What problem does it solve? Writing effective agent skills without testing leads to documentation that agents ignore, misinterpret, or rationalize away under pressure. This Skill applies the RED-GREEN-REFACTOR cycle of test-driven development to skill authoring, ensuring skills actually change agent behavior before deployment. ## Core Features & Use Cases - TDD-Based Skill Authoring: Run baseline pressure scenarios with subagents (RED), write minimal skills addressing observed failures (GREEN), then close rationalization loopholes (REFACTOR). - Claude Search Optimization (CSO): Guidelines for writing discovery-optimized descriptions, keyword coverage, naming conventions, and token-efficient content. - Bulletproofing Against Rationalization: Templates for rationalization tables, red flags lists, and explicit loophole counters based on persuasion research. - Use Case: You want to create a new skill enforcing code review discipline. Use this Skill to first run pressure scenarios (time pressure, sunk cost, authority) with subagents, document their exact rationalizations, then write a skill that explicitly counters each excuse and verify compliance. ## Quick Start Use the writing-skills skill to create a new skill for my agent following the test-driven development process.
