Conciseness

The body is dense and assumes Claude's competence — no padding explaining known AWS or data-catalog concepts — but the bulk-revocation confirmation rule is restated in three places (the 'Bulk work' section, the authorisation table, and the Security considerations table), and the ~30-line MCP-vs-local file-resolution guardrail is runtime plumbing that could be trimmed. This sits between the 3 and 5 anchors, noticeably above the midpoint: efficient with identifiable trims rather than unnecessary explanation.

Actionability

The body gives exact command flags ('--decision-comment', '--request-reason'), exact --query paths with terminal status values ('items[].status' → 'COMPLETED', per-asset 'GRANTED'/'REVOKED'), and copy-paste probe commands, but the executable runbooks for the common operations (approve, revoke, audit) are delegated to the references rather than given inline. This matches the 4 anchor (concrete commands with minor gaps) rather than 5, since the common cases are not copy-paste ready from the body alone.

Workflow Clarity

The sequence is explicit — probe identity and domain, resolve the acting project from identity, route via the table, act, then verify — and the destructive/batch validation bar is fully met: the confirm-the-plan-then-revoke checkpoint before bulk revocation, poll-to-settlement with per-asset verification, the three-outcome verdict ('A failed call is not a zero'), and re-showing the plan if the subscription set changed. Clear sequence with explicit validation, feedback loops, and checklists: the 5 anchor.

Progressive Disclosure

The body is a genuine overview with a router table mapping each user intent to one of seven one-level-deep reference files, all of which exist in the bundle, with no nested (2+ level) references. Cross-cutting rules that must be read before any chapter are appropriately in SKILL.md while procedures are split into references — clear overview, well-signaled references, easy navigation: the 5 anchor.

Specificity

The description enumerates five concrete actions spanning the full lifecycle — 'requesting a subscription, approving or rejecting requests with a recorded decision, sharing a listing with a project, revoking one or many subscriptions, and confirming grant settlement' — plus the specific platform ('Amazon SageMaker Catalog supported by Amazon DataZone through catalog subscriptions over published listings'). This matches the comprehensive-coverage anchor, not the 4 anchor, because there are no minor gaps: grant, decide, share, audit, revoke and verify settlement are all named.

Completeness

It explicitly answers both questions: the 'what' is the first two sentences (the concrete operations), and the 'when' is an explicit 'Triggers on:' clause with concrete trigger phrases. This is the 5 anchor verbatim ('clearly and explicitly answers both what AND when with concrete trigger phrases').

Trigger Term Quality

The trigger list is composed of natural user phrasings with synonyms per operation: 'give another team access to a table', 'request access to a dataset', 'approve or reject an access request', 'who has access to this table', 'revoke access', 'bulk revoke', 'is the access actually gone'. Coverage is comprehensive across the natural variants users would actually say, matching the 5 anchor rather than the 4 anchor ('a few natural terms missing').

Distinctiveness Conflict Risk

The 'Not for:' clause disambiguates against every plausible neighbor by name — IAM/STS (aws-iam), S3 bucket policies (securing-s3-buckets), Clean Rooms (aws-cleanrooms), and catalog metadata/publishing/asset retirement (managing-data-catalog) — and the niche itself (catalog subscriptions over published listings) is distinct. Clear niche, minimal conflict risk: the 5 anchor.
