Conciseness

The ~72-line body is dense and operational throughout — no section explains concepts Claude already knows, and even the opening four-failure-modes paragraph sets up the taxonomy the scripts implement rather than padding. Dates like '--as-of 2026-10-31' are example flag values, not stale-prone time-sensitive guidance, and the control citations (PCI DSS 8.2.6, PCAOB AS 1105.10) are the substance of the skill.

Actionability

Three fully executable commands with real flags and example filenames, outputs chained between steps ('--diff diff.json --campaign campaign.json'), a per-script exit-code table, and a note that all scripts support '--help', '--sample' and '--output json'. This matches the copy-paste-ready anchor covering the common cases, with no gaps since required policy flags are shown explicitly.

Workflow Clarity

A numbered 3-step workflow with each step explained, explicit validation via documented exit codes, and a dedicated five-condition 'The gates block on (exit 4)' checklist. 'Prove removals by re-export' provides the remediation feedback loop. Checkpoints are explicit rather than implicit, matching the top anchor; the workflow is read-only analysis so the destructive-operation cap does not apply.

Progressive Disclosure

The body is a lean overview with a well-signaled 'References and assets' section; all 10 referenced bundle files (3 scripts, 3 references, 4 assets) exist in the bundle and each entry carries a one-line scope description. References are one level deep, citing external standards rather than nesting further skill files.

Specificity

The description enumerates multiple concrete third-person actions covering the full capability set: 'Diffs the HR roster against account exports', 'tests the campaign for coverage, self-review, unremoved revokes and rubber-stamping', and 'maps every exception to the controls it breaks'. This matches the comprehensive-coverage anchor rather than the 'several actions, minor gaps' anchor below it.

Completeness

It explicitly answers both questions: the 'what' is the three concrete actions (diff, campaign tests, control mapping) and the 'when' opens with 'Use when preparing or running a user access review' and enumerates five distinct concrete trigger scenarios. Both are explicit with concrete trigger phrases, matching the top anchor rather than the merely-present 'when' of the 4 anchor.

Trigger Term Quality

Natural user phrases are present — 'user access review', 'leavers', 'orphaned or ownerless service accounts', 'auditor's access-control request', plus five framework names (SOC 2, ISO 27001, PCI DSS, HIPAA, NIST 800-53). It falls short of the top anchor because common synonyms such as 'access recertification', 'offboarding' or 'deprovisioning' are missing, though coverage is well beyond the 'some relevant keywords' anchor.

Distinctiveness Conflict Risk

The niche is clear — running and evidence-testing the joiner/mover/leaver and access-review process itself — but the framework names (SOC 2, ISO 27001) are triggers that whole-programme compliance readiness skills would also claim, leaving minor overlap risk with closely related skills. It is well beyond the 'somewhat specific' anchor, but not the minimal-conflict top anchor.
