Quality

Content

77%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.

The body is a well-organized, actionable guide with a clear validated workflow and exemplary progressive disclosure. Its main weakness is conciseness: several conceptual explanations and metaphors pad the otherwise lean procedural guidance.

Suggestions

Trim over-explanatory prose such as the 'narrow bridge / open field' metaphor and the 'Skills are modular... onboarding guides' paragraph, which restate concepts Claude already grasps.

Consider condensing the 'What Skills Provide' and 'About Skills' sections into a few bullets, since the anatomy section already conveys the same information more concretely.

Tighten the 'Set Appropriate Degrees of Freedom' section to its actionable rule rather than the extended explanatory analogy.

DimensionReasoningScore

Conciseness

Mostly efficient procedural content, but includes over-explanation Claude does not need, such as the bridge/field metaphor and the 'What Skills Provide' / 'Skills are modular... onboarding guides' framing.

3 / 5

Actionability

Provides concrete, runnable commands for init and packaging and concrete resource examples, though several sections (degrees-of-freedom framework, progressive-disclosure patterns) are illustrative rather than executable.

4 / 5

Workflow Clarity

A clear six-step sequence with skip-conditions, explicit automatic validation on packaging, and a fix-and-rerun feedback loop for validation failures.

5 / 5

Progressive Disclosure

Body is well-structured with an overview and clearly signaled, one-level-deep references to real bundle files (references/workflows.md, references/output-patterns.md) plus three real scripts, matching the patterns it teaches.

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.

The description effectively answers both 'what' and 'when' with concrete, distinct triggers tied to skill creation. It is specific and unlikely to conflict with other skills, though trigger-term coverage could include a few more natural synonyms.

DimensionReasoningScore

Specificity

Names the skill-authoring domain and several concrete actions (create/update skills that add specialized knowledge, workflows, tool integrations), but stays fairly high-level rather than enumerating sub-actions like init or packaging.

4 / 5

Completeness

Clearly states what the skill does ('Guide for creating effective skills') and gives an explicit 'when' trigger clause ('This skill should be used when users want to create a new skill (or update an existing skill)...').

5 / 5

Trigger Term Quality

Includes natural phrases users would say ('create a new skill', 'update an existing skill') plus relevant vocabulary, but misses synonyms like 'build a skill' and file extensions like '.skill' or 'SKILL.md'.

4 / 5

Distinctiveness Conflict Risk

Occupies a clear, narrow niche (authoring Claude skills) with triggers specific to skill creation, so overlap with domain skills is minimal.
