Quality

Content

67%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 thorough, actionable skill-creation guide with real scripts and clear sequencing, but it is somewhat verbose and repeats guidance. Tightening redundant passages and de-duplicating the references rule would lift conciseness.

Suggestions

Consolidate the repeated references/>500-lines rule into a single canonical statement instead of restating it across "Bundled Resources", "Planning Checklist", "Step 4", and "Progressive Disclosure".

Trim generic exposition (e.g., the "What Skills Provide" and design-pattern primers) that restates concepts the agent already knows, to improve token efficiency.

Add an explicit validate-fix-retry feedback loop around the validate step rather than marking it optional, to strengthen workflow clarity for iterative refinement.

DimensionReasoningScore

Conciseness

The ~430-line body restates the references/>500-lines rule multiple times and explains concepts the agent likely knows (what skills are, generic design-pattern exposition), so it is mostly efficient but includes unnecessary explanation that could be tightened.

3 / 5

Actionability

Concrete executable commands (init_skill.py with flags, quick_validate.py), real bundled scripts, and copy-ready YAML/bash examples provide mostly executable guidance with only minor abstract steps like "Clarify use cases".

4 / 5

Workflow Clarity

A clear six-step creation sequence (Understand through Iterate) plus a parallel install flow is present with a validation step, though validation is marked optional and lacks an explicit fix-and-retry feedback loop.

4 / 5

Progressive Disclosure

Section structure is clear, bundled scripts exist and are referenced by path, and content is appropriately inline with no needless references; the main gap is that the single ~430-line SKILL.md brushes against its own keep-under-500-lines guidance.

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 is well-constructed: third-person voice, explicit what-and-when structure, and concrete enumerated triggers. It is comprehensive for the skill-management domain with only minor synonym gaps.

DimensionReasoningScore

Specificity

"Create, install, or update skills" lists several concrete actions across the skill-management domain, comparable to the anchor listing several specific actions with minor coverage gaps (e.g., no mention of deletion or listing).

4 / 5

Completeness

It explicitly answers both what ("Create, install, or update skills") and when (a "Use when..." clause enumerating three concrete trigger scenarios), matching the anchor that requires both with concrete trigger phrases.

5 / 5

Trigger Term Quality

Natural trigger phrases like "installing a skill from a URL or remote source", "creating a new skill from scratch", and "updating or restructuring existing skills" match what users would say, though a few synonyms are missing.

4 / 5

Distinctiveness Conflict Risk

Skill creation/installation is a clear niche with distinct triggers ("installing a skill from a URL", "creating a new skill from scratch") and minimal overlap risk with other skills.
