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

Fans out an analyst agent per competitor to fetch and dissect each rival's site — pricing, positioning, messaging, gaps — then a strategist synthesizes the teardowns into a single positioning brief with sharp, defensible angles for your product.

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

Turn a single topic into a publish-ready blog post through three sequential Claude Code passes on one warm branch: an Opus strategist outlines the angle and keywords, a Sonnet writer drafts the full post, and an Opus editor tightens the prose and optimises it for search.
