Conciseness

The body is dense with non-obvious, Connect-specific directives and assumes Claude's competence about general concepts, but contains real padding: the full progress checklist is reprinted four times (once per step), and the Express public-preview disclosure requirements with the preview-changelog link are repeated nearly verbatim three times (Step 3 guardrails, Step 4a express/stripe, Step 4a express/application). This fits the 3 anchor ('mostly efficient but includes some unnecessary explanation or could be tightened'); it is more than the 'minor instances' of the 4 anchor.

Actionability

For an instruction-only skill the guidance is fully executable: exact question scripts with option labels ('"I have a URL" — user provides URL, then research it'), copy-paste warning text ('Warn: "Your platform fee might be below Stripe's processing fees..."'), specific grep patterns ('transfers.create, payouts.create', 'account.updated, capability, payout'), and exact config tuples to validate. This matches the 5 anchor's 'copy-paste ready... specific examples cover the common cases'; absence of code is not penalized per the rubric's instruction-skill note.

Workflow Clarity

Steps 0–6 are clearly sequenced with explicit validation checkpoints: 'Step 4a — Compatibility validation (MANDATORY before presenting recommendation)', '1f. Validate fee economics (ALWAYS runs...)', a fee-structure checkpoint gating Step 4, a visible progress checklist updated at each step, and a feedback loop for error recovery (BLOCKED combination → do not present → output fix → 're-run the recommendation with the corrected configuration'). This matches the 5 anchor (explicit validation, feedback loops, checklists).

Progressive Disclosure

The body is an orchestration overview with all eight references/ files existing, each referenced with a clear purpose ('Read <references/decision-matrix.md> and apply it...'), and references are exactly one level deep (no references/ files point further into the bundle). However, Step 4a's long enumeration of express/full compatibility rules duplicates rules already encoded in references/compatibility-matrix.md, and repeated preview-changelog links inflate the overview — content that belongs in the referenced file is inlined, which fits the 4 anchor ('most content appropriately placed; minor organization gaps') better than 5.

Specificity

The domain is named with specific concepts ("Stripe Connect configuration, charge patterns, Dashboard access"), but the skill's concrete actions are barely stated — only "for a recommendation" implies what it does, while scanning the codebase, discovery questions, compatibility validation, and plan generation are never mentioned. It names the domain plus roughly one concrete action, matching the 3 anchor ('names domain and 1-2 concrete actions, but not comprehensive') rather than 2, since the domain concepts are specific rather than generic.

Completeness

The 'when' is explicit and exhaustive ("Use this skill when the user asks about..."), but the 'what' is only weakly implied through "for a recommendation" — the description never states a capability like 'recommends the right Connect configuration and generates a plan'. Since scoring only what is explicitly stated, the weak 'what' keeps it at 3 (one half clear, the other weak/implied) rather than 4, which requires a solid statement of both.

Trigger Term Quality

Comprehensive natural-language coverage with abundant synonyms users would actually say: "marketplace, platform, multi-vendor store, gig platform, or subscription platform", "pay out sellers, vendors, or providers", "split payments, revenue sharing, multi-party payments", "onboarding or KYC", "white-label payments, or embedded payments". This matches the 5 anchor's requirement for comprehensive natural terms including synonyms; no common variation is obviously missing.

Distinctiveness Conflict Risk

The niche is clear and Connect-specific ("connected account Dashboard or responsibility configurations", "charge patterns") and even includes disambiguation ("not operational SaaS without payment routing"). However, a few triggers are broad enough to fire outside Connect contexts — "asks about payment flows" and "asks about onboarding or KYC for merchants" could match general payments or KYC questions — creating minor overlap risk, which fits the 4 anchor better than 5.
