Conciseness

Body is lean — prerequisites table, shapes-in-comments code, and a terse troubleshooting table with no padding — but the remote-compute paragraph inlines convoluted harness guidance ('A final .result() read reports whether its follow-up was suppressed or had already been committed; otherwise the app starts the later analysis turn for an unread final result') that duplicates the remote-compute-ssh skill it already points to. Not 5 because that passage could be trimmed; not 3 because everything else earns its place.

Actionability

Executable code exists for model loading ('Borzoi.from_pretrained(...).cuda().eval()') and job submission, but the skill's primary advertised use case — variant scoring — gets only one prose sentence ('run ref/alt windows centred on the variant and compare per-track output') with no code for building the (batch, 4, 524288) one-hot input or the ref/alt comparison, and the referenced 'borzoi_run.py' is not in the bundle. Key details are missing, matching anchor 3 rather than 4.

Workflow Clarity

The remote-compute flow has a clear sequence (compute_details → create → submitJob → retain job_id → status() → result()), but the core analysis workflow has no step sequence at all and there are no validation checkpoints anywhere (no output-shape check, no job-success check before consuming results). Sequence present with checkpoints missing/implicit matches anchor 3; not 4 because the main-use-case steps are underspecified.

Progressive Disclosure

No bundle files exist, and nothing that belongs in a separate file is inlined — every section is short and belongs in SKILL.md. The single cross-reference (the remote-compute-ssh skill) is one level deep and clearly signaled, and section headers make navigation trivial. Matches anchor 5 for a compact, self-contained skill.

Specificity

Names multiple concrete actions with named assays — 'Predict genome-wide functional tracks (RNA-seq, CAGE, DNase, ChIP) from DNA sequence', 'Scoring the regulatory effect of a variant on expression/accessibility', 'Generating predicted coverage tracks for a locus', 'Prioritising non-coding variants by predicted track delta' — comprehensive coverage with no generic filler. Not 4, since the action list has no coverage gaps.

Completeness

Explicitly answers both: what ('Predict genome-wide functional tracks... from DNA sequence with Borzoi') and when (a numbered 'Use this skill when' clause with three concrete trigger scenarios). Matches the anchor-5 example structure exactly; the 'when' is fully explicit, so not 4.

Trigger Term Quality

Good natural keyword coverage ('RNA-seq, CAGE, DNase, ChIP', 'regulatory effect', 'expression/accessibility', 'non-coding variants', 'Borzoi'), but common synonyms users would actually say are missing — notably ATAC-seq (the most common accessibility assay) and 'chromatin'. Not 5 because synonym coverage is incomplete; not 3 because the included terms are natural phrases, not just jargon.

Distinctiveness Conflict Risk

A clear niche (Borzoi DNA-to-track prediction) with model- and assay-specific triggers ('Borzoi', 'CAGE', 'predicted track delta') that no generic genomics or annotation skill would claim. Minimal conflict risk; matches anchor 5.
