What problem does it solve? Untested skill documentation often fails in practice because agents rationalize around rules under pressure. This Skill applies test-driven development to skill authoring so you verify that agents actually follow instructions before deployment. ## Core Features & Use Cases - TDD-based skill authoring: Run baseline pressure scenarios with subagents (red), write the minimal skill addressing observed failures (green), then close rationalization loopholes (refactor). - Claude Search Optimization guidance: Write discovery-focused descriptions with trigger conditions, keyword coverage, and token-efficient structure. - Testing methodology references: Includes guides for pressure-scenario testing with subagents, persuasion principles for discipline-enforcing skills, and Anthropic's official best practices. - Use Case: Before publishing a new TDD-enforcement skill, run a scenario where an agent has 200 lines of untested code and a dinner deadline, capture its rationalizations verbatim, then harden the skill until compliance holds under maximum pressure. ## Quick Start Ask the agent to help you create a new skill using the writing-skills TDD workflow, starting with a baseline pressure scenario before writing any documentation.
