Quality

Content

87%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 concise, highly actionable body that routes the agent to real helper scripts with concrete flags and examples, and is well-structured with verified one-level-deep references. The main weakness is workflow_clarity: batch install operations lack explicit validation/retry checkpoints, which the rubric caps at 3.

Suggestions

Add an explicit validation checkpoint after install (e.g. verify the skill directory now exists and contains a SKILL.md, and report failures with a retry path) to lift workflow_clarity past the destructive/batch cap of 3.

Document the error-recovery flow when a download fails with auth errors before falling back to git sparse checkout (current state vs. next action) so the install loop has a clear feedback step.

For multi-skill installs, note a per-skill success/failure summary so batch operations surface partial failures explicitly.

Dimension	Reasoning	Score
Conciseness	Lean body that assumes Claude's competence with no padding or concept over-explanation; each section (Communication, Scripts, Behavior and Options, Notes) earns its place and delivers only skill-specific facts.	5 / 5
Actionability	Provides concrete, copy-paste-ready script invocations with real flags and examples (e.g. 'scripts/install-skill-from-github.py --repo <owner>/<repo> --path <path/to/skill>', '--format json', experimental examples) covering the common cases.	5 / 5
Workflow Clarity	Decision routing (list vs install-by-name vs install-by-url) and behavior guards are present, but installation is a batch/destructive-class operation with no explicit validate→fix→retry feedback loop; the rubric caps such skills at 3 when validation checkpoints are absent.	3 / 5
Progressive Disclosure	Well-organized sections with all referenced script paths existing one level deep in scripts/ (list-skills.py, install-skill-from-github.py); a short single-purpose skill with no nested references, so structure fully satisfies navigation needs.	5 / 5

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, third-person description that states concrete capabilities and provides an explicit 'Use when' trigger covering listing and both curated and repo-based installation. Minor specificity gaps (no update/uninstall) keep it just short of perfect on coverage.

Dimension	Reasoning	Score
Specificity	Names the domain and several concrete actions — 'Install Codex skills', 'from a curated list or a GitHub repo path', 'list installable skills' — with only minor coverage gaps (no mention of update/uninstall); not a 5 because it is not fully comprehensive.	4 / 5
Completeness	Explicitly answers 'what' ('Install Codex skills into $CODEX_HOME/skills from a curated list or a GitHub repo path') and 'when' via a concrete 'Use when a user asks to list installable skills, install a curated skill, or install a skill from another repo' clause with concrete triggers.	5 / 5
Trigger Term Quality	Includes natural phrases users would say ('list installable skills', 'install a curated skill', 'install a skill from another repo'); good coverage but a few natural synonyms are missing, so above the midpoint but not comprehensive.	4 / 5
Distinctiveness Conflict Risk	Clear niche (Codex skill installer) with distinct triggers and minimal overlap risk with other skills; the GitHub-repo/curated-list framing is specific and unlikely to fire for unrelated skills.	5 / 5
