Conciseness

The same goth.UseProviders registration code appears three times nearly verbatim (registration pattern, per-provider setup, and multiple-providers sections), and scope/callback guidance repeats across sections — several padded, duplicated sections beyond what a competent reader needs. Not score 3 because the duplication is wholesale section-level repetition rather than occasional over-explanation; not score 1 because the content is code-dense with no concept padding.

Actionability

Concrete, copy-paste-ready Go for provider registration, tenant options, provider-name override, and env vars, plus numbered console/portal steps and error-name-keyed troubleshooting ('redirect_uri_mismatch', 'invalid_client'). Not score 5 due to minor gaps: examples swallow errors ('user, _ := gothic.CompleteUserAuth(w, r)') and no complete route/handler example ties the flow together.

Workflow Clarity

Console and portal configuration steps are clearly numbered per provider, and the 'Common Issues' section gives error-recovery guidance for the failure modes most likely to occur. Not score 5 because there is no explicit end-to-end verification checkpoint (e.g., confirm the callback round-trip works after registration); not score 3 since the setup sequences and reactive recovery guidance are genuinely clear. Not capped at 3 since this is configuration guidance, not a destructive or batch operation.

Progressive Disclosure

References are clearly signaled ('For detailed Google setup steps, see references/google-oauth-setup.md') and one level deep, but the references/ directory does not exist — both cited files are dangling — and the detailed setup content that belongs in them (portal steps, scope tables) is inlined in SKILL.md. Scored against the actual bundle structure: well-organized but broken navigation and misplaced detail. Not score 4 because nonexistent referenced files are more than a minor organization gap; not score 2 because the body itself is well-sectioned and the reference intent is explicit.

Specificity

The description names its domain concretely ('specific OAuth provider configuration in Goth') with provider-specific triggers, but never states what actions the skill itself performs — capabilities appear only as quoted user phrases ('add a provider', 'configure google oauth'), which is implied rather than explicit capability listing.

Completeness

The 'when' is explicit and rich ('This skill should be used when the user asks to...'), but the 'what' is only weakly implied through the trigger clause 'needs help with specific OAuth provider configuration in Goth' — the description never states what the skill provides (e.g., setup guidance and code patterns for Goth providers).

Trigger Term Quality

Strong natural trigger phrases users would actually say ('add a provider', 'set up microsoft login', 'azure ad authentication', 'add social login') with good synonym coverage across providers, but a few natural variations are missing (e.g., 'sign in with Google', 'Goth login', 'Azure AD').

Distinctiveness Conflict Risk

Names a clear niche ('specific OAuth provider configuration in Goth') with library-specific triggers, giving minimal conflict risk with unrelated skills; minor overlap remains with sibling Goth skills (e.g., goth-fundamentals) and the fairly generic 'add a provider' trigger.
