Quality

Content

63%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, well-sequenced guide with concrete commands and a validation loop, but it is verbose for a meta-skill and references bundled files (references/*.md, scripts/*.py) that are not present in the package, undermining its progressive-disclosure structure.

Suggestions

Either include the referenced bundle files (references/workflows.md, references/output-patterns.md, scripts/init_skill.py, scripts/package_skill.py) or remove the references that point to them, so signaled navigation resolves to real files.

Trim padding that an able model already knows — e.g. the "About Skills" section, the "What Skills Provide" list, and the bridge/path metaphor — to reduce the near-500-line body toward the lean target the skill itself advocates.

Tighten Step 6 (Iterate) from a generic list into a concrete, checkpointed feedback loop (e.g. identify failure -> update SKILL.md or resource -> re-run packaging validation -> confirm).

DimensionReasoningScore

Conciseness

The ~460-line body is mostly useful procedural guidance but includes padding such as the "About Skills" overview, the "What Skills Provide" list, and the bridge/path metaphor that explain concepts an able model already grasps; it could be tightened without losing clarity.

3 / 5

Actionability

Provides concrete executable commands ("scripts/init_skill.py <skill-name> --path <output-directory>", "scripts/package_skill.py <path/to/skill-folder>") and per-domain resource examples, though the SKILL.md-body authoring guidance stays somewhat abstract ("Write instructions for using the skill").

4 / 5

Workflow Clarity

A clear six-step creation process is enumerated and elaborated, with a validation feedback loop in the packaging step ("If validation fails... Fix any validation errors and run the packaging command again") and a script-testing checkpoint; the iteration step is comparatively vague, leaving a minor gap.

4 / 5

Progressive Disclosure

Sections are well-organized and references are clearly signaled ("See references/workflows.md", "See references/output-patterns.md"), but those referenced files and the scripts/ directory do not actually exist in the bundle, so navigation points to missing material and the body itself is a near-500-line monolith rather than split content.

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 third-person, clearly states both what the skill does and when to use it, and targets a distinct niche. It is strong throughout, with only minor gaps in action specificity and trigger synonym coverage.

DimensionReasoningScore

Specificity

Names the skill-creation domain and several concrete actions ("create a new skill", "update an existing skill", "extends Codex's capabilities with specialized knowledge, workflows, or tool integrations"), but the actions are somewhat abstract rather than a list of specific concrete operations, keeping it just below comprehensive.

4 / 5

Completeness

Explicitly answers both what ("Guide for creating effective skills" that extend Codex's capabilities) and when ("This skill should be used when users want to create a new skill (or update an existing skill)") with a concrete trigger clause.

5 / 5

Trigger Term Quality

Includes a natural trigger phrase users would say ("users want to create a new skill (or update an existing skill)") with good coverage, though a few natural synonyms (e.g. "build a skill", "make a skill") are missing.

4 / 5

Distinctiveness Conflict Risk

Occupies a clear, narrow niche (meta-skill for authoring other skills) with distinct triggers unlikely to fire for unrelated skills.
