--- name: symfony:tdd-with-phpunit description: Apply RED-GREEN-REFACTOR with PHPUnit 10/11 for Symfony; KernelTestCase/WebTestCase, attributes (#[Test]/#[DataProvider]), Foundry license: MIT --- # Tdd With Phpunit (Symfony) ## Use when - Building regression-safe behavior with TDD/functional/e2e tests. - Converting bug reports into executable failing tests. ## Default workflow 1. Write failing test for target behavior and one boundary case. 2. Implement minimal code to pass. 3. Refactor while preserving green suite. 4. Broaden coverage for invalid/unauthorized/not-found paths. ## Guardrails - Prefer deterministic fixtures/builders. - Assert observable behavior, not internal implementation. - Keep tests isolated and stable in CI. ## Progressive disclosure - Use this file for execution posture and risk controls. - Open references when deep implementation details are needed. ## Output contract - RED/GREEN/REFACTOR trace. - Test files changed and executed commands. - Coverage and confidence notes. ## References - `reference.md` - `docs/complexity-tiers.md`

Rigor Analyze / Rigor Audit read-only skill for deep learning research repositories. Use when the user wants to read and understand a repository, inspect model structure and training or inference entrypoints, review configs and insertion points, or flag suspicious implementation patterns without modifying code or running heavy jobs. Do not use for active command execution, broad refactoring, speculative code adaptation, or automatic bug fixing.
