Claude Code Prompts

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.

Start Here

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.

Top 5 Outcome Scenarios

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

One Decision Tree + Token Budget

Use the single-source selector here: Prompt Selector Guide.

Rule: start minimal, then add exactly one specialist only if quality gates fail.

Active Agent Portfolio (Outcome-First)

claude-agent-system-prompt.md is the operational source of truth.

Prompt	Use when	Do not use when	File
Agent System ⭐	Any autonomous task	You only need a tiny cheat sheet	View
Quick Reference	Token budget is extremely tight	You need deep specialist logic	View
Code Review	Reviewing a PR/change set	Writing new feature code from scratch	View
Security Audit	Threat/risk exposure is possible	Task has no security relevance	View
Refactoring	Improving maintainability safely	Incident response under active outage	View
Testing	Building or fixing test strategy	You only need non-test docs	View
Documentation	Producing technical docs	You need runtime diagnosis	View
Performance	Latency/throughput/cost bottlenecks	Problem is primarily correctness	View
Git & VCS	Workflow, branching, commit hygiene	App logic decisions	View
Accessibility Audit	WCAG and accessibility compliance	Backend-only infrastructure change	View
Migration & Upgrade	Framework/runtime/DB migrations	Greenfield implementation	View
Monitoring & Observability	Logs, metrics, traces, alerts	Pure UI copy/content task	View
Debugging & Troubleshooting	Root-cause and incident diagnostics	You are designing architecture from zero	View
Claude Code Modes ⭐	Managing /think and planning depth	Non-Claude environments only	View
Claude Code Workflow	CLAUDE.md, hooks, permissions, MCP	You only need algorithm design	View
Technology Stack ⭐	Selecting tools/libraries	Stack is fixed and approved	View
Architecture Patterns	System design and trade-offs	Small local bug fix	View
Full-Stack Development	End-to-end app delivery	Single-layer scoped work	View
AI & LLM Integration	RAG/agents/model integration	No AI component exists	View
API Design & GraphQL	API contract/schema design	UI-only styling task	View
Cloud & Infrastructure	IaC/K8s/multi-region/cost	Local script-only changes	View
Data Engineering	Pipelines/streaming/data quality	CRUD app without data platform scope	View
Compliance & Governance	Regulated/security governance scope	Prototype with no compliance requirements	View
Multi-Agent Orchestration	Parallel agent coordination	Single-agent linear task	View
Monorepo & Complex Projects	Multi-package cross-cutting work	Small standalone repository	View
Error Handling & Resilience	Fault tolerance and degradation	Static content editing only	View
Developer Experience & Tooling	Linting/hooks/onboarding/DX	Feature logic changes only	View
Database Design & Optimization	Schema/index/query tuning	No persistent data layer exists	View
UI/UX & Design Systems	Design tokens/components/theming	API/backend-only task	View

Quality Gate (Repository Standard)

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

90-Day Improvement Cycle

Monthly: usage, token, and link hygiene review
Quarterly: keep/merge/archive portfolio review and active catalog cleanup
