Quality

Content

76%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 skill body is highly actionable with executable examples and clean structure, but workflow checkpoints and signaling of the bundled citation reference are the main gaps.

Suggestions

Add an explicit validation step in the Typical Workflow (e.g., confirm resolve-gencode-id returned a valid ID before using it, and how to handle an empty/error response).

Reference references/citation.bib from the body so the bundled citation material is discoverable and not orphaned.

Trim the redundancy between the Command Selection Guide and the Commands section, or merge them so each command's purpose and example live in one place.

DimensionReasoningScore

Conciseness

The body is largely efficient with useful boundary guidance and no padding about concepts Claude already knows; the Command Selection Guide slightly duplicates the per-command detail that follows.

4 / 5

Actionability

Every subcommand has copy-paste-ready, fully executable invocations with realistic arguments and output paths, covering all common cases.

5 / 5

Workflow Clarity

The resolve-then-query dependency and a 2-step Typical Workflow are clearly sequenced, but there are no validation checkpoints or error-recovery guidance (e.g., what to do if resolve returns nothing or the API errors).

3 / 5

Progressive Disclosure

The body is well-organized into clear sections and correctly references the real scripts/gtex_cli.py inline, but the bundled references/citation.bib is never signaled or navigated from SKILL.md.

Description

66%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 specific, distinctive, and answers both what and when, but its trigger phrasing restates the capability rather than mirroring natural user language and lacks synonym coverage.

Suggestions

Add concrete user-facing trigger phrases (e.g., 'Use when the user asks about GTEx, gene/tissue expression, or eQTLs for a variant or gene').

Broaden trigger term coverage with natural synonyms such as 'gene expression', 'tissue expression', and 'expression data'.

Expand the action list beyond two broad 'retrieve' verbs to enumerate the concrete operations (resolve GENCODE IDs, fetch median TPM, list top tissues, query regional eQTLs).

DimensionReasoningScore

Specificity

It names the domain (GTEx) and two concrete retrieve actions (quantitative RNA expression data and eQTL information) across 54 tissues, but the action list is narrow rather than comprehensive.

3 / 5

Completeness

Both a clear 'what' (retrieve RNA expression and eQTL data from GTEx across 54 tissues) and an explicit 'Use when...' 'when' clause are present, but the trigger restates the function rather than offering concrete user-facing trigger phrases.

4 / 5

Trigger Term Quality

Relevant technical keywords (GTEx, eQTL, RNA expression, tissue sites) are present, but common natural variations a user might say (e.g., 'gene expression', 'tissue expression', 'expression data') are missing.

3 / 5

Distinctiveness Conflict Risk

It carves a clear GTEx-specific niche (RNA expression + eQTL across 54 non-diseased tissues) with distinct triggers and minimal overlap risk against other skills.
