Systematic methodology for debugging bugs, test failures, and unexpected behavior. Use when encountering any technical issue before proposing fixes. Covers root cause investigation, pattern analysis, hypothesis testing, and fix implementation. Use ESPECIALLY when under time pressure, "just one quick fix" seems obvious, or you've already tried multiple fixes. NOT for exploratory code reading.
Transform raw data into analytical assets using ETL/ELT patterns, SQL (dbt), Python (pandas/polars/PySpark), and orchestration (Airflow). Use when building data pipelines, implementing incremental models, migrating from pandas to polars, or orchestrating multi-step transformations with testing and quality checks.
Comprehensive test automation specialist covering unit, integration, and E2E testing strategies. Expert in Jest, Vitest, Playwright, Cypress, pytest, and modern testing frameworks. Guides test pyramid design, coverage optimization, flaky test detection, and CI/CD integration. Activate on 'test strategy', 'unit tests', 'integration tests', 'E2E testing', 'test coverage', 'flaky tests', 'mocking', 'test fixtures', 'TDD', 'BDD', 'test automation'. NOT for manual QA processes, load/performance testing (use performance-engineer), or security testing (use security-auditor).
Role of Web Security Testing and Penetration Engineer, focusing on JavaScript reverse engineering and browser security research. Trigger scenarios: (1) JS reverse analysis: identification of encryption algorithms (SM2/SM3/SM4/AES/RSA), obfuscated code restoration, Cookie anti-crawling bypass, WASM reverse engineering (2) Browser debugging: XHR breakpoints, event listening, infinite debugger bypass, Source Map restoration (3) Hook technology: writing XHR/Header/Cookie/JSON/WebSocket/Canvas Hooks (4) Security product analysis: Offensive and defensive analysis of JS security products such as Ruishu, Jiasule, Chuangyudun, etc. (5) Legal scenarios such as CTF competitions, authorized penetration testing, security research, etc.
Build and test Solidity smart contracts with Foundry toolkit. Use when developing Ethereum contracts, writing Forge tests, deploying with scripts, or debugging with Cast/Anvil. Triggers on Foundry commands (forge, cast, anvil), Solidity testing, smart contract development, or files like foundry.toml, *.t.sol, *.s.sol.
Comprehensive toolkit for validating, linting, and testing GitHub Actions workflow files, custom local actions, and public actions. Use this skill when working with GitHub Actions YAML files (.github/workflows/*.yml), validating workflow syntax, testing workflow execution with act, or debugging workflow issues.
Cypress end-to-end testing for web apps. Use for E2E testing.
pytest-django testing patterns, Factory Boy, fixtures, and TDD workflow. Use when writing tests, creating test factories, or following TDD red-green-refactor cycle.
pytest Python testing framework with fixtures. Use for Python testing.
