runcastle

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.

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 mixed-provider copy pipeline: a Claude Code writer turns your product brief into full AIDA-structured landing page copy, then a Codex editor cuts fluff, makes claims concrete, and tightens headlines on the same warm branch, looping until it ships.

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 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.

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.
