# review-all

Runs up to ten review agents on your diff, then a separate verifier tries to knock down every finding. Useful before a merge or a commit.

## What it does

The plugin adds a `/review-all` slash command. A script first maps the toolchain and test layout, then typecheck, lint and scoped tests run in parallel. A failing step turns into a finding, and its output is handed to the agents alongside the diff.

Two more scripts choose the files and the review axes. Binaries, secrets and generated code are dropped before any agent starts. Six axes always run; four more switch on only when the diff has matching files. Each agent sees the diff in its own order and gets rule packs for its language. Findings are then grouped by root cause, and a verifier on Haiku attempts to disprove each one. A behaviour claim needs a quoted source line to survive.

You need Claude, `git`, `bash` and `python3`. Without `gh` there is no `PR #N` target and no posting to a pull request. In `gate` mode the plugin writes `gate-verdict.json` and exits with `0` for pass, `1` for blocked, `2` for a malformed verdict. Only 🔴 findings block by default; `--severity important` adds 🟠. If any agent fails to answer, the gate fails.

## 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 review-all@claude-community
```

## When to use it
- run typecheck, lint and tests on the diff before merging
- find behaviour and security defects without reading every changed line by hand
- filter out false positives with a verification pass
- block a CI change that carries a critical finding
- resume an interrupted review from saved checkpoints

## Example prompts
- /review-all
- /review-all PR #123
- /review-all gate --severity important

Multi-agent code review for [Claude Code](https://code.claude.com/docs/en/overview), for any language or stack. It runs the repo's own typecheck/lint/tests, has up to ten review agents read the diff in parallel, then has a separate verifier re-check every finding before it reaches the report.

## Install

```
/plugin marketplace add ncoevoet/claude-review-all
/plugin install review-all@ncoevoet-review-all
```

Or, to hack on the skill: `git clone` this repo and run `make install`, which copies `skills/review-all/` to `~/.claude/skills/review-all/` (`make uninstall` removes it).

Requires Claude Code, `git`, `bash`, `python3`. `gh` is optional: it is used for `PR #N` targets and for the post-to-PR / create-issue actions.

## Use

| Argument | Reviews |
|---|---|
| _(empty)_ | Uncommitted changes, else current branch vs default branch, else last commit |
| `--staged` / `--unstaged` | Only staged / unstaged changes |
| `last commit`, `last N commits` | `HEAD~N..HEAD` |
| `vs <branch>` | Current branch vs merge-base with `<branch>` |
| `<sha1>..<sha2>` | A commit range |
| `PR #N` or `#N` | A GitHub PR (needs `gh`) |
| _file paths_, `--paths a,b`, `--exclude x,y` | Narrow the diff to / away from these paths |
| `gate` / `--ci` | Headless mode: JSON verdict and exit code, no menu (see [Gate mode](#gate-mode-ci)) |

```

## How it works

1. **Discover.** One script (`scripts/discover.sh`) detects the toolchain, test layout and available tools. Rules extracted from `CLAUDE.md` are cached; toolchain data is re-probed every run.
2. **Deterministic gates.** Typecheck, lint and scoped tests run in parallel. New public code without a test is flagged. A failing gate becomes a finding directly, and its output is passed to the agents as a `<gate_results>` block.
3. **Select files and agents.** `select-files.py` drops binaries, secrets, generated/vendor output and oversized files before any agent runs. `select-agents.py` picks the axes: six always run; security deep-dive, test-quality, API-contract and a11y/i18n run only when the diff contains matching files. Skipped axes are named in the report.
4. **Review in parallel.** Axes: standards, bugs+security, DRY, consistency, simplification, security deep-dive, performance, test quality, API contract, a11y/i18n. Every spawn names its model: `opus` for behavioral axes (bugs, security, performance, API contract) and `sonnet` for the others. Each agent gets the diff in its own file order (`agent-order.py`), plus per-language rule packs from `rules/`. Completed axes are saved to `.claude/review-all/checkpoints/`, so an interrupted run picks up where it stopped.
5. **Dedupe and verify.** Findings are grouped by root cause (the report says "Flagged independently by N agents"). Then a verifier (Haiku by default) tries to disprove each one: a behavior claim has to be backed by a quoted source line. Findings scoring ≥75 go in the report, 50–74 in the appendix, and the rest are dropped.
6. **Claim classes.** A runtime, data or rendering claim that is backed only by reading the source gets the `unverified` verdict. It is shown in its own section with the observation that would settle it, and it never blocks a gate.
7. **Report.** It opens with a verdict line, then gate results with a **Provenance** column (command, exit code, time), then findings by severity. It ends with a machine-readable `<!-- review-all-severity: {…} -->` tally.
