  title: Amazon EFS Inspect File System Topology
  summary: Describe a file system and enumerate its mount targets to audit its network topology.
  description: >-
    A read-only audit flow for Amazon EFS. The workflow describes a single file
    system to capture its lifecycle state and reported mount target count, then
    enumerates every mount target attached to it, surfacing the subnet,
    Availability Zone, IP address, and network interface for each. The result is
    a complete picture of where and how the file system is reachable, useful for
    audits and troubleshooting. Every step spells out its request inline so the
    flow can be read and executed without opening the underlying OpenAPI
    description.

  summary: Describe a file system and list all of its mount targets.
  description: >-
    Reads a file system's description and then lists its mount targets so a
    caller can audit the file system's lifecycle state and network reachability
    across subnets and Availability Zones.
  inputs:
    type: object
    required:
    - fileSystemId
    properties:
      fileSystemId:
        type: string
        description: The ID of the file system to inspect.
      maxItems:
        type: integer
        description: The maximum number of mount targets to return.
  steps:
  - stepId: describeFileSystem
    description: >-
      Describe the file system and confirm it exists, capturing its lifecycle
      state and reported number of mount targets.
