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 reads your offer and ideal-customer notes and writes a complete 5-touch cold email sequence — subject-line options, tight bodies, send timing, one clear CTA per email, and personalization tokens ready to merge at send time.

runcastle

A single Claude Code agent reads the commits since your last tag, groups them into Added/Changed/Fixed/Security by user-facing intent, and writes a clean CHANGELOG.md entry plus a friendly RELEASE_NOTES.md — turning raw git history into release-ready notes in one pass.
