Conciseness

Lean and well-sectioned with no over-explanation of concepts Claude already knows, but the getLigandsByPDBs/1Q0L example object is repeated in both the Input section and the Execution block, a minor redundancy that could be trimmed.

Actionability

Provides a concrete executable bash command, the script path, base_url, preferred endpoint paths, and copy-paste-ready JSON input examples covering the common cases.

Workflow Clarity

A simple single-purpose skill whose single action (pipe JSON to scripts/rest_request.py) is unambiguous, with documented success/failure interpretation (ok=false, error.code/error.message) and read-only lookups that need no destructive-validation checkpoint.

Progressive Disclosure

Under 50 lines with clearly organized sections and a real one-level reference to scripts/rest_request.py; the References section explicitly states no further runtime references are needed.

Specificity

Lists multiple concrete actions ('Submit compact BindingDB REST API requests', 'ligand-target binding lookups by PDB, UniProt, or similarity search', 'save raw payloads only on request') with comprehensive coverage of the skill's entry points, in third person.

Completeness

Explicitly states what it does (submit REST requests, run lookups, save payloads) and when to use it ('Use when a user wants concise BindingDB summaries') with a concrete trigger phrase.

Trigger Term Quality

Strong natural-term coverage ('BindingDB', 'ligand-target binding', 'PDB, UniProt, similarity search', 'concise BindingDB summaries'), but a few common synonyms users might say (SMILES, compound, target, Ki/IC50) are absent.

Distinctiveness Conflict Risk

Occupies a clear niche (BindingDB ligand-target binding via PDB/UniProt/similarity) with distinct triggers and minimal overlap risk with other skills.
