PR review agent built by Colin McDonnell (creator of Zod). Runs inside GitHub Actions, dynamically scales effort to PR size, and goes beyond review with arbitrary tasks via `@pullfrog` mentions.

## Code review

- Dynamically scales effort
- Sub-30s reviews for small PRs
- Subagent swarms for large PRs
- Incrementally reviews new commits
- Maintains PR context across runs
- One-click Fix button on actionable reviews
- Auto-resolves addressed comments

## Beyond PR review

Tag `@pullfrog` in GitHub with arbitrary tasks or configure automations:

- Review new PRs
- Address human review
- Triage, reproduce, and label new issues
- Auto-fix CI failures and merge conflicts
- Custom cron tasks

## Batteries included

The agent harness ships with built-in MCP tools and skills:

- Git and GitHub operations
- Headless browser and screenshots
- Dependency auto-installation
- Repo-level learning and memory
- S3 and file upload

## Lifecycle hooks

Runs inside Actions and can invoke your repo's linter, test suite, and other scripts via `setup`, `post-checkout`, `pre-push`, and `post-run` hooks.

## Security

- Isolated shell tool — no secrets or git creds exposed to the agent
- GitHub tokens are run-scoped and auto-revoked
- Built-in branch protections, no pushes to main
- Secret auto-masking

## Billing

First 30 runs free, then 7¢/run plus model costs. Use Pullfrog Router (any model at cost, no markup), bring your own key, or a Claude Code subscription.
