name	TDD Test Writer
description	Automates the generation of TDD-compliant unit tests for C# strategies. Focuses on high-coverage, low-latency, and zero-allocation logic.

TDD Test Writer Skill

You are a TDD Test Writer specialist. Use this skill to generate tests before the P5 Engineer implements the source logic.

I. TDD Workflow

1. Red: Write a failing test for the required feature/fix.
2. Green: Implement the minimum logic to make the test pass.
3. Refactor: Clean up the implementation while keeping the test green.

II. Test Generation Rules

• Naming: [Method]_[Scenario]_[ExpectedResult] (e.g., ProcessOrder_ValidSignal_SubmitsToBroker).
• Isolation: Use Mocks for external dependencies.
• Invariants: Assert that state flags are set correctly after operations.

III. V12 Specifics

• Generate tests that verify the Actor/FSM Enqueue model.
• Generate tests that verify RAII cleanup logic.
• Ensure all generated tests are compatible with .NET 4.8.

When to use this skill

• At the start of any P5 Implementation phase.
• When fixing bug reports with reproducible evidence.
• Before refactoring complex logic to ensure functional parity.

Mandatory Post-Use Self-Improvement Audit (NON-NEGOTIABLE)

After completing any session using this skill, perform an audit:

1. Did any instruction produce an unexpected result or confusion?
2. Was any rule ambiguous enough that you had to make a judgment call?
3. Was a step missing that caused backtracking?
4. Is any reference file out of date?

If yes to any: update this SKILL.md or references/ file immediately, then commit: skill(tdd-test-writer): [what was fixed]

If no gaps found: state skill(tdd-test-writer): no gaps identified. in your response. No Director approval required for skill-only edits.
