Sendblue CLI

Overview

@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.

When to Use This Skill

• Use when the user wants to text a phone number from a script, shell, hook, or agent turn (e.g. "text me when X finishes", "ping my phone", "notify on completion").
• Use when the user mentions sendblue as a CLI/binary or asks to set up the @sendblue/cli package.
• Prefer this skill over [[sendblue-api]] when the work happens in a shell context, one-shot script, cron job, or agent hook.
• Reach for [[sendblue-api]] instead when writing application code that integrates Sendblue, receiving inbound webhooks, or needing features the CLI does not expose (send styles, reactions, group messages, status callbacks, media uploads).
