Conciseness

The body is lean and sectioned with no padding or explanation of concepts Claude already knows; every line earns its place and assumes competence.

Actionability

Provides a copy-paste-ready bash command, concrete JSON input examples, explicit required/optional fields, and specific Rhea query patterns covering the common cases.

Workflow Clarity

This is a simple single-purpose skill (run a Rhea REST request) whose single action is unambiguous: named script, base_url, endpoint, format, query-narrowing rules, and a re-run instruction; no destructive/batch validation cap applies.

Progressive Disclosure

Under 50 lines with well-organized sections and a single correctly-referenced bundle file (scripts/rest_request.py, which exists); the simple-skill exception applies, so no external reference files are needed.

Specificity

Names the Rhea domain and a concrete action ("Submit compact Rhea reaction search requests") plus the scope ("reaction IDs"), giving 1-2 concrete actions but not a comprehensive list.

Completeness

Explicitly states both what it does (submit compact Rhea search requests) and when to use it ("Use when a user wants concise Rhea summaries"), though the when-clause is somewhat narrow rather than comprehensive.

Trigger Term Quality

Relevant niche terms ("Rhea", "reaction", "reaction IDs", "biochemical reactions", "concise Rhea summaries") are present but lack common synonyms or variations a user might naturally phrase differently.

Distinctiveness Conflict Risk

Rhea is a specific biochemical-reaction database niche with distinct triggers, so it is clearly distinguishable from other skills with minimal overlap risk.
