Cio

Customer.io (cio)

This is the installable bootstrap skill for agents using the Customer.io CLI. Run cio prime first; it prints the compact CLI reference, JSON output rules, command syntax, schema introspection, pagination, error shapes, and skill-reading guidance.

If cio is not installed, fetch current installation instructions from the README:

curl -fsSL https://raw.githubusercontent.com/customerio/cli/main/README.md

Use runtime references instead of copying large playbooks into this skill:

• cio schema for commands, flags, generic API routes, and payload shapes.
• cio skills to list currently available Customer.io reference skills.
• cio skills read cli for skills unique to the CLI (auth/login, integration, onboarding/new user setup); read it for the full index.
• cio skills read <skill> for the specific service-hosted reference needed.
• cio api <path> for API coverage that is not wrapped by a bespoke command.

Common routing:

• Builder/startup setup, signup, sandbox, first app integration,

transactional proof, billing activation checks, and go-live start with cio prime and cio skills read cli.

• Existing Journeys resources such as campaigns, segments, templates,

customers, newsletters, and subscription topics should use cio skills read fly-api.

• CDP Pipelines, sources, destinations, identify, track, page, and screen work

should use cio skills read cdp-api.

• Design Studio email/component editing should use

cio skills read design-studio.

• Analysis workflows, campaign review, goal-based segments, and Liquid should

use cio skills read recipes.

Credential rule:

• Service account tokens (sa_live_...) authenticate the CLI and account-level

management operations.

• Do not embed service account tokens in customer application code.
• Use CDP source write keys for SDK identify/track/page/screen ingestion.
• Use workspace-scoped App API keys for backend transactional sends.
