Implement authentication and authorization with supported mechanisms. Triggers on "implement auth", "实现认证".

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

# Auth Implementation

## When to use

- Implement authentication and authorization with supported mechanisms.

**Not for:** security-review for auditing existing security.

## Steps

1. Identify actors, trust boundaries, session lifecycle and provider; check current official guidance.

2. Implement the chosen flow, secure credential handling, expiration and revocation without custom cryptography.

3. Enforce server-side ownership and tenant authorization, including login, logout and session renewal behavior.

4. Test real allowed and denied paths, expiration, revocation and cross-user access in an isolated environment.

## Verify

- Tests cover authentication and object authorization; sessions use supported mechanisms and no secrets leak.

## References

How to install

The exact contents, by fingerprint

mdr add int2t05/engineering-skills/auth-implementation@sha256:592144f1d47cc06f

The line at the top of this page pins the label git:20261015.f440cbb, 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.
