# claude-deep-review

A Claude plugin that runs your changes past several specialist reviewers and verifies each finding before you see it.

## What it does

The plugin fans out parallel agents, each with its own focus: bugs, security, tests, cross-file impact, project conventions, type design and simplification. Findings then go through merging, fact checking, a skeptical validator and a blind challenge, where a fresh agent re-examines the claim without the original reasoning. Anything that fails gets dropped or downgraded to a suggestion.

Reports land in `.code-gauntlet/`, and the plugin asks before posting inline comments. You need Claude 2.1.154 or newer, git, Python 3.10 or newer available as `python3`, `python` or `py -3`, plus an authenticated `gh` for GitHub or `glab` for GitLab. On Windows, Git for Windows supplies the Bash tool Claude relies on; local-changes reviews have been run live there, while PR reviews are covered only by CI tests so far.

The review agents' models are pinned inside the pipeline, so your session's model and effort level leave them alone. Project rules, confidence thresholds and ignored findings live in `REVIEW.md`, which is optional. Code under review is treated as untrusted input, and prompt-injection attempts get filtered.

## Install

### Claude Code (native platform)

**Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add anthropics/claude-plugins-community
```
In the agent chat (not a shell):
```text
/plugin install claude-deep-review@claude-community
```

## When to use it
- run a PR past several specialist reviewers at once
- weed out false findings before comments go up
- tell new problems apart from older ones your changes exposed
- check whether changed paths have test coverage
- set confidence thresholds and an ignore list in `REVIEW.md`

## Example prompts
- Run code gauntlet on PR #42
- Give MR !89 a thorough review
- Review my uncommitted changes

# Code Gauntlet

Adversarial code review for Claude Code: each GitHub PR or GitLab MR runs a gauntlet of up to seven specialist agents for bugs, security, tests and cross-file impact, and every finding must survive verification, a skeptical validator, and a blind challenge before it is posted.

## Quick start

```bash
claude plugin marketplace add https://github.com/liatrio-labs/claude-code-gauntlet.git
claude plugin install code-gauntlet@code-gauntlet
```

Update later with `claude plugin update code-gauntlet@code-gauntlet`.

Run `/code-gauntlet 42` in your repository to review PR #42.
The plugin saves a markdown report under `.code-gauntlet/` and asks before posting inline comments.

Plain words work too, because the plugin triggers on code review requests:

```text
code gauntlet PR #42                  # GitHub pull request
review MR !89 thoroughly              # GitLab merge request
comprehensive review of my changes    # local uncommitted changes
```

The plugin detects GitHub or GitLab from the git remote.
You need Claude Code 2.1.154 or newer, git, Python 3.10 or newer reachable as `python3`, `python`, or `py -3`, and an authenticated `gh` (GitHub) or `glab` (GitLab).
Native Windows is supported with Git for Windows installed, which gives Claude Code its Bash tool.
A live headless run on Windows verifies local-changes reviews; PR reviews on Windows are covered by
Windows CI tests, not yet by a live forge review.

There is nothing to `pip install`.

The pipeline pins the review agents' models, so your own session's model and effort do not change them.
We recommend Sonnet at low effort for that session.

Historical full reviews took 16 to 22 minutes per PR in our [benchmark runs](bench/MEASUREMENT.md#ledger-sourced-costs).
The v3.0 measurement used 20.9 million tokens across 15 PRs, about 1.4 million per PR ([results](#benchmark-results)).

## How it reviews

A full review runs seven discovery agents in parallel:

| Agent | Model | Focus |
| --- | --- | --- |
| bug-detector | Sonnet | Logic errors, edge cases, error handling, resource leaks |
| security-reviewer | Opus | Injection, authentication, data flows, vulnerabilities |
| cross-file-impact | Sonnet | Callers and dependencies across the codebase |
| test-analyzer | Sonnet | Missing tests, weak assertions, untested paths |
| conventions-and-intent | Sonnet | Project rules, specs, comment accuracy |
| type-design-analyzer | Sonnet | Type boundaries and invariants |
| code-simplifier | Sonnet | Simplification opportunities |

The security reviewer runs on Opus, a judgment call that the [routing research](docs/research/artifacts/12-model-routing-for-code-review.md) explains.
When every changed file is low risk and the change is under 50 lines, the plugin offers a light review with only `bug-detector` and `security-reviewer`.

Discovery produces candidates, and each one then runs the gauntlet:

1. Merge combines duplicate findings and checks their structure.
2. Verify checks source facts and separates new issues from older ones.
3. Validate asks an independent skeptic to disprove each finding.
4. Filter applies confidence thresholds, rejects prompt injection, and groups related findings.
5. Blind challenge asks a fresh agent to check the claim without the original reasoning or evidence.
