Enhance Skill by Derailment

Improve a skill by making a subagent use it on a real task, reading the execution trace for friction, and fixing the skill text where it broke.

When to use

Use this skill if you are:

• testing whether a SKILL.md actually holds up when an agent uses it ("test my skill", "is this skill any good", "does this skill work")
• hardening an existing skill before publishing it or relying on it
• diagnosing why an agent keeps drifting, guessing, or stalling on a skill that "should" work
• running a derailment / friction-trace pass on a draft skill
• post-edit verifying that a fix to a skill actually closed the friction it was meant to close
• deciding which lines, examples, or routing cues in a skill are load-bearing vs dead weight

Do NOT use this skill if you are:
