Conciseness

Mostly efficient and action-oriented, but the cat/jq parsing warning is repeated in both 'Core Rules' and the 'Parsing Output (CRITICAL)' section, and the 'Type A' biosample explanation could be trimmed slightly.

Actionability

Provides copy-paste-ready, fully executable `uv run scripts/...` commands with real flags and concrete accessions across search, details, biosamples, gwas, entex, and more, covering the common cases comprehensively.

Workflow Clarity

Clear, consistent sequence (run wrapper → save to /tmp → parse with jq) and sequenced prerequisites, with built-in resilience noted (rate limiting, mm10 fallback), but no explicit validation/error-recovery checkpoint for failed or empty queries.

Progressive Disclosure

Keeps the body as an overview with bulk reference material (JSON output structure, GraphQL schema) split into well-signaled, one-level-deep files in references/ that genuinely exist.

Specificity

Names concrete actions tied to specific APIs — 'Query the ENCODE Registry of cis-Regulatory Elements (cCREs) via the SCREEN GraphQL API' and 'make custom queries to the ENCODE Portal REST API for experiments and files (ChIP-seq peaks, etc.)' — but the trailing 'etc.' and broad 'files' leave minor coverage gaps versus a fully enumerated list.

Completeness

Explicitly answers both what (query cCREs via SCREEN GraphQL, custom REST queries for experiments/files) and when ('Use when you want to query regulatory annotations or raw experimental data across human cell types') with concrete trigger phrasing.

Trigger Term Quality

Includes natural domain terms a genomics user would say — 'regulatory annotations', 'raw experimental data', 'ChIP-seq peaks', 'human cell types', 'ENCODE', 'cCREs' — with good coverage, though a few synonyms (e.g. 'enhancers', 'promoters') are absent.

Distinctiveness Conflict Risk

Occupies a clear niche (ENCODE cCREs, SCREEN GraphQL, ENCODE Portal REST) with distinct, domain-specific triggers and minimal overlap risk with other skills.
