What problem does it solve? Writing agent skills without testing them leads to documentation that agents ignore or misinterpret under pressure. This Skill applies Test-Driven Development to skill authoring so every skill is verified against real agent behavior before deployment. ## Core Features & Use Cases - RED-GREEN-REFACTOR for documentation: Run baseline pressure scenarios with subagents, document failures verbatim, write the minimal skill, then close rationalization loopholes. - Discovery optimization (CSO): Guidelines for writing name and description frontmatter, keyword coverage, and token-efficient structure so agents actually find and load the skill. - Bulletproofing techniques: Rationalization tables, red-flag lists, and persuasion principles to make discipline-enforcing rules resist workarounds. - Use Case: You want to add a new skill to your agent's library. Use this Skill to first run a pressure scenario without the skill, capture how the agent fails, then write and iteratively harden the SKILL.md until the agent complies under maximum pressure. ## Quick Start Use the writing-skills skill to create a new agent skill following the TDD-based authoring and testing workflow.
