Conciseness

Lean and mostly efficient, but the one-shot constraint is restated in the intro, the 'Honesty boundary', and the 'Boundaries' section, which is mild repetition that could be tightened.

Actionability

Provides a concrete copy-paste ASCII template with exact measured figures and labels, but the bar-rendering guidance ('bar length shows the measured range') leaves minor interpretation for Claude to fill in.

Workflow Clarity

Single-action display skill with unambiguous behavior; explicitly marks one-shot semantics and a revert path ('stop ponytail'). No destructive or batch operation is involved, so no validation checkpoint is required.

Progressive Disclosure

Under 50 lines with no need for external references, and content is organized into well-labeled sections (Scoreboard, Honesty boundary, Boundaries), meeting the simple-skill exception for a top score.

Specificity

Names the concrete action ('Show ponytail's measured impact as a compact scoreboard') with specifics (less code, cost, speed from benchmark medians), but describes a single display action rather than multiple distinct capabilities, sitting between anchors 3 and 5.

Completeness

Explicitly answers both what (display a measured-impact scoreboard) and when (a 'Trigger:' clause with concrete phrases), matching the anchor 5 example structure.

Trigger Term Quality

Comprehensive coverage of natural trigger phrases ('ponytail gain', 'what does ponytail save', 'show ponytail impact', 'ponytail scoreboard') that a user would naturally say.

Distinctiveness Conflict Risk

Has a clear niche (benchmark medians display) with distinct triggers, but sibling ponytail skills referenced in the body (ponytail-debt, ponytail-audit) create minor overlap risk on the 'ponytail' keyword.
