Use this skill when writing new features, fixing bugs, or refactoring code. Enforces test-driven development with 80%+ coverage including unit, integration, and E2E tests.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Test-Driven Development Workflow This skill ensures all code development follows TDD principles with comprehensive test coverage. ## When to Activate - Writing new features or functionality - Fixing bugs or issues - Refactoring existing code - Adding API endpoints - Creating new components ## Core Principles ### 1. Tests BEFORE Code ALWAYS write tests first, then implement code to make tests pass. ### 2. Coverage Requirements - Minimum 80% coverage (unit + integration + E2E) - All edge cases covered - Error scenarios tested - Boundary conditions verified ### 3. Test Types #### Unit Tests - Individual functions and utilities - Component logic - Pure functions - Helpers and utilities #### Integration Tests - API endpoints - Database operations - Service interactions - External API calls #### E2E Tests (Playwright) - Critical user flows - Complete workflows - Browser automation - UI interactions ## TDD Workflow Steps ### Step 0: Detect the Test Runner Do not assume `npm test`. The commands in the steps and examples below use `<test>`, `<test-watch>`, and `<coverage>` as placeholders for the project's actual runner. Resolve them once before starting: …

How to install
mdr add affaan-m/ecc/tdd-workflow@sha256:e9507695657b05f2The line at the top of this page pins the label git:20260918.c752aac, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
