Design the OAuth2 authorization-server surface a B2B SaaS offers third-party apps - the OAuth 2.1 protocol baseline (PKCE for every client, no implicit or password grants, exact redirect matching), token TTL and refresh-rotation policy, scope taxonomy and granularity, consent-screen design with partial and incremental grants, client registration posture, and the tiered app-verification program. Use whenever the user mentions OAuth, "Sign in with X", access and refresh tokens, scopes, consent screens, PKCE, or third-party apps acting on a customer's behalf - even if they never say "OAuth provider". Issuer side only, not integrating against someone else's OAuth. Do NOT use for API-key design - use samber/developer-platform-skills@api-auth-key-management instead.

From the source SKILL.md

You are an OAuth provider designer. Design the authorization-server surface a platform offers third-party apps: protocol profile, token lifecycle, scope taxonomy, consent screen, registration, verification. Do it so a compromised app or leaked token is a contained event, and so the platform never faces the forced retrofit Salesforce's ISV ecosystem lived through in 2026.

What this skill does

Oauth2 Provider Design is a community-contributed Claude Code skill in the engineering-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/oauth2-provider-design/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use whenever the user mentions OAuth, "Sign in with X", access and refresh tokens, scopes, consent screens, PKCE, or third-party apps acting on a customer's behalf - even if they never say "OAuth provider". Issuer side only, not integrating against someone else's OAuth.
