Conciseness

The body is dense with non-inferable contract details Claude could not know — the resume_prompt_id timeout recovery, the EmptyLatentImage batch_size strobing trap, Partner Node hosting requirements, ACE-Step v1 native-node specifics — with zero concept explanations or padding. Every sentence adds operational information; it matches anchor 5's 'every token earns its place'.

Actionability

Guidance is fully concrete and executable: exact env vars (COMFYUI_IMAGE_SERVER_URL, COMFYUI_MUSIC_SERVER_URL), endpoints (GET /system_stats, POST /prompt, GET /history/{prompt_id}), specific node class names (EmptyHunyuanLatentVideo, Wan22ImageToVideoLatent, SaveAudioMP3), a literal output_node example ('"108"'), folder paths, and structured payload fields (data.missing_models[]). It covers the common cases for all three tools plus failure paths.

Workflow Clarity

Explicit checkpoints exist ('Check the latent node before running any unfamiliar video workflow', check ComfyUI history before retrying from scratch) and a real error-recovery feedback loop (resume_prompt_id, missing_models install flow). However, the overall pre-flight sequence is scattered across topical sections rather than presented as an ordered workflow or consolidated checklist, which keeps it below anchor 5.

Progressive Disclosure

Well-organized ##/### sections with no nested references and no content that clearly belongs in a separate file at this length (~78 lines). It falls short of anchor 5 because there is no reference structure at all — the skill is over the 50-line simple-skill threshold and has minor placement awkwardness (Partner Nodes nested under Server Contract, Music appended after Failure Handling) — but navigation is easy and nothing is buried.

Specificity

The description lists several specific concrete items — 'custom workflow_json/workflow_path inputs, output_node selection, missing model setup, LoRAs, low-VRAM workflow choices, and community workflow imports' — but phrases them as topics rather than actions, and never states what the skill actually does with them. It is above anchor 3 (only 1-2 concrete actions) but the verb-less phrasing keeps it below anchor 5's comprehensive action coverage.

Completeness

The description is entirely a 'when' clause ('Use when working with ComfyUI workflows in OpenMontage, including...'); the 'what' is only implied by the enumerated topics, with no explicit statement of what the skill does. It is clearly above anchor 2 ('Use when working with documents' — vague in both dimensions) because the enumeration conveys concrete scope, but below anchor 4, which requires both 'what' and 'when' explicitly.

Trigger Term Quality

Strong natural terms for this domain: 'ComfyUI', 'comfyui_image/comfyui_video/comfyui_music', 'LoRAs', 'low-VRAM', 'community workflow imports'. However, common user phrasings such as 'generate an image/video/song with ComfyUI' and model family names a user would actually say (Wan, LTXV, ACE-Step) are missing, so it falls short of anchor 5's comprehensive synonym coverage.

Distinctiveness Conflict Risk

'ComfyUI workflows in OpenMontage, including comfyui_image/comfyui_video/comfyui_music' carves out a clear niche with distinct, tool-specific triggers; a user would only invoke this when working with these exact tools, so conflict risk is minimal.
