## What it does

The skill drives Mixpanel access through `auth_manager.py`. Every subcommand prints a single JSON object, and the agent parses it and reports back in plain language. Before running the bundled scripts you set `PLUGIN_ROOT` to the absolute path of the installed `mixpanel-headless` plugin. The script sits at `python3 $PLUGIN_ROOT/skills/mixpanelyst/scripts/auth_manager.py`.

Routing covers `session`, `account list`, `account add`, `account use`, `account login`, `account test`, `project list` and `project use`. Some branches are a single call; `account add` is a guided wizard that collects a name, a type and a region before handing over a command. Responses carry a `state` of `ok`, `needs_account`, `needs_project` or `error`. Errors also go to stdout with exit 0, so you can parse them without `try/except`.

Secrets stay out of the conversation. The skill never asks for passwords or API secrets and never passes them as CLI arguments, where they would show up in the process list. For a service account the user runs `mp account add <name> --type service_account -u <username> -p <project_id> -r <region>` themselves and types the secret into a hidden prompt. Browser login defaults to the `us` region, so EU and India users need `--region eu` or `--region in` explicitly.

## Install

### Codex (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add openai/plugins --skill mixpanel-auth -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/mixpanel-auth/SKILL.md` — For all projects use ~/.agents/skills/

### Claude Code

1. **Skills CLI (Vercel)**
```bash
npx skills add openai/plugins --skill mixpanel-auth -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/mixpanel-auth/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/mixpanel-auth/

### Cursor

**Manually: put the files in place**
- File: `.cursor/skills/mixpanel-auth/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install openai/plugins mixpanel-auth
```

2. **Manually: put the files in place**
- File: `.github/skills/mixpanel-auth/SKILL.md`

### Gemini CLI

**Platform CLI**
```bash
gemini skills install https://github.com/openai/plugins --path plugins/mixpanel-headless/skills/mixpanel-auth
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/mixpanel-auth/SKILL.md` — The legacy .windsurf/skills/ path still works

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/openai/plugins/tree/HEAD/plugins/mixpanel-headless/skills/mixpanel-auth/SKILL.md

## When to use it
- check which Mixpanel account is active right now
- add a service account without exposing the secret in chat history
- switch to another project or workspace
- run browser OAuth login and pick up the token
- verify credentials before firing off queries

## Example prompts
- show the current Mixpanel session
- list accounts and mark the active one
- switch to the team account

# Mixpanel Authentication Management

You manage Mixpanel credentials by shelling out to `auth_manager.py`. Every
subcommand emits exactly one JSON object to stdout — parse it and present the
result conversationally.

Before running bundled scripts, set `PLUGIN_ROOT` to the absolute path of the installed
`mixpanel-headless` plugin directory.

**Script path:** `python3 $PLUGIN_ROOT/skills/mixpanelyst/scripts/auth_manager.py`

**Schema:** Every response has `schema_version: 1` and a discriminated `state`
of `ok` | `needs_account` | `needs_project` | `error`. Errors emit JSON to
stdout (exit 0) so you can `json.loads` unconditionally — no try/except needed.

## Security Rules (NON-NEGOTIABLE)

- **NEVER ask for secrets (passwords, API secrets) in conversation** — they would be visible in history
- **NEVER pass secrets as CLI arguments** — visible in process list
- For account creation, guide the user to run `mp account add <name> --type service_account -u <username> -p <project_id> -r <region>` themselves — this prompts for the secret with hidden input

## Routing

Parse `$ARGUMENTS` and route to the appropriate subcommand. With no
arguments, run `session`.

### "login"

For first-time setup, the frictionless one-shot path is `mp login`. It
runs the right auth flow for the environment, derives the account name
from `/me`, and pins a default project. Tell the user to run:

```bash
mp login
```

Region behavior is auth-type-specific:
- `service_account` and `oauth_token` paths: probes `us → eu → in` and
  uses the first 200.
- `oauth_browser` path (the bare-`mp login` default): commits to `us`
  unless the user passes `--region eu` or `--region in`.

Optional flags they may want:
- `--name NAME` — override the derived account name
- `--region us|eu|in` — set the region explicitly (required for EU / India browser users)
- `--project ID` — skip the project picker
- `--service-account` — force the SA path (requires `MP_USERNAME` + `MP_SECRET` in env)
- `--token-env VAR` — force the static-bearer path (reads token from `$VAR`)
- `--no-browser` — print the authorization URL instead of launching a browser

After the user confirms they ran it, verify with `account test`:
`python3 $PLUGIN_ROOT/skills/mixpanelyst/scripts/auth_manager.py account test`

### No arguments or "session"

Run: `python3 $PLUGIN_ROOT/skills/mixpanelyst/scripts/auth_manager.py session`

Switch on `state`:
- **`ok`** — show one line: "Active: `account.name` → project `project.id`"
  (add workspace `workspace.id` if non-null). Mention that
  the account-list and project-list workflows in this skill exist if the user wants to switch.
- **`needs_account`** — no account configured. Show the first
