Conciseness

Mostly efficient with real domain specifics (tool names, QC thresholds, organ codes), but the intro paragraph restates the description and the ASCII 'Workflow Overview' overlaps heavily with the 'Phase Summaries' section, so it could be tightened.

Actionability

Provides concrete executable guidance — parameterized tool calls like HuBMAP_search_samples(organ="LK", sample_category="block", registered_only=True, limit=5), explicit QC numbers, and runnable scanpy code blocks — with minor gaps where some phases are described only at a high level inline.

Workflow Clarity

The Phase 1-8 sequence with an ASCII flow diagram and embedded thresholds (min 200 genes, 500 UMI, <20% MT, FDR<0.05) is clearly ordered with most checkpoints present, but explicit validate->fix->retry feedback loops are not spelled out.

Progressive Disclosure

Sections are well-organized and reference links are clearly signaled one level deep, but the referenced files (code_examples.md, report_template.md) do not exist in any bundle directory, and large chunks that could be separate files (the HuBMAP tool catalog, the Reasoning Framework) are inlined.

Specificity

Lists multiple concrete actions ('Maps gene expression to tissue architecture, identifies spatially variable genes (SVGs), tissue-domain segmentation, and cell-cell interaction inference') plus four named platforms, giving comprehensive coverage rather than just 1-2 actions.

Completeness

Explicitly answers both what ('Maps gene expression... identifies SVGs... segmentation... cell-cell interaction inference') and when ('Use for spatial gene-expression questions, tissue architecture analysis, and SVG identification') with concrete trigger phrases.

Trigger Term Quality

Covers natural user terms including platform names (Visium, MERFISH, seqFISH, Slide-seq), 'spatial gene-expression', 'tissue architecture', and 'SVG' synonyms; a user would naturally say these when asking for this skill.

Distinctiveness Conflict Risk

Occupies a clear spatial-transcriptomics niche with platform-specific triggers, distinct from general single-cell or gene-enrichment skills; minimal conflict risk.
