A well-structured, highly actionable writing-guidelines skill: concrete do/don't rules reinforced by contrasting good/bad examples per platform, with a clearly signaled link to the writing-voice skill. Its only slack is slight redundancy in the volume of examples and post-example commentary, and a large examples section kept inline.

Dimension	Reasoning	Score
Conciseness	The body is efficient — terse rule lists and no explanations of concepts Claude already knows — but six full good/bad example blocks plus trailing commentary lines ("The difference: the good tweet teaches something specific...") could be trimmed, matching 'efficient with minor instances of over-explanation' rather than the every-token-earns-its-place of level 5.	4 / 5
Actionability	Guidance is fully concrete for an instruction-only skill: explicit per-platform limits ("LinkedIn: 3-5 lines max"), itemized remove/add lists, and copy-ready good/bad exemplars for each platform and post type covering the common cases.	5 / 5
Workflow Clarity	This is a simple single-purpose skill (draft a post) with unambiguous organization — platform rules, then what to remove, what to add, then exemplars — and no destructive or batch operations, so the simple-skill exception applies and the single action is clear end to end.	5 / 5
Progressive Disclosure	Sections are clearly headed and the one external dependency ([writing-voice](../writing-voice/SKILL.md)) is a clearly-signaled one-level reference; the ~100-line examples section could arguably be split into a separate file, which is a minor organization gap rather than misplaced content.	4 / 5

Description

82%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, well-formed description: third-person, concise, with explicit what and when clauses and natural trigger terms. Its only weakness is that the stated capability is a single action (drafting posts), leaving coverage of adjacent tasks like threads or edits implicit.

Suggestions

Broaden the action verbs beyond 'Draft' to cover adjacent capabilities (e.g., 'Draft, edit, and adapt social posts') to lift specificity.

Add one or two more natural trigger phrases such as 'social media', 'thread', or 'cross-post' to widen keyword coverage.

Dimension	Reasoning	Score
Specificity	"Draft social posts for LinkedIn, Reddit, or Twitter/X" names the domain and one concrete action across three platforms, but offers no additional actions (e.g., threads, replies, rewrites), matching the anchor for 1-2 concrete actions rather than the several-action coverage of level 4.	3 / 5
Completeness	It explicitly answers both what ("Draft social posts for LinkedIn, Reddit, or Twitter/X") and when with concrete trigger phrases ("Use when asked to write a post, tweet, announcement, or platform-specific version"), matching the anchor for clear and explicit what-and-when; voice is third person so no penalty applies.	5 / 5
Trigger Term Quality	"post, tweet, announcement, platform-specific version" plus "LinkedIn, Reddit, Twitter/X" give good natural keyword coverage, but common variations like "social media", "thread", or "share" are missing, so it sits between relevant-keywords (3) and comprehensive-synonym coverage (5).	4 / 5
Distinctiveness Conflict Risk	The platform-specific social-post niche with named platforms and post/tweet/announcement triggers is clearly distinct from general writing or document skills, presenting minimal conflict risk.	5 / 5
