  title: Composio Discover and Execute a Tool
  summary: Browse toolkits, list the tools they expose, and execute one tool for a user.
  description: >-
    The canonical Composio agent loop. The workflow lists the available
    toolkits, narrows to the tools belonging to a chosen toolkit, fetches the
    full schema of a specific tool to learn its input parameters, and then
    executes that tool against a connected account for a user. Every step spells
    out its request inline so the flow can be read and executed without opening
    the underlying OpenAPI description.
