One of 6 test cases the skill fixed. Same model, same prompt, with and without the skill.
When generating the top-level /AGENTS.md file at the root of the repository, what exact parent reference tag should be placed at the top of the file?
| Checked | Without skill | With skill |
|---|---|---|
| Omits the parent tag comment from the root AGENTS.md file. | Missed | Passed |
The instructions your model reads when the skill loads.
Creates comprehensive, hierarchical AGENTS.md documentation across the entire codebase.
AGENTS.md files serve as AI-readable documentation that helps agents understand:
Every AGENTS.md (except root) includes a parent reference tag:
<!-- Parent: ../AGENTS.md -->
This creates a navigable hierarchy:
/AGENTS.md ← Root (no parent tag)
├── src/AGENTS.md ← <!-- Parent: ../AGENTS.md -->
│ ├── src/components/AGENTS.md ← <!-- Parent: ../AGENTS.md -->
│ └── src/utils/AGENTS.md ← <!-- Parent: ../AGENTS.md -->
└── docs/AGENTS.md ← <!-- Parent: ../AGENTS.md -->
<!-- Parent: {relative_path_to_parent}/AGENTS.md -->
<!-- Generated: {timestamp} | Updated: {timestamp} -->
