## Why evidence_attach_file is rated Medium

The name 'evidence_attach_file' most directly implies a Write operation—creating or modifying a record by attaching a file. Without a description, confidence is moderate. The blast radius is medium because attachment to evidence records could have downstream effects on audit trails or legal proceedings, but the operation itself is reversible (file can typically be detached/replaced).

## Use case

AI agents use evidence_attach_file to create or update resources in AbraFlexi, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your AbraFlexi environment.
