Writing a good AGENTS.md
Reference AGENTS.md files plus prompts that pair well with them.
- Workspine
A repo-native delivery spine that keeps AI-assisted work consistent across sessions, agents, and cold starts.
- reddit-post-builder: turn real work into a post that survives r/ClaudeCode
Refuses to write generic listicles. Interviews you for the actual work, picks the right sub (r/ClaudeCode, r/codex, r/cursor, etc.), tunes the voice, then stress-tests the draft against the skeptical-regular and corporate-voice failure modes.
- last-30-days: catch yourself up on any topic in a grounded markdown brief
Synthesizes official sources, news, and community discussion from a recent window into a dated brief on what actually changed and what people are arguing about — not a Wikipedia summary.
- commit-archeologist: figure out why any line of code exists
Walks git blame back through every rewrite, follows each commit to its PR, the PR to its issue, and the issue to the original Slack/Linear thread — answers "why does this code exist?"
- Workflow Contract for AI-Driven Repos
Non-negotiables for shipping safely when parallel agents share one repo and a live user base — pre-flight, branch hygiene, live-site rules.
- Modern Indie SaaS Architecture (2026)
Default stack: Next.js + Supabase + Vercel + Resend, with the request flow drawn out
- Production Incident Response Runbook
First 15 minutes when a production alert fires — acknowledge, triage, decide, communicate
- Mom Test User Interview Script
30-min user interview guide that gets past politeness to real signal
