runcastle

An Opus planner triages your open `bug`-labelled GitHub issues into independent fixes, then a swarm of Sonnet fixers fans out — one per issue, each on its own branch — to reproduce, root-cause, patch, and test the bug in parallel.

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 Claude Code agent performs a refactor, a hard `npm test` gate proves nothing broke, then a Codex reviewer adversarially audits the change on the same warm branch — hunting regressions, weak tests, and shortcuts — fixing and looping until it approves.
