Quality

Content

92%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

An exemplary short one-shot display skill: exact copy-paste output, precise rendering rules, and a well-drawn honesty boundary preventing fabricated per-repo numbers. The only blemish is a small duplication between the intro and the Boundaries section.

DimensionReasoningScore

Conciseness

Nearly lean — every line is data, a rendering rule, or a constraint, with no explanation of concepts Claude already knows. Minor redundancy: the one-shot prohibition stated in the intro ("do NOT change mode, write flag files, or persist anything") is restated under Boundaries ("One-shot display. Edits nothing, changes no mode."). The date/version mentions (2026-10-07, Opus 5.5) are benchmark provenance, not conditional date-based instructions, so they do not trigger the time-sensitivity penalty.

4 / 5

Actionability

The scoreboard ASCII block with exact figures is copy-paste ready, and the rendering rules are concrete ("bar length shows ponytail as a share of the no-skill baseline; the label carries the exact figure"). Guidance is fully executable for this instruction-only skill.

5 / 5

Workflow Clarity

A simple, single-purpose skill under 50 lines whose single action ("Display this scoreboard when invoked") is unambiguous, reinforced by an explicit honesty guardrail. No destructive or batch operations, so the validation cap does not apply — the simple-skill exception yields 5.

5 / 5

Progressive Disclosure

The body is well under 50 lines with no need for external references, and content is organized into clear sections (Scoreboard, Honesty boundary, Boundaries). The `benchmarks/results/2026-10-07-agentic.md` mention is a data-source citation, not a reference file, so structure scores 5 under the no-bundle guideline.

Description

87%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong description: concise, third-person, with an explicit what-and-when pair and concrete natural-language triggers. The only improvement space is mentioning the scoreboard rendering form and a few more trigger synonyms.

DimensionReasoningScore

Specificity

Names the concrete deliverable ("Show ponytail's measured savings (code, cost, speed) from the benchmark") with source and one-shot qualifiers. Minor gap — the rendering form (a scoreboard/ASCII bars) is not stated, so it does not reach comprehensive anchor 5, but it exceeds the 1-2-concrete-actions level of anchor 3.

4 / 5

Completeness

Explicitly answers both: what ("Show ponytail's measured savings (code, cost, speed) from the benchmark") and when ("Use for /ponytail-gain, 'what does ponytail save', 'ponytail impact'") with concrete trigger phrases — a direct match to the anchor-5 pattern.

5 / 5

Trigger Term Quality

Natural trigger phrases a user would say ("what does ponytail save", "ponytail impact", /ponytail-gain). Good coverage, but common variations like "ponytail savings", "how much does ponytail save", or "benchmark results" are missing, keeping it below comprehensive anchor 5.

4 / 5

Distinctiveness Conflict Risk

"ponytail" is a unique niche term and all triggers are specific to it, so the skill is clearly distinguishable with minimal conflict risk against any other skill.
