Conciseness

The body is dominated by lean, concrete MCP call blocks, but the 'Resource Types' table partially duplicates scope/operation information already demonstrated in the steps, and passages like 'This returns all platform permissions. Use this to understand what permissions can be assigned via roles' could be trimmed. This matches 'Efficient; minor instances of over-explanation that could be trimmed' — it is not level 5 because a few tokens do not earn their place, and not level 3 because there is no genuinely unnecessary concept explanation.

Actionability

Every operation is a concrete, copy-paste-ready MCP tool call with named parameters (e.g., the create user_group body with identifier, name, description, users), and the Examples section maps common requests ('Create a service account for CI automation') to specific actions. This matches 'Fully executable; copy-paste ready code or commands; specific examples cover the common cases' — the only gap, a missing get-service_account example, does not affect common-case coverage.

Workflow Clarity

Steps 1–5 give a clear sequence, and validation guidance exists in Performance Notes ('Verify user email addresses and group identifiers before making changes', 'List existing groups and service accounts before creating to avoid duplicates') with troubleshooting covering error recovery (e.g., 'Try searching by email address instead of display name'). It is not level 5 because the destructive delete operations lack inline checkpoints and post-operation verification, and not level 3 because pre-change verification steps are explicitly present rather than absent.

Progressive Disclosure

No bundle files exist, and the single-file body is well-sectioned (Instructions, Resource Types, Relationship to /manage-roles, Examples, Performance Notes, Troubleshooting) with the /manage-roles cross-reference clearly signaled. This matches 'Good structure; most content is appropriately placed; references mostly clear; minor organization gaps' — at ~173 lines with some step/table redundancy, it is not the lean, fully-split structure of the level-5 anchor, but well above the poorly organized level-3 anchor.

Specificity

The description lists multiple concrete actions — 'List and search users', 'create and manage user groups for team-based access', 'create service accounts for API automation', 'view available permissions' — comprehensively covering the skill's scope. This matches the anchor 'Lists multiple specific concrete actions; comprehensive coverage' and exceeds the level-4 anchor, which expects only several actions with gaps.

Completeness

Both questions are explicitly answered: the 'what' via concrete capability statements and the 'when' via 'Use when asked to list users, create a user group, manage service accounts, check who has access, or set up team permissions' plus an explicit trigger-phrase list. This matches the anchor 'Clearly and explicitly answers both what AND when with concrete trigger phrases'; level 4 would require the 'when' to be less explicit.

Trigger Term Quality

'Trigger phrases: list users, user group, service account, who has access, team permissions, add user to group, create service account' provides comprehensive coverage of natural terms users would actually say, matching the anchor for comprehensive natural-term coverage including phrasing variations. It is not the level-4 anchor because few natural terms are missing — 'add user to group' and 'who has access' capture common colloquial phrasings.

Distinctiveness Conflict Risk

The description is scoped to 'Harness users, user groups, and service accounts via MCP' — a clear niche — and adds explicit disambiguation: 'Do NOT use for role assignments or resource groups (use manage-roles instead)'. This matches the anchor 'Clear niche with distinct triggers; minimal conflict risk'; level 4 would involve minor overlap risk with closely related skills, which the explicit manage-roles redirect preempts.
