Browse reusable Agent Skills, each with a clear purpose and practical guidance.
Validates all code changes before committing by running format, lint, type, and unit test checks. Use after making backend (Python) or frontend (TypeScript) changes, before committing or finishing a work session.
Runs Python unit tests with coverage, analyzes coverage reports, and implements meaningful tests to increase coverage by ~0.2%. Use when you want to systematically improve Python test coverage with high-value test cases.
Explains Streamlit's internal architecture including backend runtime, frontend rendering, and WebSocket communication. Use when debugging cross-layer issues, understanding how features work end-to-end, planning architectural changes, or onboarding to the codebase. Covers ForwardMsg/BackMsg protocol, script rerun model, element tree, widget state management, and more.
Diagnose and fix flaky Playwright e2e tests. Use when tests fail intermittently, show timeout errors, have snapshot mismatches, or exhibit browser-specific failures.
Evaluates comments, docstrings, and naming in code for readability by a developer new to the codebase — is the documentation clear and concise, and is non-obvious logic documented? Produces findings with concrete proposed rewrites (or additions where documentation is missing); the caller decides whether to apply them or present them as feedback. Use when reviewing a PR, branch, or set of changes for comment quality, naming clarity, or documentation readability. For a PR's title and description, use reviewing-pr-description instead.
Use when adding, modifying, or reviewing E2E test apps/skeletons to keep the test coverage report up to date.
Trace bugs through call chains using knowledge graph
Scan Logseq ClojureScript Node/Electron targets for npm module loading risks, especially ESM-only packages that may fail when loaded through js/require or shadow-cljs require-based shims. Use when changing Electron/main-process dependencies, debugging startup import errors, or auditing packages before dependency upgrades.
Debug Logseq bugs with the right runtime, concrete before/after evidence, and end-to-end reproduction steps.
