WHAT IT DOES

What resolve_comment_thread does on Postman

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

WHY IT NEEDS A POLICY

Why resolve_comment_thread needs a policy

This tool modifies the state of comments (marking them as resolved) which is a reversible write operation. It changes data but does not delete or destroy anything, nor does it execute arbitrary code or move money. The scope is limited to comment metadata within what appears to be a Postman API documentation/testing platform.

From the tool's definition Tool name 'resolve_comment_thread' and description 'Resolves a comment and any associated replies' indicate modification of comment state/status.
