review mod will look like
When it arrives, expect a guard that watches for diff-shaped events and does three things: annotates the diff inline before you read it, enforces team rules (no direct pushes to main, every PR touches a test), and redacts secrets first. Every building block exists — register subscribing to pipeline events, the $ API for drawing the annotations. Someone just has to assemble them. If that someone is you, tell us and we will list it.
