Tools

8 tools agents can invoke

Show the active authentication state. Reports the authenticated user and account, the workspaces the current OAuth token is allowed to access, and whether an agent service-account JWT can be minted. Use this to diagnose auth errors.
Delete a resource via the Customer.io API (DELETE only). Always run with dry_run first to preview. Use cio_schema to find the correct path.
Print LLM-ready instructions for using the Customer.io API. ALWAYS call this first in a new task — it contains the authoritative, version-specific rules for how to drive the API via the other cio_* tools.
Read from the Customer.io API (GET only). Use cio_schema first to find the correct path and placeholders. Workspace routing is enforced server-side via the caller's OAuth token.
Introspect the Customer.io API schema. Use this to discover endpoints before calling cio_read_api / cio_write_api / cio_delete_api — never guess paths or field names. Pass no query to list resources; pass a resource name ('campaigns') to list its endpoints; pass 'resource.method' ('campaigns.list'), 'METHOD /path', or '/path' for endpoint detail.
List available agent skills — task-specific instruction manuals maintained by Customer.io (routing rules, required params, multi-step workflows).
Read the full content of a specific agent skill. Paths look like 'campaigns' for the main skill or 'campaigns/examples.md' for a sub-file — see cio_skills_list for available paths.
Write to the Customer.io API (POST, PUT, or PATCH). Always run with dry_run first to preview. Use cio_schema to find the correct path, method, and body shape.

Customer.io FAQ

How do I improve a ChatGPT Plugin's discoverability?

The levers are the listing surface agents actually read: names, descriptions, keywords, tool metadata, and registry health. Which lever matters depends on where discovery breaks, which is what continuous measurement shows.
