Skill Hardening

Improve a skill using the given case, but avoid overfitting. Do not directly patch for the exact case.

First:

1. Identify the general failure mode.
2. Explain why a naive fix would overfit.
3. Propose a general rule that would prevent similar failures.
4. Create 3 validation cases:
   • similar case
   • adjacent different case
   • case where the rule should not apply
5. Only then propose a minimal skill diff.

Constraints:

• Do not include names, exact file paths, exact error strings, or case-specific details unless they represent a reusable category.
• Prefer abstract decision rules over concrete commands.
• Reject any change that only improves the provided case.
• Keep examples separate from rules.
