Conciseness

The body is dense with earned tokens — channel-fit matrix, per-channel templates with hard constraints ('≤80 chars, no marketing', '5-8 tweets', '150-200 words'), and a concrete find command. A few lines could be trimmed (e.g., 'LinkedIn rewards longer posts and personal framing' restates what the template's bracketed guidance already implies), which fits anchor 4 ('efficient; minor instances that could be trimmed') better than the fully lean anchor 5.

Actionability

Guidance is highly executable: exact character limits, tweet-by-tweet thread skeleton, per-subreddit structure, a copy-paste find command, and a day-by-day timing cadence. It falls short of anchor 5 mainly because the stated output format depends on 'docs/output-kit.md' ('40-line CLI max, box-drawing skeleton, unified severity indicators, compressed prose') — a file that does not exist in the bundle, leaving the actual output format underspecified.

Workflow Clarity

Steps 0-4 form a coherent sequence (gather context → score channels → write per-channel copy → repurposing → timing) with checkpoints like 'Read sub rules before posting' and 'explain why the others are skipped'. No destructive or batch operations, so no validation cap applies, but there are no feedback loops (e.g., how to adjust if a channel underperforms beyond the single Day 7 re-engage), which keeps it at anchor 4 rather than 5.

Progressive Disclosure

The skill is a single SKILL.md with no references/, scripts/, or assets/ directories, yet the body points to 'docs/output-kit.md' and '/atlas-report' — the former is absent from the bundle, making the one external reference broken rather than clearly signaled. Structure of the inline content is decent but the dangling reference and undocumented delegation anchor it at 3 ('some structure; references present but not clearly signaled').

Specificity

Concrete deliverables are enumerated — 'channel-by-channel plan covering HN, Reddit, LinkedIn, newsletter, and Twitter/X, with timing, per-channel framing, and a repurposing plan' — naming the channels and the plan components. It sits between anchors: more specific than 'several specific actions with minor gaps' would understate it, but the verb coverage is essentially one action ('produces a plan' with attributes) rather than the multiple distinct concrete actions of the top anchor, so 4 is the best fit.

Completeness

Both halves are explicit: 'what' is 'takes a completed piece and produces a channel-by-channel plan… with timing, per-channel framing, and a repurposing plan', and 'when' is a direct 'Use when asked to…' clause with four concrete trigger phrases. This is a clean match for the top anchor; the completeness-3 cap for missing trigger guidance does not apply.

Trigger Term Quality

The quoted triggers — "distribute this post", "how do we promote this article", "write distribution copy for this piece", "where should we share this" — are natural user phrasings with good synonym coverage (post/article/piece; distribute/promote/share). This matches the top anchor's comprehensive natural-term coverage; no common variation is obviously missing.

Distinctiveness Conflict Risk

It carves a clear niche — distribution of an already-published piece across named channels — with distinct triggers that would not naturally fire a general writing or editing skill. Overlap risk with a broad 'content marketing' skill exists but is minimal, matching the top anchor better than the 'minor overlap risk' anchor below it.
