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.

runcastle

A single Claude Code agent turns an incident timeline and the last week of commit history into a blameless postmortem — summary, impact, timeline, root causes, contributing factors, what went well, and action items with owners and due dates — written to postmortem/POSTMORTEM.md.
