PR Description Writer
v1.0.1runcastle
A single Claude Code agent reads the diff and commit history of your branch against its base, then writes a complete, reviewer-ready PR_DESCRIPTION.md — summary, what changed, why, testing, risk, and a reviewer checklist — grounded entirely in the real diff.
Launch Thread Writer + Critic
v1.0.1runcastle
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.
Incident Postmortem Writer
v1.0.1runcastle
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.
Release Notes Writer
v1.0.1runcastle
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.
