custom-linter-creator
A skill to create custom lint rules by leveraging each programming language's existing linter ecosystem. This is a linter intended for AI agents rather than humans: error messages are designed to act as fix-instruction prompts for an AI. Create custom rules in the lints/ directory using the standard per-language methods (e.g., Rust (dylint), TypeScript/JavaScript (ESLint), Python (pylint), Go (golangci-lint)). Use cases: (1) when you want to force project-specific coding rules on an AI, (2) when you want lint rules that output AI-readable fix instructions on violation, (3) when you want to enforce naming conventions, structural patterns, or consistency rules via AI-driven linting. Triggers: "create a linter rule", "add a lint rule", "enforce this pattern", "AI linter", "custom lint", "code rules", "naming rule", "structure rule".

CI Log Interpretation
Knowledge for interpreting CI failure logs from GitHub Actions. Covers PHPUnit, PHPStan, ECS, ESLint, TypeScript, Stylelint, Prettier, Jest, Playwright, ludtwig, and Lighthouse. Use this skill whenever reading CI logs, diagnosing why a CI check failed, analyzing GitHub Actions job output, debugging a red build, or when the user asks "why did CI fail", "what broke the build", "check the pipeline", or shares log output that contains tool errors. Also use when fetching or reviewing run logs, job logs, or check annotations from GitHub Actions, even if the user does not explicitly mention "CI" — any interaction with GitHub Actions failure output benefits from this skill's noise-filtering and tool-identification knowledge.
