authentication SKILL.md skillA
authentication from nahid-sparktales/agent-dispatcher is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add nahid-sparktales/agent-dispatcher/authentication@git:20260919.a0d4f55Pins git:20260919.a0d4f55 in mdr.lock. Pin the fingerprint instead.

Establish who the caller is — session cookies, bearer tokens, refresh, and OAuth/OIDC flows — and put each where it belongs. Use when adding or changing login, logout, signup, session handling, token issuance or refresh, an identity-provider integration, or when a request arrives with a credential nobody validates. Not for deciding what an authenticated caller may then do (that is authorization), not for the login screen's design, and not for hand-rolling crypto.
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 Authentication answers one question: **who is making this request?** Every answer it produces is an input to authorization, never a substitute for it. A skill that conflates the two produces an app where being logged in is the only permission that exists. ## When this fires A credential is issued, accepted, refreshed or revoked. Adding login, wiring an identity provider, introducing an API key or token, changing session lifetime or cookie flags. It does not fire for "this user should not see that" — that is authorization. ## Procedure 1. **Find the mechanism that already exists before adding one.** Grep for session middleware, an auth library in the dependency manifest, existing cookie names, a provider SDK, `Authorization` header handling. Most "add auth" tasks are "extend auth". Two parallel auth systems is how a bypass gets built. 2. **Name the client type, in writing, before any code.** First-party browser app → server session with a cookie. Third-party, native or mobile client → bearer token. Service to service → client-credentials token or mutual TLS. This choice determines everything below; making it …

How to install
mdr add nahid-sparktales/agent-dispatcher/authentication@sha256:0f7bf7e789cecff1The line at the top of this page pins the label git:20260919.a0d4f55, 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.
