auth0 — Claude Code plugin: features and installation

# auth0

Auth0 skills for setting up authentication, migrating from other providers, implementing Multi-Factor Authentication (MFA) and passwordless passkey (WebAuthn) login, framework-specific SDK integrations and CLI.

## Installation

**Via Codex / ChatGPT desktop:**

Add the repository marketplace from `.agents/plugins/marketplace.json` to the
Plugins UI, then install **Auth0**. It tracks the published `main` snapshot. The
public plugin directory requires submission and approval through the
[OpenAI plugin submission portal](https://platform.openai.com/plugins).

**Via Claude Code:**

First, add the Auth0 marketplace if you haven't already:

```bash
/plugin marketplace add auth0/agent-skills
```

Then install the plugin:

```bash
/plugin install auth0@auth0-agent-skills
```

**Via Skills CLI:**

```bash
npx skills add auth0/agent-skills/plugins/auth0
```

**Via an Agent Plugins-compatible client:**

Load the `plugins/auth0` directory using the client's plugin install flow.
[Agent Plugins](https://agent-plugins.org/) defines the portable package format,
not a universal install command.

**Via Antigravity:**

```bash
agy plugin install plugins/auth0
```

**Via Gemini CLI:**

Install from a local clone — `gemini extensions install` expects a manifest at
the repository root, and this manifest lives at `plugins/auth0/`:

```bash
gemini extensions install ./plugins/auth0
```

## Forcing the skill with `/auth0`

Auto-detection is reliable on capable models. On a smaller/faster model in a
session with **many** other skills installed, the assistant can occasionally
miss the trigger — most often on open-ended *questions* ("how do I…?") rather
than direct instructions. When that happens, name the skill explicitly:

```
/auth0 how do I configure brand colors in Auth0?
```

Naming the skill removes the selection step entirely, so it always activates.

## Migrating from the individual skills

Earlier versions shipped one skill per SDK/framework (`auth0-react`,
`auth0-nextjs`, `express-oauth2-jwt-bearer`, …). These are now **consolidated
into the single `auth0` skill** above, which routes to the same guidance by
detecting your framework. Plugin/marketplace installs swap in the consolidated
skill on the next update with nothing to do. **If you referenced an old skill by
name** — in your `CLAUDE.md`, another skill's `requires.skills`, or any
instruction file — those names no longer exist and the reference will dangle;
replace them with `auth0`. See the [repository README](../../README.md#migrating-from-the-individual-skills)
for full migration details.
