Writing Skills
Overview
Writing skills IS Test-Driven Development applied to process documentation. Write pressure tests, watch agents fail, write the skill, watch them pass, close loopholes.
Core principle: If you did not watch an agent fail without the skill, you do not know if the skill teaches the right thing.
TDD for Skills
| TDD Concept | Skill Creation |
|---|---|
| Test case | Pressure scenario with subagent |
| Production code | Skill document (SKILL.md) |
| RED | Agent violates rule without skill |
| GREEN | Agent complies with skill present |
| REFACTOR | Close loopholes |

nameanddescriptiononly - Description: "Use when..." (triggering conditions only, never summarize workflow)
- Flat namespace, separate files only for heavy reference or reusable tools
Tool Use
