What it does

This skill gives an AI agent a checklist-style guide for setting up OAuth 2.0 sign-in and access tokens correctly. OAuth is the standard that lets apps log users in or call APIs without handling passwords directly. Once installed, the agent can help choose the right flow for a web, mobile, single-page, or server-to-server app, walk through PKCE setup, recommend token lifetimes and rotation, and design scopes. It also includes Python scripts that can query an identity provider's public discovery page and check its settings against security best practices.

Great for

  • Developers implementing or reviewing login and API authorization in a web, mobile, or SPA app
  • Security engineers auditing an identity provider's OAuth configuration in a lab or authorized environment
  • Students learning how PKCE, client credentials, and token rotation fit together

Skip it if

  • Auditing a live production identity provider or third-party service without written authorization, since the audit script sends requests to whatever issuer URL it is given
  • Replacing a vetted identity library or managed service: the guidance is generic and does not cover your specific provider's quirks, so mistakes in hand-written token handling remain possible

Try asking

  • “Help me choose between Authorization Code with PKCE and Client Credentials for my mobile app and backend service.”
  • “Walk me through implementing PKCE in my single-page app, including code_verifier and code_challenge generation.”
  • “Review my OAuth scope design and suggest least-privilege scopes for read and write access to orders.”
  • “Check the discovery endpoint of our test identity provider for insecure grant types like implicit or ROPC.”

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Point the audit scripts only at a test or lab issuer you own or have written permission to test, and read the script before running it.
  • Ask the agent to explain each recommendation against your actual identity provider's documentation, since the skill's guidance is generic.
  • Treat generated code as a starting point and have it reviewed by someone experienced in OAuth before deploying to production.
