    Repair Authentication & Authorization Failures

    Example session with this skill installed

    Our Next.js/Node SaaS logs users in correctly, but after token refresh some API calls return 401 while an old admin permission can remain cached after a role downgrade. We also saw one stale session retain access until its cache expired. Repair the auth lifecycle without weakening security or changing the intended role policy.

    • Read your context and instructions
    • Compiled the repair authentication

    The likely defect is not one login bug but a contract split between token/session freshness and authorization freshness. I would trace identity generation from login through refresh, middleware, permission lookup, tenant scope, caches, and logout/revocation. The repair should establish one authoritative session/token generation, invalidate or version cached authorization when roles change, bind authorization to the current tenant/user identity, and make refresh/revocation transitions atomic from the application perspective. Focused tests should cover refresh while requests are in flight, role downgrade during an active session, logout followed by replay, stale cache entries, wrong-tenant identity, expired credentials, and concurrent tabs. I would preserve existing security policy and never “fix” this by extending token lifetime, skipping verification, or broadening permissions. Repository edits/tests would only be claimed if actually performed.

    About this skill

    Repair Authentication & Authorization Failures is a bounded ToolForge Labs workflow. Diagnose and repair authentication and authorization failures across login, session/token validation, identity propagation, permission checks, tenant boundaries, logout/revocation, retries, and error handling. Works from repositories or partial logs/configuration. Produces bounded repair patterns and deterministic tests while preserving existing security policy and avoiding invented execution claims. It works from a full repository or partial supplied evidence. The skill separates verified facts from assumptions, preserves existing product/security policy, avoids invented execution claims, and returns concrete repair or review steps with deterministic validation or explicit remaining gaps.

    Requires access to auth middleware, policy files, or detailed traces. Does not handle physical hardware security modules or low-level kernel auth.

    What's inside

    Frequently Asked Questions

    This skill automates the identification and repair of broken token lifecycles, session revocation issues, and permission mismatches between authentication and authorization layers in your backend code.

    It is compatible with major AI agents that have codebase access, specifically those supporting backend environments where identity propagation, middleware, and API gateway logic are managed.

    To work effectively, you must provide the agent with access to your authentication middleware, identity provider configurations, or relevant diagnostic logs where the failures occur.

    Unlike general prompts that might suggest insecure bypasses, this skill enforces a 'no-bypass' rule, prioritizing fixes that uphold your security invariants and tenant isolation policies.

    You receive the core logic for diagnosing auth failures, a suite of deterministic security tests for edge cases like token expiry, and ongoing updates to address new OAuth2/OIDC patterns.

    Yes, it is specifically designed to handle complex identity propagation and tenant isolation across service boundaries, proxies, and microservice chains.
