runcastle

A single Claude Code agent that finds the least-tested modules in your repo, writes focused unit tests for them one module at a time, and verifies the suite stays green after every batch — stopping once it hits your coverage target.

runcastle

A single Claude Code agent brings your dependencies up to date in safe batches — patches, then minors, then one major at a time — fixing any breakage it introduces, gated by a hard build + test check every round until everything is current and green.

runcastle

A single Claude Code agent reads your repository — a shell-expanded file map seeds it, and it can install and run the project — then writes and incrementally commits a real `docs/` set: a getting-started guide, an architecture overview, and per-module reference pages.

runcastle

A Claude Code writer drafts an X/Twitter launch thread from your product brief, then a Codex critic tears it apart post-by-post — hook, clarity, specificity, CTA — rewriting the weak posts on the same warm branch until the thread is ready to ship.
