Cio

This wraps the Customer.io CLI for managing campaigns, broadcasts, segments, and CDP pipelines right from Claude. The standout move is `cio prime`, which dumps the entire API reference into context so you're not fumbling through help text. It handles three main flows: onboarding new users through account setup and first email send, integrating the SDK into an existing codebase with track and identify calls, and billing questions about plans and going live. If you're building on Customer.io or debugging `fly.customer.io` errors, this keeps you in the terminal instead of context switching to docs.
