Conciseness

The card is lean — dense tables for levels and skills, terse command references, no concept explanations Claude already knows. The one padded spot is the Update section's fallback: "If /plugin is not recognized, your Claude Code is out of date. Update it (`npm install -g @anthropic-ai/claude-code@latest`, or `brew upgrade claude-code`) and restart" explains general Claude Code update knowledge that could be trimmed or pointed at. That minor over-explanation fits anchor 4 ('Efficient; minor instances of over-explanation') rather than anchor 5.

Actionability

Every section gives concrete, executable guidance: exact slash commands (`/ponytail band on`, `/ponytail off`), an env var (`export PONYTAIL_DEFAULT_MODE=ultra`), a config file with exact paths and a JSON snippet (`~/.config/ponytail/config.json`, Windows `%APPDATA%` variant), update commands (`/plugin marketplace update ponytail`), and per-skill trigger tables. For an instruction-only skill this is copy-paste ready — the top anchor.

Workflow Clarity

This is a simple single-purpose skill and the single action is unambiguous: "Display this reference card when invoked. One-shot, do NOT change mode, write flag files, or persist anything." Sections are clearly organized (Levels, Skills, Deactivate, Band, Configure, Update), the default level and its resolution order ("env var > config file > full") are explicit, and there are no destructive or batch operations that would require validation checkpoints, so the simple-skill exception applies.

Progressive Disclosure

The body is a compact (~68-line) reference card that needs no external bundle files — everything present genuinely belongs inline on a cheat sheet — and it is well organized with clear section headers and tables. The single external pointer ("Full docs + examples: https://github.com/DietrichGebert/ponytail") is clearly signaled and one level deep. No nested or buried references.

Specificity

"Quick reference for ponytail levels, skills and commands. One-shot display." names the domain and one concrete behavior (a one-shot reference card) but does not list any of the specific capabilities or commands it covers. This matches the anchor 'Names domain and 1-2 concrete actions, but not comprehensive' — below 4 because no several specific actions are enumerated, above 2 because the language is concrete, not generic.

Completeness

The description answers both questions explicitly: what ("Quick reference for ponytail levels, skills and commands. One-shot display.") and when ("Use for /ponytail-help, \"ponytail help\", \"how do I use ponytail\".") with concrete trigger phrases, matching the top anchor. The explicit 'Use for' clause means the missing-trigger cap of 3 does not apply.

Trigger Term Quality

"Use for /ponytail-help, \"ponytail help\", \"how do I use ponytail\"" includes the exact slash command, a spoken phrase, and a natural question, plus the keywords "levels, skills and commands" in the first sentence. Good keyword coverage with a few natural variations missing (e.g. "what does ponytail do", "ponytail modes"), which fits anchor 4 rather than the comprehensive synonym coverage of anchor 5.

Distinctiveness Conflict Risk

All triggers ("ponytail help", "how do I use ponytail", "/ponytail-help") are clearly help-oriented and unambiguous in intent. However, the description shares the "ponytail" namespace with five sibling skills (ponytail, ponytail-review, ponytail-audit, ponytail-debt, ponytail-gain), creating minor overlap risk with closely related skills — anchor 4 rather than the clear isolated niche of anchor 5.
