## How It Works
Ralph Review now uses a batch-first workflow:
1. `rr run` performs review only.
2. The reviewer runs in a disposable session worktree and reports structured findings.
3. Findings are deduplicated across review iterations and persisted as a session artifact.
4. If findings exist, you choose which ones to fix with `rr fix`.
5. The fixer handles the selected findings in a separate batch remediation phase.
6. Resolved fixes are handed back to your working tree, either automatically or as a pending handoff
to apply manually.
This keeps review and remediation separate by default. The reviewer can focus on finding real
issues, and the fixer treats those findings as input for a later, explicit remediation step.
Use `rr run --auto` when you want Ralph Review to run remediation immediately after review. Add
`--priority P0,P1` to auto-fix only selected priority levels.

```
### Reviewer
The reviewer analyzes the selected review scope for correctness, security, reliability, and
maintainability issues introduced by the change. It outputs structured findings with stable IDs
such as `F001`, priorities `P0` through `P3`, and source locations.
Reviewer iterations continue until no new findings are discovered or `maxIterations` is reached.
By default the run stops early when an iteration finds nothing new. Use `--force` to run the full
iteration count.
### Fixer
The fixer runs only after findings have been persisted and selected. It receives the selected
finding inventory, works in a disposable fix worktree, and returns a per-finding result:
`resolved` or `unresolved`.
When all selected findings are resolved, Ralph Review creates a handoff. Depending on the working
tree state, the handoff may be applied automatically or left pending for `rr apply`. If selected
findings remain unresolved, Ralph Review keeps the remediation worktree available for inspection.
---
## Workflows
Ralph Review fits into a few common loops. Each workflow below shows the scenario
first, then the exact commands.
### 1. Review what you are about to commit
You just finished a feature on a working branch. Before you stage and push, you
want a second pair of eyes on staged, unstaged, and untracked changes.
```bash
rr run --uncommitted
```
Findings are printed and persisted. You can keep coding while the reviewer runs
in the background and come back to triage when it is done.
### 2. Review your branch against the base
You are preparing a pull request against `main` and want the reviewer to look at
the full diff, not just your last commit.
```bash
rr run --base main
```
Add a focus instruction when the diff is large:
```bash
rr run --base main "focus on auth boundaries and input validation"
```
### 3. Re-review a single commit
CI flagged something on a specific commit, or you are auditing a hotfix in
isolation.
```bash
rr run --commit 9f3a2b1
```
### 4. Review now, fix later (the default loop)
`rr run` only reviews. Findings get a stable ID (`F001`, `F002`, ...) and a
priority (`P0` through `P3`). Triage them, then fix exactly what you want:
```bash
rr run
rr fix --session SESSION --priority P0,P1
# or pick by ID
rr fix --session SESSION --id F003 --id F007
```
When the fixer is done it either applies the patch to your working tree
automatically, or leaves a pending handoff that you apply explicitly:
```bash
rr apply
```
### 5. Review and auto-fix in one shot
Trusted change, low risk, you want the loop to close itself:
```bash
rr run --auto --priority P0,P1
```
The reviewer runs first, then the fixer immediately remediates only matching
priorities in a disposable worktree and hands the result back to you.
> Auto Setup picks the reviewer model based on Factory.ai's public code review
> benchmark. See [Why these models?](#why-these-models-auto-setup-model-selection)
> below.
### 6. Pre-PR / team review workflow
Before opening a PR, run a base-branch review and let auto-fix clean up the
obvious stuff. Anything left becomes review notes you can paste into the PR
description.
```bash
rr run --base main --auto --priority P0
rr log -n 1 # grab the latest review log
rr log --json # or pipe into your own tooling
```
For an org-wide loop, persisted review logs (`rr log --json --global`) make it
easy to feed findings into dashboards or follow-up issues.
### 7. Triage with Interactive Mode
Run `rr` with no arguments to open Interactive Mode. It shows active sessions,
recent history, review output, findings, fix results, and handoff status in a
single view, which is convenient when several reviews are in flight.
