20 markdown templates for people building agent and automation products: product specs, system prompt templates, eval checklists, runbooks, onboarding docs, changelog formats, pricing page copy, and support macros. Every template uses [BRACKETED] placeholders: search for "[" and fill as you go. Sections come pre-structured: behavior, edge cases, failure modes, acceptance criteria, refusal lines, refund policy lines. You answer the questions; the structure is done. The pack covers the paperwork that agent products skip: the v1 spec (3 templates), the prompt that grew by accretion (4 prompt templates with boundaries and examples), the release nobody documented (2 changelog/release templates), the incident that repeated because no runbook existed (2 templates), the user who never finished setup (2 onboarding templates), the pricing page that lists features instead of outcomes (2 copy skeletons), and the support inbox at 1am (2 macro sets). Plain markdown. No tooling, no platform lock-in: any editor, docs tool, or repo works. Use them in your own products, including products you sell. No assumptions about your stack or model: these templates structure decisions and documents, the technical content stays yours. Includes index.md mapping all 20 templates to the moment you need each one. Personal + commercial license. No resale or redistribution of the files as-is.
