Competitor Teardown & Positioning Brief
v1.0.1runcastle
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.
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.
Newsletter Digest Builder
v1.0.1runcastle
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.
