WHAT IT DOES

What remove_tags does on Pinako AI Bridge

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

WHY IT NEEDS A POLICY

Why remove_tags needs a policy

This tool removes specific tags from a node but preserves all other tags. It modifies metadata in a targeted, reversible way (tags can be re-added), making it a Write operation. The blast radius is low since it only affects tag metadata and is a no-op for tags not present.

From the tool's definition 'Filters specific tags off a node, preserving the rest. No-op for tags not present.'

remove_tags stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
