Conciseness

The 29-line body contains no concept explanations, no filler, and no padding: every line is either a workflow step, a checkable product-specific constraint ("2-3 sentences max (fits ~280 chars)", "No em dashes anywhere in the post"), or a pointer to the reference. The one near-duplicate (the video rationale in the intro vs. the video constraint) serves distinct purposes (why vs. hard rule), so anchor 5 ("Lean and efficient; every token earns its place") fits better than 4.

Actionability

The guidance is fully concrete and executable: exact banned phrases named verbatim ("excited to announce", "game changer"), a hard naming rule ("ForgeCode", never "Forge"), a character budget, a lead-with-benefit rule, and a hashtag policy with the approved-tag list one reference away. As an instruction-only skill the guidance is copy-paste-checkable with no gaps; anchor 5 applies per the code_vs_instruction_skills note (example posts live in the mandated style guide).

Workflow Clarity

The three-step sequence (understand the feature via guided sub-questions -> draft per style guide -> present for approval) is clear and each step is well-defined. "Present for approval: show the post and ask if the user wants tweaks before finalizing" is an explicit feedback loop, and the referenced style guide adds a finalizing checklist. Not a destructive/batch operation, and the simple-skill exception applies; anchor 5 fits.

Progressive Disclosure

A short overview body with a single one-level-deep reference (references/style-guide.md), which was verified to exist and to contain exactly what is claimed (tone, vocabulary, approved hashtags, example posts). It is clearly signaled twice (workflow step 2 and a dedicated Reference Files section with a one-line description of its contents). Matches anchor 5 ("Clear overview with well-signaled one-level-deep references").

Specificity

"Generate a Twitter/X post highlighting a Forge feature" names the domain plus one concrete action, but stops short of enumerating several specific actions (drafting, tone constraints, hashtag policy are only in the body). This matches anchor 3 ("Names domain and 1-2 concrete actions, but not comprehensive") rather than 4, which requires a list of several specific actions.

Completeness

Explicitly answers both: "Generate a Twitter/X post highlighting a Forge feature" (what) and "Use when the user asks to write a tweet, create a Twitter post, or promote a ForgeCode feature on social media" (when, with concrete trigger phrases). Matches anchor 5 exactly; anchor 4 would require the 'when' clause to be less explicit or specific, which it is not.

Trigger Term Quality

"Use when the user asks to write a tweet, create a Twitter post, or promote a ForgeCode feature on social media" provides good natural coverage ("tweet", "Twitter post", "promote", "social media") but misses common variations like "X post", "post about", or "share on X". Anchor 4 ("Good keyword coverage; a few natural terms missing") is the best fit; not 5 because synonym coverage is incomplete, not 3 because the included terms are ones users would naturally say.

Distinctiveness Conflict Risk

A clear niche (social media posts for ForgeCode product features) with distinct triggers ("tweet", "Twitter post", "promote a ForgeCode feature"). Minimal overlap with generic writing or documentation skills; matches anchor 5 ("Clear niche with distinct triggers; minimal conflict risk").
