Lean instructional prose with concrete code throughout; the explanatory sentences (e.g., bound-vs-in-force billing invisibility, premium drift) are niche PolicyCenter domain knowledge Claude does not already have, not generic concept padding.

Inline TypeScript uses real endpoints, headers, body shapes, and conditional logic (UW-issue filter, quote-expiry date check, drift threshold); helper functions are justified abstractions, with full implementations supplied in the implementation-guide reference.

A clear 7-step numbered sequence with explicit validation checkpoints before each risky transition (blocking-issue check, quote-expiry check, premium-drift check, renewal-window check), an error-handling table for feedback loops, and an Output checklist of required components.

SKILL.md is a focused overview that clearly signals one-level-deep references ("see [implementation guide](references/implementation-guide.md) and [API reference](references/API_REFERENCE.md)"), both of which exist as real files; detailed schemas and full function bodies are appropriately split out.

Lists the full concrete pipeline ("account→submission→quote→bind→issue→endorse→renew") plus specific failure paths ("underwriting issues blocking bind, quotes expiring before bind, referrals stuck pending approval"), matching the multiple-concrete-actions anchor.

Clearly states what it does (the lifecycle pipeline and failure paths) and when to use it via an explicit "Use when building outbound integrations..." clause plus a "Trigger with..." list, satisfying both what and when.

Explicit trigger block ("policycenter automation", "submission to bind", "policy renewal", "policy endorsement", "underwriting issue") covers natural phrases a user would actually say, matching the good-coverage anchor.

Narrow PolicyCenter policy-lifecycle niche with distinct, product-specific triggers; unlikely to fire for the sibling ClaimCenter skill or unrelated skills.
