Apply this project's coding standards to any TypeScript/JavaScript code you write, refactor, or review. Use this skill WHENEVER you create or change application code — new functions, endpoints, components, bug fixes, refactors — or whenever the user asks to clean up, refactor, simplify, or review code for style, even if they don't mention "standards" or "style" by name. Triggers include: "refactor this", "clean this up", "is this well written?", "review my code", writing any new method/class/module, or anything touching files under src/ or frontend/. This skill encodes the project's rules on method length, parameters, variable scope, error handling, comments, magic numbers, nesting, and ternaries so new code matches the rest of the codebase instead of drifting.

Write and organize automated tests for this project following its established conventions (Vitest + Sinon for unit/integration, Playwright for E2E). Use this skill WHENEVER you create or change application code that needs test coverage, or whenever the user asks to write, add, fix, or review tests — even if they don't mention Vitest, Sinon, or Playwright by name. Triggers include: "add a test", "cover this with tests", "write a unit/integration/e2e test", "is this tested?", new functions/endpoints/components, bug fixes that need a regression test, or anything touching files under test/ or e2e/. This skill encodes where tests live, the tooling, the structure, and the coverage targets so new tests match the rest of the codebase instead of drifting.
