Module Index

Architecture

• system-design — Monolith vs microservices, service boundaries, CQRS
• bun-typescript — Bun runtime, TypeScript backend, FFI

API & Networks

• api-development — REST, controllers, validation, auth, error handling
• http-grpc — HTTP/gRPC protocols, versioning, idempotency
• graphql-api — Schema design, resolvers, N+1, subscriptions
• websocket-realtime — WebSocket, SSE, pub/sub, connection management

Frontend

• vue3-modernization — Composition API, Pinia, script setup
• state-management — Pinia, Vuex migration, reactive patterns

Performance & Resilience

• performance — Profiling, caching, lazy loading, bundle optimization
• fault-tolerance — Retry, circuit breaker, bulkhead, graceful degradation
• concurrency-async — Event loop, promises, workers, race conditions

Data

• sql-database — Schema design, indexing, migrations, query optimization

Operations

• monitoring-observability — Logging, metrics, tracing, alerting
• feature-flags — Progressive delivery, A/B testing, kill switches
• docker-containers — Docker, compose, multi-stage builds, health checks
• ci-cd-pipelines — GitHub Actions, GitLab CI, deployment strategies

Security

• security-auth — OWASP, JWT, OAuth2, rate limiting, input validation

Quality

• testing-fundamentals — Unit, integration, contract, E2E testing
• code-quality — Clean code, PR standards, refactoring patterns
• debugging — Cross-layer debugging, production RCA

Delivery

• scrum-agile — Sprint planning, story breakdown, estimation
• cross-functional — Tech specs, stakeholder communication
• feature-ownership — End-to-end delivery, release management

Standards

All code: clear, concise, performant, tested, observable, maintainable, backward-compatible.

Principles

1. Type safety first — no any
2. Fail fast — validate early, crash loudly
3. Readability > cleverness
4. Explicit > implicit
5. Design for change
6. Ship safely — feature flags, gradual rollout
7. Document decisions — ADR for architecture choices

Usage

1. Identify problem → auto-select module or specify module param
2. Load references/<module>/SKILL.md
3. Apply checklist
4. Validate against standards
