Conciseness

The body is command-first with almost no padding for concepts Claude already knows; tables (script reference, druggability classes, method comparison) are dense and useful. Minor over-explanation exists — the Overview, Key capabilities, and When to Use sections restate the same capabilities three times — keeping it below the lean anchor. Not a 3 because the excess is minor trimming, not genuinely unnecessary explanation.

Actionability

Every workflow is a complete, copy-paste-ready command with real flags and file names, the full pipeline (Workflow 6) includes the exact JSON-parsing shell glue for handing off pocket centers to docking, and output JSON schemas are shown verbatim. This matches the fully-executable anchor covering common cases.

Workflow Clarity

Sequences are clear with explicit validation checkpoints: Quick Verification commands validate the install before running, the Species Validation section validates input before proceeding, the method-agreement rule (centers within 5 A) validates results, and Troubleshooting provides ordered fix-and-retry feedback loops ("adjust the script's parameters... Do NOT abandon the skill scripts"). Not a 4 because checkpoints are present at every stage, not just most.

Progressive Disclosure

Scored against the actual bundle: the four scripts are clearly and accurately referenced via the Script Reference table and inline commands, but references/methods_guide.md exists in the bundle and is never referenced from the body, making it undiscoverable. Additionally, the body inlines method-strengths and tuning guidance that overlaps the guide's content, which is the should-be-separate-inline pattern. Not a 4 because an entire reference file being orphaned is more than a minor organization gap.

Specificity

The description lists multiple specific concrete actions — "Grid-based, fpocket, and P2Rank detection", "druggability scoring", "visualization", "cross-structure comparison" — in third person, with comprehensive coverage of the skill's capabilities. It matches the anchor for multiple specific concrete actions with comprehensive coverage; there is no missing capability area.

Completeness

The "what" is clearly and concretely answered (detection, scoring, visualization, comparison), but there is no "Use when..." clause or equivalent explicit trigger guidance, which caps completeness at 3 per the judging guidelines. Not a 2 because the "what" half is fully explicit rather than vague.

Trigger Term Quality

Good natural keyword coverage: "binding pocket detection", "druggability assessment", plus distinctive tool names (fpocket, P2Rank). However, common user phrasings like "active site", "binding site", or "find binding pockets" are absent, so it falls just short of the comprehensive-synonyms anchor. Not a 3 because the included terms are natural phrases users would actually say, not jargon.

Distinctiveness Conflict Risk

It carves out a clear niche (pocket detection/druggability) with distinct triggers including the unique method names fpocket and P2Rank, minimizing conflict risk with adjacent skills like docking or binding-affinity prediction. It does not fit the minor-overlap anchor for 4 because the method names and druggability framing are uniquely attributable to this skill.
