Production-ready prompt library for Claude AI and coding agents, built on the APEI cycle: Analyze → Plan → Execute → Iterate.
Repository default is English-only and remains enforced to keep quality, tone, and contribution standards consistent across all prompts.
- Open REPOSITORY-MAP.md for one-file navigation.
- Use Agent System as the core prompt.
- Add one specialist prompt only when the task clearly needs it.
- Validate outputs against explicit success criteria.
| Scenario | Prompt Setup |
|---|---|
| General autonomous coding | Agent System |
| Debugging production issues | Agent System + Debugging & Troubleshooting |
| Security-sensitive changes | Agent System + Security Audit |
| Architecture decisions | Agent System + Architecture Patterns |
| Complex multi-agent execution | Agent System + Multi-Agent Orchestration |
Use the single-source selector here: Prompt Selector Guide.
Rule: start minimal, then add exactly one specialist only if quality gates fail.
claude-agent-system-prompt.mdis the operational source of truth.

Every active prompt must include:
## Role## Protocol / Core Loop## Phases## Remember(final section)
And must follow No Vague Advice:
- each recommendation must end with a concrete decision, tool, or validation step.
Use the measurable review checklist: Prompt Review Checklist
- Monthly: usage, token, and link hygiene review
- Quarterly: keep/merge/archive portfolio review and active catalog cleanup
