Quality

Content

71%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.

A thorough, mostly actionable skill-creator guide with clear sequencing and concrete templates. Its main weakness is practicing what it preaches: it teaches progressive disclosure but ships as a monolithic single file with no reference bundle.

Suggestions

Split the full frontmatter field reference and the five design patterns into references/ files (e.g. FRONTMATTER.md, PATTERNS.md) and link to them from SKILL.md to model the progressive disclosure the skill teaches.

Add an explicit validate→fix→re-validate feedback loop to the Creation Workflow so step 11 reads like a checkpoint with recovery, not just a list.

Flesh out the five design patterns and execution patterns A/B/C with one concrete code or config example each, since they are currently abstract one-liners.

DimensionReasoningScore

Conciseness

Dense, information-rich reference material with minimal padding of concepts Claude already knows; a few sections (description design reiterated after the frontmatter reference) could be tightened, keeping it just below anchor 5.

4 / 5

Actionability

Provides copy-paste-ready YAML frontmatter template, an executable bash validation script, a file-structure tree, argument-substitution and dynamic-context examples, and a 12-step workflow; the five design patterns and execution patterns remain abstract one-liners, leaving minor gaps versus anchor 5.

4 / 5

Workflow Clarity

The 12-step Creation Workflow is clearly sequenced with explicit validation/testing checkpoints (steps 10–11) and a validate→fail→exit script pattern, but lacks explicit re-loop-on-failure guidance that anchor 5 expects.

4 / 5

Progressive Disclosure

No bundle files exist (references/, scripts/, assets/ absent) despite the skill advocating a 3-layer split; substantial reference-style content (full frontmatter field reference, five design patterns, anti-patterns table) is inlined in a ~250-line single file rather than split out.

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 well-constructed description that clearly states purpose, trigger phrases, and exclusions in third person. It is comprehensive and low-conflict; the only minor weakness is that the action list is somewhat high-level rather than maximally specific.

DimensionReasoningScore

Specificity

Names the domain and several concrete actions — 「設計・作成・バリデーション・レビュー」 plus 「新規スキル作成、既存スキルの改善、description品質チェック、トリガーテスト設計」 — giving broad but slightly high-level coverage rather than the maximally granular list anchor 5 requires.

4 / 5

Completeness

Explicitly answers both what (skill design/creation/validation/review) and when (concrete launch triggers 「…で起動」) plus a negative trigger, matching the anchor-5 example structure.

5 / 5

Trigger Term Quality

Includes natural user phrases 「スキル作って」「スキル設計」「SKILL.md作成」「スキルレビュー」, which are realistic utterances; good coverage but missing common synonyms/variants that would push it to anchor 5.

4 / 5

Distinctiveness Conflict Risk

Clear niche (Claude Code SKILL.md authoring) with distinct triggers and a Do NOT use for clause scoping out スキルの実行・呼び出し, minimizing overlap with execution skills.
