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.

runcastle

A single Claude Code agent turns an incident timeline and the last week of commit history into a blameless postmortem — summary, impact, timeline, root causes, contributing factors, what went well, and action items with owners and due dates — written to postmortem/POSTMORTEM.md.
