Scenario by scenario
| Scenario | Winner | Why |
|---|---|---|
| Agent must auto-select between many methodology skills | either | Trigger clarity decides — clearer triggers reduce routing errors. |
| Output must be a specific file format or structured data | one-three-one-rule | Output specificity determines whether downstream tools can rely on the result. |
| Skill must be readable and complete out of the box | one-three-one-rule | Self-containment matters when you're not the original author. |
| Cross-team or cross-project reuse expected | one-three-one-rule | Reusability separates one-off scripts from durable building blocks. |
