fitness-functions
From the author
Write architecture fitness functions — deterministic tests that enforce a project's hard rules (module boundaries, offline guarantees, content contracts) from inside its own test target. Use when a constraint lives only in prose (CLAUDE.md, code review) and should become un-arguable.

- writing-unit-testsjaktestowac/awesome-copilot-for-testersWrites and reviews focused, deterministic unit tests that verify behavior through public interfaces instead of implementation details. Use whenever tests are added to code that already exists, and when the request mentions unit tests, test coverage, edge cases, mocks or test doubles, "add tests for this function", "cover this module", "these tests are flaky", or "this test breaks every refactor". Also use when reviewing an existing suite for brittleness, weak assertions, or missing boundary cases.Testing★ 119

- build-featureDoist/todoist-cliBuilds a new command, flag or behaviour in thin test-first slices, after settling the open decisions with the owner. Use when asked to "add", "build", "implement", "support" or "create" something, such as a new command, subcommand or flag.Testing★ 330
