Systematic debugging methods, log analysis, and performance diagnostics. Use when debugging issues, analyzing errors, or troubleshooting incidents.
Security review skill: comprehensive security checklist and patterns. Use when adding authentication, handling user input, working with secrets, or creating API endpoints.
Testing strategies and methodologies including TDD and E2E testing. Use when writing tests, implementing TDD workflow, or setting up E2E test infrastructure.
DevOps patterns: containerization, CI/CD, deployment strategies, monitoring. Use when containerizing apps, setting up pipelines, or deploying services.
Code quality assurance strategies. Parent skill for quality-related skills: security (security review) and debug (systematic debugging).
Strategic compaction skill: suggests context compression at logical breakpoints. Use to suggest compaction at logical intervals during development sessions.
Session lifecycle management. Parent skill for session-related skills: learning (pattern extraction) and compact (context compression).
Frontend patterns: component design, state management, performance, accessibility. Use when building web frontends, components, or client-side apps.
Database design, query optimization, migrations, and indexing. Use when designing schemas, writing queries, or managing migrations.
Extracts reusable patterns from sessions. Use at session end to capture debugging insights and project-specific knowledge.
Code exploration strategies for understanding unfamiliar codebases. Use when exploring unknown code, debugging, or analyzing architecture.
Architecture design skill: ADR records, system design checklists, scalability assessment, architecture patterns. Use for complex system design and architecture decisions.
Backend development patterns for services, error handling, logging, caching. Use when building backend services, APIs, or microservices.
RESTful API design patterns and best practices. Use when creating endpoints, designing APIs, or implementing routes.
Cross-validate code, architecture or design decisions using a second model. Use for critical decisions, complex refactoring, security reviews.
Spec-driven development workflow. Interactive phase-by-phase confirmation from proposal to implementation. Trigger: 'spec-flow', 'spec mode', 'need a plan', 'structured development', 'write a spec', 'feature spec', 'technical spec', '需求文档', '技术方案', '任务拆解', '规格驱动', '写个方案', '做个规划', '结构化开发', 'plan this feature', 'break this down', 'design doc'. Creates .spec-flow/ directory with proposal, requirements, design, and tasks.
Track and analyze US government shutdown liquidity impacts by monitoring TGA (Treasury General Account), bank reserves, EFFR, and SOFR data from FRED API. Use when user wants to (1) analyze current or past government shutdown effects on financial markets, (2) track liquidity conditions during fiscal policy disruptions, (3) assess "stealth tightening" effects, (4) compare shutdown episodes across different monetary policy regimes (QE vs QT), or (5) generate liquidity stress reports with historical context. Recommended usage frequency is weekly on Wednesdays after TGA/reserve data releases.
