The file

We split this skill into the rules it gives an agent

2 rules. 0 are common, 1 is distinctive, and 1 is very specific to this project.

  • 0

    Common

    Most of the 13 edited versions we read keep these.

  • 1

    Distinctive

    This author's own choices. Worth a look.

  • 1

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Very specific:

    If detailed examples are required, open resources/implementation-playbook.md.

    line 30
  2. Distinctive:

    Never log secrets, tokens, or credentials.

    line 34

“Common” is measured: kept by at least 6 in 10 of the 13 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Authentication & Authorization Implementation Patterns

Build secure, scalable authentication and authorization systems using industry-standard patterns and modern best practices.

Use this skill when

  • Implementing user authentication systems
  • Securing REST or GraphQL APIs
  • Adding OAuth2/social login or SSO
  • Designing session management or RBAC
  • Debugging authentication or authorization issues

Do not use this skill when

  • You only need UI copy or login page styling
  • The task is infrastructure-only without identity concerns
  • You cannot change auth policies or credential storage

Instructions

  • Define users, tenants, flows, and threat model constraints.
  • Choose auth strategy (session, JWT, OIDC) and token lifecycle.
  • Design authorization model and policy enforcement points.
  • Plan secrets storage, rotation, logging, and audit requirements.
  • If detailed examples are required, open resources/implementation-playbook.md.

Safety

  • Never log secrets, tokens, or credentials.
  • Enforce least privilege and secure storage for keys.

Resources

  • resources/implementation-playbook.md for detailed patterns and examples.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
