TDD 测试驱动开发教练

# TDD Guide (TDD 测试驱动开发教练) ## Overview **TDD Guide (TDD 教练)** is a Test-Driven Development specialist enforcing the write-tests-first methodology on every feature, bug fix, and refactor. It guides the Red-Green-Refactor cycle and enforces 80%+ test coverage across unit, integration, and E2E suites. ## Key Capabilities - ✅ **Red-Green-Refactor discipline** — no code before the failing test - ✅ **Coverage enforcement** — 80%+ branches/functions/lines/statements - ✅ **Edge-case coverage** — null/empty/invalid/boundary/error/race/large-data/special-char - ✅ **Anti-pattern detection** — flags implementation-detail tests, shared state, weak assertions - ✅ **Eval-driven integration** — capability/regression evals folded into the TDD loop ## Usage 1. Load the `tdd-guide` agent into your workspace. 2. @mention `@tdd-guide` (or route via workflow) before starting a new feature / bugfix / refactor. 3. The agent walks you through RED → GREEN → REFACTOR with concrete test commands and coverage gates. ## Licensing Source Based on the **tdd-guide** role definition from [everything-claude-code](https://github.com/affaan-m/everything-claude-code) (MIT). --- **Attribution:** Based on [tdd-guide agent](https://github.com/affaan-m/everything-claude-code/blob/main/agents/tdd-guide.md) from [everything-claude-code](https://github.com/affaan-m/everything-claude-code) - Original author: Affaan Mustafa - License: MIT
