Skill: Test Skills with Subagents

Overview

Every skill must be tested before deployment. The Iron Law: No skill ships without a failing test first.

Testing Protocol

Phase 1: Baseline (No Skill)

1. Run a subagent WITHOUT the skill loaded
2. Give it a scenario where the skill SHOULD be used
3. Document what the subagent does wrong
4. This establishes the "before" behavior

Phase 2: Apply Skill

1. Run subagent WITH the skill loaded
2. Same scenario as Phase 1
3. Verify the skill changes behavior correctly
4. Document improvements

Phase 3: Edge Cases

Test these rationalization patterns:

• "I already know how to do this"
• "This situation is different"
• "It would be faster to just..."
• "The user probably meant..."

Phase 4: Adversarial

Attempt to make the skill fail:

• Ambiguous inputs
• Conflicting requirements
• Time pressure scenarios
• Partial information
