Conciseness

Nearly every line is adapter-specific knowledge Claude cannot know (pricing math, the `store` gotcha, SynthID watermark, tag indexing, unsupported controls), with no padding about concepts Claude already knows. It is not level 5 because sections like the fal.ai/Runway/ComfyUI route table and some editorial framing could be trimmed or offloaded.

Actionability

Guidance is copy-paste ready: the official generation prompt example, the timecode snippet "[0-3s] A person is walking [3-6s] They stop and turn around", image-ref binding examples, and concrete edit deltas like "Make the phone invisible. Keep everything else the same.", plus exact parameter names (`previous_interaction_id`, `operation="edit_video"`, `reference_image_paths`, `resume_download`). Specific examples cover the common generation, editing, timecode, text, and reference-image cases, matching the top anchor.

Workflow Clarity

The conversational-editing workflow is a clear numbered 4-step sequence (generate → return `previous_interaction_id` with only the delta → pin with "Keep everything else the same" → refine in layers), with an explicit error-recovery loop for failed downloads ("Pass that payload back to `gemini_omni_video` to retry only the existing file's GET/poll flow; it must not submit another paid generation") and the `store` precondition. It is not level 5 because there is no explicit verify-the-edit-before-iterating checkpoint; it is above level 3 because recovery and precondition checkpoints are spelled out.

Progressive Disclosure

The body (~120 lines, no bundle files) has well-organized, clearly headed sections covering selection, billing, prompting, editing, and limitations, with no nested references. It is not level 5 because the simple-skill exception applies only under 50 lines and some content (alternate provider routes, limitation details) could live in reference files; it is above level 3 because everything present is appropriately placed and easy to navigate.

Specificity

The description lists multiple concrete actions — "Generate and conversationally edit short videos", "generating 3-10s 720p clips with synthesized audio, rendered on-screen text, or timecoded beats", "binding reference images to roles with <FIRST_FRAME>/<IMAGE_REF_N> prompt tags", "editing an existing uploaded video" — comprehensively covering the adapter's operations. This matches the anchor for multiple specific concrete actions with comprehensive coverage; it is not level 4 because the enumerated (1)-(4) list leaves no notable gaps in capability coverage.

Completeness

It explicitly answers both questions: the "what" in "Generate and conversationally edit short videos with stable Google Gemini Omni Flash" and the "when" via an explicit "Use when: (1)...(4)" list with concrete trigger phrases. This clearly matches the top anchor; the 'when' clause is explicit and itemized, not merely present.

Trigger Term Quality

Natural user phrasings are well covered: "short videos", "clip", "edit", "generate", plus an embedded literal user request ("make the phone invisible, keep everything else the same") and the model name. It is not level 4 because the synonyms a user would naturally say for this domain (video, clip, edit, regenerate, reference image) are all present rather than only a few.

Distinctiveness Conflict Risk

The conversational-edit differentiator ("iterating on a clip with natural-language edits instead of regenerating") and the specific model name give it a mostly distinct niche, but the generic generation trigger ("generating 3-10s 720p clips") overlaps other video-generation skills like veo or seedance. It fits 'mostly distinct; minor overlap risk with closely related skills' rather than the minimal-conflict top anchor.
