測試與安全

Work with modern cryptographic primitives including AES, RSA, elliptic curves, and key derivation functions. Use this skill when implementing or breaking modern encryption schemes in CTF challenges.

WebAssembly runtime execution and instantiation. Use when running compiled WebAssembly modules, testing WASM execution, or interfacing with WASM instances from Python.

Implement Traveling Salesman Problem algorithms for route optimization. Use this skill when finding shortest routes through multiple points, solving pick path problems, implementing nearest neighbor or 2-opt algorithms, or optimizing travel sequences.

Rust testing patterns and best practices. Use this skill when writing, reviewing, or modifying Rust tests. Covers test organization, assertions with pretty_assertions, parameterized tests, and testing multiple input formats.

Graph algorithms for network analysis including shortest paths, cycle detection, and connectivity analysis. Create directed/undirected graphs with weighted edges. Use when modeling currency exchange networks, detecting arbitrage opportunities via negative cycles, finding optimal trading routes, calculating path lengths, analyzing network topology, or working with any connected data structures. Supports Bellman-Ford, Dijkstra, and other graph algorithms.

Comprehensive testing guidelines for Vitest and React Testing Library. Covers quality standards, AAA pattern, naming conventions, branch coverage, and best practices. Reference this skill when creating or updating test code during Phase 2 (Testing & Stories).

Algorithmic trading strategies and execution systems. Use for building trading bots, backtesting strategies, and implementing automated trading rules.

Guide for SELinux (Security-Enhanced Linux) security framework. Use when configuring mandatory access controls, troubleshooting permission denials, creating custom policies, or managing security contexts. Covers modes, contexts, booleans, and policy management.

Make HTTP requests to REST APIs with authentication, handle responses, and manage pagination. Use when connecting to external APIs, fetching data from CRM systems, syncing records between services, or implementing OAuth/API key authentication flows.

Comprehensive React component coding guidelines, refactoring principles, and architectural patterns. **CRITICAL**: Focuses on patterns AI commonly fails to implement correctly, especially testability, props control, and component responsibility separation. Reference this skill when implementing or refactoring React components during Phase 2.

Internationalization (i18n) and localization (l10n) testing for global products including translations, locale formats, RTL languages, and cultural appropriateness. Use when launching in new markets or building multi-language products.

Testing in production with feature flags, canary deployments, synthetic monitoring, and chaos engineering. Use when implementing production observability or progressive delivery.

Strategic test data generation, management, and privacy compliance. Use when creating test data, handling PII, ensuring GDPR/CCPA compliance, or scaling data generation for realistic testing scenarios.

Run tests using justfile tasks (just test-local for local development, just test-unit, just test-it). Use after implementing features, fixing bugs, when user mentions tests, validation, or before commits. Primary command is 'just test-local' which runs without external dependencies.

Measure quality effectively with actionable metrics. Use when establishing quality dashboards, defining KPIs, or evaluating test effectiveness.

Strategic regression testing with test selection, impact analysis, and continuous regression management. Use when verifying fixes don't break existing functionality, planning regression suites, or optimizing test execution for faster feedback.

Regulatory compliance testing for GDPR, CCPA, HIPAA, SOC2, PCI-DSS and industry-specific regulations. Use when ensuring legal compliance, preparing for audits, or handling sensitive data.

Conduct context-driven code reviews focusing on quality, testability, and maintainability. Use when reviewing code, providing feedback, or establishing review practices.

Test application performance, scalability, and resilience. Use when planning load testing, stress testing, or optimizing system performance.

Cross-browser, cross-platform, and cross-device compatibility testing ensuring consistent experience across environments. Use when validating browser support, testing responsive design, or ensuring platform compatibility.
