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 single Claude Code agent brings your dependencies up to date in safe batches — patches, then minors, then one major at a time — fixing any breakage it introduces, gated by a hard build + test check every round until everything is current and green.

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

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.
