Capture learnings, gotchas, and architectural decisions into the right project documentation while context is fresh. Use when capturing learnings, documenting gotchas, recording architectural decisions, or deciding where a piece of knowledge should live. Triggers on "document this", "remember this pattern", "what should I know about", or after completing significant features.

by citypaul

Behavior-driven UI testing patterns. Covers Vitest Browser Mode (preferred) and DOM Testing Library. Use when testing any front-end application, writing UI tests, querying DOM elements, or simulating user interactions. For React-specific patterns, see the react-testing skill.

by citypaul

Functional programming patterns with immutable data. Use when writing logic, data transformations, or encountering mutation bugs. Covers immutability violations catalog, pure functions, composition, early returns, and options objects. Do NOT over-apply heavy FP abstractions (monads, fp-ts) unless the project requires them.

by citypaul

Set up and run mutation testing with Stryker, including full-project and diff-against-main runs, then use surviving mutants to strengthen weak or missing tests. Use during the MUTATE phase of the TDD cycle, when verifying that tests actually catch bugs (coverage alone is not enough), when the user mentions mutation testing, Stryker, mutation score, or surviving mutants, or when assessing whether a test suite would detect realistic regressions. For writing the tests themselves, see testing.

by citypaul

Planning work as vertical slices or an explicitly selected mechanism-reduction program in small, known-good increments. Use when starting significant work, turning already-split stories into PR-sized implementation plans, planning PRs, or sequencing complex tasks. For a mechanism-reduction program, use reduce-system-complexity first to define the conserved contract, terminal mechanism-removal state, and behavior/mechanism gates; planning then sequences it. If the input is a broad story, epic, feature idea, or backlog item that still needs product slicing, use story-splitting first.

by citypaul

React component testing patterns including components, hooks, context, and forms. Covers Vitest Browser Mode with vitest-browser-react (preferred) and @testing-library/react. Use when testing React applications. For general UI testing patterns, see the front-end-testing skill.

by citypaul

Refactoring assessment and behavior-preserving patterns for code with a passing baseline and sufficient preservation evidence. Use when the user asks to clean up, simplify, or restructure a selected area, and after mutation testing or reviewed proportionate alternate evidence establishes confidence for the REFACTOR step. Covers commit-before-refactoring discipline, when refactoring adds value vs when to skip it, and priority classification. For any slice in a selected whole-path reduction program—transition or terminal—use reduce-system-complexity as the governing skill; refactoring may be secondary when applicable. For repository-wide architecture discovery use improve-codebase-architecture; for a module contract use codebase-design. Do NOT use for insufficiently evidenced code or adding behavior.

by citypaul

TypeScript strict mode patterns including schema-first development, branded types, type vs interface guidance, and tsconfig strict flags. Use when writing TypeScript code, defining types or schemas, or reviewing type safety. For immutability and pure function patterns, see the functional skill.

by ananddtyagi

Validate OpenAPI, Swagger, and GraphQL schemas match backend implementation. Detect breaking changes, generate TypeScript clients, and ensure API documentation stays synchronized.

Deterministic mathematical computation using SymPy. Use for ANY math operation requiring exact/verified results - basic arithmetic, algebra (simplify, expand, factor, solve equations), calculus (derivatives, integrals, limits, series), linear algebra (matrices, determinants, eigenvalues), trigonometry, number theory (primes, GCD/LCM, factorization), and statistics.
