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 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

Reads a links.md list of URLs, fetches each one inside the sandbox, and has a Claude Code agent write a ready-to-send newsletter digest — a tight 2–3 sentence summary of every link, why it matters to your readers, and the source link, all assembled into a single markdown issue.
