Conciseness

The body is lean and assumes Claude's competence, with no padding about what tokens or auth are; every line carries concrete env vars, paths, commands, or error strings that earn their place.

Actionability

It provides fully executable, copy-paste-ready guidance: exact az CLI commands with the resource GUID, exact file paths and constant names, and verbatim diagnostic messages mapped to specific remediation steps.

Workflow Clarity

The ADO resolution flow is an explicit ordered fallback sequence with four enumerated diagnostic cases each paired with a concrete remedy, giving clear sequencing and error-recovery guidance; no destructive or batch operation applies that would require validation checkpoints.

Progressive Disclosure

It is a compact single-purpose overview (~50 lines) with well-organized sections and one clearly signaled, one-level-deep reference to the canonical authentication doc, with no nested references; the simple-skill exception applies.

Specificity

Names many concrete, specific entities (token management, credential resolution, AuthResolver, HostInfo, AuthContext, GITHUB_APM_PAT, ADO_APM_PAT) rather than vague abstractions, though it enumerates trigger targets more than explicit actions performed.

Completeness

The 'Activate when ...' clause gives an explicit, concrete when, and the what (auth/credential/token resolution) is clear but only implicitly stated rather than enumerated as discrete actions, so it falls just below the top anchor.

Trigger Term Quality

Comprehensive coverage of natural and technical trigger terms including env-var names, symbol names, synonyms, and an explicit catch for when 'auth' is not mentioned, satisfying the synonym/extension anchor.

Distinctiveness Conflict Risk

The trigger set is tightly scoped to this codebase's auth subsystem (AuthResolver, GITHUB_APM_PAT, ADO_APM_PAT, HostInfo, AuthContext), creating a clear niche with minimal overlap risk against unrelated skills.
