auth-implementation-patterns SKILL.md skillA

This file is byte-identical to the first copy the registry indexed, one of 4 indexed copies. Same content hash, so the same checks give both the same grade.

auth-implementation-patterns from rudycity/superagent is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add rudycity/superagent/auth-implementation-patterns@git:20260626.019dba9

Pins git:20260626.019dba9 in mdr.lock. Pin the fingerprint instead.

Master authentication and authorization patterns including JWT, OAuth2, session management, and RBAC to build secure, scalable access control systems. Use when implementing auth systems, securing APIs, or debugging security issues.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Authentication & Authorization Implementation Patterns

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

## When to Use This Skill

- Implementing user authentication systems
- Securing REST or GraphQL APIs
- Adding OAuth2/social login
- Implementing role-based access control (RBAC)
- Designing session management
- Migrating authentication systems
- Debugging auth issues
- Implementing SSO or multi-tenancy

## Core Concepts

### 1. Authentication vs Authorization

**Authentication (AuthN)**: Who are you?

- Verifying identity (username/password, OAuth, biometrics)
- Issuing credentials (sessions, tokens)
- Managing login/logout

**Authorization (AuthZ)**: What can you do?

- Permission checking
- Role-based access control (RBAC)
- Resource ownership validation
- Policy enforcement

### 2. Authentication Strategies

**Session-Based:**

- Server stores session state
- Session ID in cookie
- Traditional, simple, stateful

**Token-Based (JWT):**

- Stateless, self-contained
- Scales horizontally
- Can store claims

**OAuth2/OpenID Connect:**

- Delegate authentication
- Social login (Google, GitHub)

How to install

The exact contents, by fingerprint

mdr add rudycity/superagent/auth-implementation-patterns@sha256:1fc61d6074ace3d3

The line at the top of this page pins the label git:20260626.019dba9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
