Conciseness

The body is lean and assumes competence — no concept explanations, terse one-line workflow steps — but integration information is repeated across "Workflow Steps" (steps 7–9), the "MCP" section ("uses `subsonic-mcp` for playlist output; Obsidian MCP for note creation"), and the "Companion Skills" section. That duplication is a minor trim candidate, fitting anchor 4 ('efficient; minor instances that could be trimmed') rather than anchor 5's every-token-earns-its-place.

Actionability

Some concrete guidance exists — named sources and targets ("`dj-library-curator` crates", "`subsonic-mcp`", "`obsidian-music-journal`", "`homelab-logbook`") and example invocations — but the core task stays high-level: "Apply harmonic mixing rules (Camelot Wheel); build BPM flow curve respecting energy shape" without stating which Camelot transitions are compatible, what BPM-change limits to respect, what an energy value means, or the M3U output format. This is 'some concrete guidance but incomplete; missing key details' (3), not the mostly-executable anchor 4.

Workflow Clarity

Nine steps are clearly and logically ordered with a user feedback loop (step 5 "Review: Present draft tracklist..." → step 6 "Refine: Accept user edits") and destructive-operation protection in Safety ("Always confirm before overwriting an existing set plan"). Minor gap: no post-export verification, keeping it at anchor 4 rather than anchor 5's explicit validate-and-retry checkpoints.

Progressive Disclosure

The skill is under 50 lines with well-organized sections (Purpose, Invocation, Workflow Steps, Safety, MCP, References, Companion Skills) and clearly labeled one-level-deep external URL references. The references/ and scripts/ bundle directories are empty (only .gitkeep), so nothing needs splitting; per the simple-skill scoring note this earns a 5 on section organization alone.

Specificity

The description lists multiple concrete actions — "Design and sequence DJ sets using harmonic mixing principles, BPM flow analysis, and energy curve planning; generate set plans and tracklists from the curated DJ library" — covering the domain comprehensively rather than vaguely. This matches the anchor 'lists multiple specific concrete actions; comprehensive coverage' and exceeds anchor 4, whose hallmark is a noticeable coverage gap.

Completeness

The 'what' is clearly and concretely stated, but there is no "Use when..." clause or any equivalent explicit trigger guidance, capping this dimension at 3 per the judging guidelines. It is above anchor 2 (which requires a vague or missing 'what') but fails anchor 4's requirement that both what and when be present.

Trigger Term Quality

Natural phrases users would say are present — "DJ sets", "harmonic mixing", "BPM", "tracklists", "set plans" — but common synonyms and format terms like "mix", "mixtape", "playlist", and "M3U" are absent. This fits 'good keyword coverage; a few natural terms missing' (4) rather than the comprehensive synonym/extension coverage of anchor 5.

Distinctiveness Conflict Risk

The DJ set-sequencing niche with harmonic mixing, BPM flow, and energy curves is mostly distinct from generic music skills, but "generate set plans and tracklists from the curated DJ library" carries minor overlap risk with the closely related library-curation/playlist skills. It fits 'mostly distinct; minor overlap risk with closely related skills' better than anchor 5's minimal-conflict bar.
