runcastle

A single Claude Code agent that finds the least-tested modules in your repo, writes focused unit tests for them one module at a time, and verifies the suite stays green after every batch — stopping once it hits your coverage target.

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 Claude Code agent performs a refactor, a hard `npm test` gate proves nothing broke, then a Codex reviewer adversarially audits the change on the same warm branch — hunting regressions, weak tests, and shortcuts — fixing and looping until it approves.

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 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.

runcastle

Fans out a searcher per sub-question to fetch and note public web sources, then an Opus synthesizer writes a fully cited report, then a Codex fact-checker adversarially verifies every claim against the notes and loops until the report holds up.

runcastle

Fetches a single target page and audits its on-page SEO — title, meta, headings, canonical, Open Graph, structured data, alt text, internal links, word count — then writes a prioritized, fix-by-fix action list you can hand to a developer.
