WHAT IT DOES

What find_and_replace_doc does on VaultAssist

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

RISK

Why find_and_replace_doc is rated Medium

This tool modifies existing document content by replacing text throughout a Google Doc. It is reversible in principle (edits can be undone via version history) but has a high blast radius because a poorly scoped find-and-replace could corrupt large portions of a document. It fits the Write category as it creates/modifies data, not Destructive since it doesn't delete documents outright.
