runcastle

A single Claude Code agent reads your product and segment notes, then produces a defensible TAM/SAM/SOM estimate using both top-down and bottom-up methods — every assumption stated, a sensitivity table, and honest caveats — written to research/market-sizing.md.

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

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.
