Codebase Scan

Audit the codebase against another skill's criteria using a parallel agent team.

Workflow

1. Parse args & load skill

Extract the skill name from the args passed to this skill.

• If no skill name provided, list available skills in .claude/skills/ and ask the user which to scan against.
• If skill doesn't exist, list available skills and tell the user.
• Read .claude/skills/<name>/SKILL.md plus any files in references/ and rules/ subdirectories.
• Distill the skill's content into a numbered criteria checklist: a flat list of concrete, testable rules labeled C1, C2, C3, etc. Each criterion should be a single sentence describing what to check for.
• If the skill has no evaluable code criteria (e.g., workflow-only skills like why that don't define code patterns or rules), tell the user it's not scannable and stop.

2. Discover relevant files

Use the skill's criteria to infer file scope:
