Quality

Content

86%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A well-structured, token-efficient instruction skill: lean per-platform guidance, a clear clarify→adapt→deliver workflow, and a pre-delivery quality checklist, all appropriately inlined with no unnecessary bundle files. The gaps are the absence of a worked example demonstrating platform-native adaptation and the lack of a remediation step when the Quality Gate fails.

Suggestions

Add one compact worked example in the Repurposing Flow: a single source idea shown as a platform-native X post and a LinkedIn post, so the 'adapt, don't cross-post' rule is concrete rather than only stated.

Extend the Quality Gate with a remediation loop, e.g., 'If a draft fails: re-check the hook against the first-3-seconds / first-line rule, cut to one idea, then re-run the gate,' to give the validation checkpoint a feedback path.

Tighten actionability further by replacing a few abstract directives with measurable checks (e.g., 'hooks are strong and specific' → 'the hook names a concrete result, number, or mistake in the first line').

DimensionReasoningScore

Conciseness

The body is lean and assumes Claude's competence throughout — no explanation of what the platforms are or how social content works; every section ("Core Rules", per-platform bullets, "Repurposing Flow", "Quality Gate") carries only directive content. This matches 'Lean and efficient; assumes Claude's competence; every token earns its place'; there is no padded or over-explained passage that would pull it to a 4.

5 / 5

Actionability

The guidance is concrete and instruction-specific rather than abstract: "first 3 seconds must interrupt attention", "refresh the visual every 20-30 seconds", "extract 3-7 atomic ideas", "keep links out of the main body unless necessary". Per the scoring note this is an instruction-only skill, so absent code is not penalized, but it stops short of the top anchor ('specific examples cover the common cases') because it contains no worked example — e.g., one source idea rendered as an X post vs. a LinkedIn post — which would make the platform-native distinction fully concrete.

4 / 5

Workflow Clarity

There is a clear sequence with an explicit validation checkpoint: "First Questions" (gather inputs) → "Core Rules" → "Repurposing Flow" numbered cascade ("1. anchor asset ... 5. align CTAs") → "Deliverables" → "Quality Gate" ("Before delivering: each draft reads natively..."). This satisfies 'Clear sequence with most checkpoints present'. Not a 5 because the Quality Gate is a checklist without a feedback loop — nothing says what to do when a draft fails the gate (which rule to revisit, how to re-check) — so the error-recovery element of the top anchor is missing.

4 / 5

Progressive Disclosure

No bundle files exist (references/, scripts/, assets/ are absent) and none are needed: the body is compact (~85 lines), organized under clear headers ("When to Activate", "Platform Guidance", "Repurposing Flow", "Deliverables", "Quality Gate"), and all inline content is core guidance that any invocation would need — nothing belongs in a separate reference file. Per the rubric's simple-skill exception, well-organized sections with no need for external references score 5; there are no nested or buried references that would lower it.

Description

95%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 description: it explicitly answers both what the skill does and when to use it, in third-person voice, with comprehensive natural trigger terms spanning named platforms and artifact types. The only weakness is that the capability verbs are slightly generalized ('create', 'adapt') compared to enumerating the distinct actions the body actually supports.

DimensionReasoningScore

Specificity

"Create platform-native content systems" and "one source asset adapted cleanly across platforms" name the domain and several concrete deliverables ("social posts, threads, scripts, content calendars", "repurposed multi-platform campaigns"), matching the anchor 'Lists several specific actions; minor gaps in coverage'. It falls short of a 5 because the verbs remain at 'create/adapt' — it does not enumerate distinct actions as comprehensively as the top anchor (e.g., drafting, scheduling, hook writing are only implied by artifact names).

4 / 5

Completeness

The 'what' is explicit ("Create platform-native content systems for X, LinkedIn, TikTok, YouTube, newsletters, and repurposed multi-platform campaigns") and the 'when' is an explicit, concrete trigger clause ("Use when the user wants social posts, threads, scripts, content calendars, or one source asset adapted cleanly across platforms"), exactly matching the anchor 'Clearly and explicitly answers both what AND when with concrete trigger phrases'. Not a 4 because the 'when' is already fully specific rather than merely present.

5 / 5

Trigger Term Quality

Natural user phrasing is comprehensively covered: platform names ("X, LinkedIn, TikTok, YouTube, newsletters") plus artifact synonyms ("social posts, threads, scripts, content calendars") plus the repurposing phrasing "one source asset adapted cleanly across platforms". This matches the anchor 'Comprehensive coverage of natural terms including synonyms' — a user asking for a thread, a TikTok script, or to repurpose a podcast would hit these terms; there are no file extensions relevant to this domain.

5 / 5

Distinctiveness Conflict Risk

It carves a clear niche — multi-platform social content creation and repurposing — with distinct triggers (platform names, "threads", "content calendars") that no generic writing or document skill would claim, matching 'Clear niche with distinct triggers; minimal conflict risk'. Voice is third person ('Create...'), so no specificity penalty applies. Not below 5 because the overlap with a hypothetical generic copywriting skill is minor given the explicit platform list.