### Why these models? (Auto Setup model selection)
`rr init` with Auto Setup chooses your reviewer and fixer's model. That list is
informed by Factory.ai's public code review benchmark, which scored 13 frontier
and open-weight models against a golden set of 50 human-curated bugs across
five real-world repositories (Sentry, Grafana, Keycloak, Discourse, and
cal.com).
The reviewer model priority (highest first) is currently:
1. GPT-5.2
2. Claude Opus 4.6
3. Claude Sonnet 4.6
4. Claude Opus 4.7
5. GLM 5.1
6. GPT-5.3 Codex
7. Gemini 3.1 Pro Preview
8. Kimi K2.6
Models near the top scored highest on the benchmark for finding real bugs at a
reasonable cost. The fixer priority is tuned separately and favors models that
are strong at code edits rather than at finding issues.
For the methodology and full results, see Factory.ai's writeup:
[Which Model Reviews Code Best?](https://factory.ai/news/code-review-benchmark).
You can always override the auto selection by running `rr init` and choosing
Customize Setup, or by editing `reviewer.model` and `fixer.model` in your
configuration directly.

## Prerequisites
- [Bun](https://bun.sh) (runtime)
- [tmux](https://github.com/tmux/tmux) (background sessions)
- At least one [supported agent CLI](#supported-coding-agents) installed and authenticated
Ralph Review is a Bun-only TypeScript CLI. Use Bun for development and script execution.
---
## Installation
```bash
# Homebrew (install or update)
brew install kenryu42/tap/ralph-review
# npm (install or update)
npm install -g ralph-review
# Or let Ralph Review detect the install method and update itself
rr update
```
For update checks without installing, run:
```bash
rr update --check
```
If install-source detection is ambiguous, force the package manager:
```bash
rr update --manager npm
rr update --manager brew
```
---
## Quick Start
```bash
# Configure reviewer and fixer agents
rr init
# Start Interactive Mode
rr
# Start a review-only background session
rr run
# Review against a base branch
rr run --base main
# Review staged, unstaged, and untracked changes
rr run --uncommitted
# Review a specific commit
rr run --commit SHA
# Fix findings after review completes
rr fix --session SESSION_ID --all
# Review and immediately fix P0/P1 findings
rr run --auto --priority P0,P1
```
`rrr` is a shorthand alias for `rr run`. It starts a non-interactive review run without launching
Interactive Mode.

## Supported Coding Agents
| Agent | Link |
|-------|------|
| Claude Code | https://code.claude.com/docs/en/overview |
| Codex | https://openai.com/codex/ |
| Droid | https://factory.ai/ |
| Gemini CLI | https://geminicli.com/ |
| OpenCode | https://opencode.ai/ |
| Pi | https://pi.dev |
You can assign different agents and models to the reviewer and fixer roles. For example, Codex can
review while Claude or Gemini fixes.

## Configuration
Run `rr init` to create configuration. Ralph Review supports a user-global config and repo-local
overrides:
- Global config: `~/.config/ralph-review/config.json`
- Repo-local overrides: `.ralph-review/config.json`
By default, `rr config show` displays the effective merged configuration for the current project.
```bash
# View effective configuration
rr config show
# View raw JSON
rr config show --json
# View only repo-local overrides
rr config show --local
# View one value
rr config get reviewer.agent
# Update global configuration
rr config set maxIterations 8
# Update repo-local configuration
rr config set --local defaultReview.branch main
# Edit configuration in $EDITOR
rr config edit
rr config edit --local
```
Useful settings include:
| Key | Purpose |
|-----|---------|
| `reviewer` | Agent, model, and reasoning used for review |
| `fixer` | Agent, model, and reasoning used for remediation |
| `maxIterations` | Maximum reviewer iterations per run |
| `iterationTimeout` | Per-agent timeout in milliseconds |
| `defaultReview` | Default review target, such as uncommitted changes or a base branch |
| `notifications.sound.enabled` | Completion sound preference |
Run `rr doctor` to verify that your environment and configuration are valid. Add `--fix` to let it
auto-resolve supported issues.
