Conciseness

The body is dense with skill-specific operational knowledge (officecli commands, property tables, curl recipes) and avoids explaining concepts Claude already knows, but at ~550 lines several sections could be tightened — the Step 6 website catalog with filter walkthroughs and the scripted user-dialogue templates in the Model Discovery Flow pad the file. Not a 4 because the trimming opportunities are more than minor.

Actionability

Guidance is fully executable throughout: copy-paste-ready `officecli add ... --type 3dmodel` commands with exact props, working Sketchfab/Khronos curl commands, a runnable Python build loop, and concrete numeric ranges (area ratio >= 1.5x, roty deltas 30-90°). The common cases are covered with specific, complete commands.

Workflow Clarity

The multi-step flows are clearly sequenced with explicit validation checkpoints and feedback loops: a compatibility gate before generation, post-download verification (file exists, .glb, <50MB), per-slide coordinate verification via `officecli get --depth 1`, and a Phase 4 checklist (one model3d per slide, same name prop, area-ratio rule, no repeated patterns). Error recovery paths are given for install failures and Sketchfab login walls.

Progressive Disclosure

The body is well-sectioned with headers, but it is a single monolithic ~550-line file with no bundle files (no references/, scripts/, assets/); the design-system material (10 color palettes, 8 font pairings, layout patterns, camera language) is inline where it clearly belongs in a separate reference file. It is above 2 because section structure and navigation within the file are good, and the one external pointer (`../morph-ppt/reference/styles/INDEX.md`) is clearly signaled.

Specificity

The description lists several concrete actions — "GLB model insertion, cinematographic camera, model-content layout, and enriched visual design system" — which go beyond naming the domain. It is not a 5 because "cinematographic camera" and "enriched visual design system" are somewhat abstract and the actions are not as fully itemized/comprehensive as the anchor-5 example.

Completeness

The "what" is clear (extends morph-ppt with GLB insertion, camera work, layout, and design system), but there is no "Use when..." clause or equivalent explicit trigger guidance, which caps completeness at 3 per the judging guidelines. It is above 2 because the what-side is specific, not vague.

Trigger Term Quality

Relevant keywords like "3D", "Morph", "PPT", and "GLB" are present, but the most natural user phrasings — "PowerPoint", ".pptx", "presentation", "3D model" — are missing. Not a 4 because the omission of "PowerPoint/.pptx" is the single most likely variation a user would actually say.

Distinctiveness Conflict Risk

The 3D/GLB niche is somewhat specific, but "3D Morph PPT" shares its core trigger terms with the parent `morph-ppt` skill, so a plain "morph ppt" request could match either skill. Not a 4 because the overlap risk is with its own named parent rather than a merely "closely related" skill.
