cms-tokens-authentication

Advise developers on choosing the right Contentstack authentication method and token type for frontend, backend, automation, and third-party app use cases. Include security guidance, rate-limit awareness, and SSO considerations.

Use when developers ask about authentication, token types, API keys, rate limits, SSO integration, or credential security.

Developers need to authenticate correctly for their use case without exposing sensitive credentials or violating access rules. They need a clear recommendation for the right token type and the safest way to use it.

Recommends the correct token type for the scenario. Explains what is safe for client-side versus server-side use. Includes practical security guidance and credential-handling rules. Calls out rate-limit implications when relevant. Addresses SSO-specific constraints when applicable.

• Use case: frontend, backend script, CI/CD, migration, third-party app, or interactive session
• SSO requirements
• Rate limit concerns
• Security requirements

• Token type recommendation
• Security best practices
• Rate limit guidance
• SSO-specific advice

• What token should I use in my frontend app?
• What is the difference between a management token and an authtoken?
• How do I handle rate limits in my script?
• Can I use authtokens in an SSO-enabled organization?
• How many management tokens can I have per stack?

Identify the use case and runtime environment. Recommend the appropriate authentication method or token type. State what is safe for client-side versus server-side use. Add security and credential-handling guidance. Explain rate limits and backoff behavior if relevant. Include SSO constraints when applicable.

Be concise and direct. Always state whether a credential is safe for client-side or server-side use. Use bullets when comparing token types. Do not include raw secrets or example real tokens.

Read-only advisory skill. Do not create, modify, or delete tokens. Use documentation sources when needed. Prefer read-only tools only.
