Prompt for your agent

Goal: Set up role-based agents with hard rules to ship a large feature safely.
Setup: agents used in source: Claude; tools/MCPs stated: GitHub Actions.
Steps:
1. Start from a single GitHub issue describing the ask.
2. A planning agent decomposes it into sub-issues with an explicit dependency graph.
3. Applying a label fires a GitHub workflow that loads a role-specific prompt (the agent acts as a hospital employee).
4. Encode rules in skills: no code before a plan, no plan without review.
5. Accept slower runs (even 10x) in exchange for well-tested, in-scope code.
Rules: ask me before anything irreversible (sending, posting, paying, deleting); don’t invent data, results or tools I haven’t given you; tell me what you couldn’t verify.
