## Paths

Give the agent a complete skill folder:

```text
skills/engineering/tdd/
skills/engineering/diagnose/
skills/engineering/codebase-design/
skills/engineering/domain-modeling/
skills/release/release-prep/
skills/documentation/documentation-system/
skills/productivity/writing-great-skills/
```

The `SKILL.md` file is the entry point. Helper files in the same folder are part of the skill.
