`@sendblue/cli` is a Node CLI that creates a Sendblue account, provisions an iMessage-enabled number, and sends messages. It is the fastest way to text from a shell, script, or Claude Code hook — no API client, no webhook server, no credentials in env vars. Credentials live at `~/.sendblue/credentials.json` (mode `600`) and Node.js 18+ is required.
Sends fire-and-forget iMessage/SMS notifications to the user's phone when long-running tasks, agent turns, or scheduled jobs finish via Sendblue CLI.
Sends iMessages for real-time user input and status notifications during Claude Code sessions. Use ask_user to wait for responses on decisions or clarifications; notify_user for non-blocking updates.
Sends emails and manages Resend platform resources (domains, broadcasts, templates, webhooks, API keys, logs) via the `resend` CLI. Supports React Email .tsx templates. For shell scripts, CI/CD pipelines, or direct terminal use.

# or one-shot:
npx @sendblue/cli <command>
sendblue setup runs interactively by default. For CI/scripts, run it in two phases — the first call sends an 8-digit verification code by email, the second consumes it.
sendblue setup --email you@example.com # sends code
sendblue setup --email you@example.com --code 12345678 \
--company my-co --contact +15551234567 # completes setup
| Flag | Notes |
|---|---|
--email | Email address |
--code | 8-digit verification code (from the email) |
--company | Lowercase, hyphens/underscores, 3–64 chars |
--contact | First contact, E.164 |
sendblue send +15551234567 'Hello from Sendblue!'
sendblue messages --inbound --limit 20
Phone numbers must be E.164 (+ + country code + digits, no spaces or dashes).
On the free plan, a contact must text your Sendblue number once before outbound sends to that contact will work. After sendblue setup ... --contact +15551234567, have that contact send any text to the printed Sendblue number, then run sendblue contacts to confirm verification.
| Command | Purpose |
|---|---|
sendblue setup | Create account, verify email, set company name, add first contact |
sendblue login | Log in to an existing account |
sendblue send <number> <message> | Send an iMessage |
sendblue messages [--inbound|--outbound] [-n <number>] [-l <count>] | List recent messages |
sendblue add-contact <number> | Register a contact |
sendblue contacts | List contacts and their verification status |
sendblue status | Account/plan info |
sendblue whoami | Show current credentials and verify validity |
long_running_thing && sendblue send +15551234567 "✅ done: $(date)"

Stop hookTo text yourself at the end of every agent turn, register a Stop hook in settings.json that shells out to sendblue send. Defer the actual hook wiring to [[update-config]] and the trigger logic to [[sendblue-notify]] — this skill only owns the CLI invocation.
