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.

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.
