Diagnose first, give one next step. Assume the user knows nothing about OAuth or pools.

## Core rules

- **One step at a time.** One command or action, not branches.
- **Diagnose before advising.** Run checks first, then choose the path.
- **Auth commands go in a separate terminal.** Never ask for tokens or codes in chat.
- **Explain what, not internals.** Do not mention pool.json, PKCE, token endpoints, or auth hooks.
- **After any add/import:** remind them to restart the app, then press Ctrl+T to choose a model.
- **Any model can run this.** `oauth-pool-helper.sh` works even on free models.

## Workflow

### Step 1: Diagnose

Run in parallel: `oauth-pool-helper.sh check` (pool state) and `claude auth status --json 2>/dev/null` (CLI auth).

### Step 2: Choose the path

#### Path A — no accounts exist

If `claude auth status --json` shows `loggedIn: true` with `pro` or `max`, say: "You're already logged into Claude CLI with a **{subscriptionType}** account ({email}). Run in a separate terminal: `oauth-pool-helper.sh import claude-cli`"

Otherwise, ask which provider they have and run the matching command:

| Provider | Subscription | Command |
|----------|-------------|---------|
| Anthropic | Claude Pro or Max ($20-100/mo) | `oauth-pool-helper.sh add anthropic` |
| OpenAI | ChatGPT Plus or Pro ($20-200/mo) | `oauth-pool-helper.sh add openai` |
| Cursor | Cursor Pro ($20/mo) | `opencode auth login --provider cursor` |
| Google | AI Pro or Ultra ($25-65/mo) | `oauth-pool-helper.sh add google` |

Anthropic/OpenAI/Google: browser opens → authorize → paste code → restart app. Cursor: browser opens → authorize → tokens saved automatically → restart app.

#### Path B — accounts exist and are healthy

Say: "Everything looks good. Your pool has N account(s) and will auto-rotate if one hits rate limits."

- **One account:** suggest adding a second — `oauth-pool-helper.sh add <provider>`.
- **CLI account not in pool:** suggest importing — `oauth-pool-helper.sh import claude-cli`.

#### Path C — accounts exist but have problems

Give one fix at a time:

- **EXPIRED / INVALID (401) / auth-error**: Re-add — `oauth-pool-helper.sh add <provider>`.
  - Cursor exception: expired tokens are normal (IDE re-reads them) — only flag Cursor if status is also `auth-error`.
- **Missing refresh token**: Remove first (`oauth-pool-helper.sh remove <provider> <email>`), then re-add.
- **All rate-limited**: Offer to reset: `model-accounts-pool` tool `{"action": "reset-cooldowns"}`.

#### Path D — manage existing accounts

| Action | Command |
|--------|---------|
| Remove | `oauth-pool-helper.sh remove <provider> <email>` |
| List | `oauth-pool-helper.sh list` |
| Rotate | `model-accounts-pool` tool `{"action": "rotate"}` |

### Step 3: Verify

After any add, import, remove, or re-auth: run `oauth-pool-helper.sh check` and report the result.
