The body is lean and information-dense — lists, tables, and a template — with no padding explaining concepts Claude already knows; every section earns its place.

Concrete, specific guidance throughout: a case-to-action classification table, an ordered remediation list ('refund only the affected charge or duplicate'), and a copy-paste output template. As an instruction-only skill, absence of code is not penalized since the guidance is actionable.

A clear five-step sequence (identify → classify → act → check gaps → handoff) with explicit pre-action checkpoints for destructive/revenue-impacting acts: 'Put the case into one bucket before acting' and 'verify the contract shape before taking action'.

A cohesive single-file skill with no bundle directories and no dangling references; content is organized into clearly signaled sections (When to Use, Guardrails, Workflow, Output Format) appropriate to its scope.

Lists multiple concrete actions — 'subscriptions, refunds, churn triage, billing-portal recovery, and plan analysis' — rather than vague language, matching the 3-anchor example structure.

Explicitly answers both what ('Operate customer billing workflows such as...') and when ('Use when the user needs to help a customer, inspect subscription state, or manage revenue-impacting billing operations'), with a clear 'Use when' trigger clause.

Natural terms a user would say are well covered: 'refund', 'subscription', 'billing', 'customer', 'Stripe', 'help a customer', 'inspect subscription state'. Not merely technical jargon.

A clear niche — customer billing operations via Stripe — with distinct revenue-impacting triggers unlikely to collide with other skills.
