WHAT IT DOES

What set_chat_message_pinned does on Huly

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

RISK

Why set_chat_message_pinned is rated Medium

This tool creates or modifies message metadata (pin status) reversibly. Users can toggle pins on and off, and the idempotent nature confirms no data is destroyed. This is a Write-category operation—data is changed but can be undone by unpinning. It does not read arbitrary data (Read), execute external code (Execute), permanently delete data (Destructive), or move financial value (Financial).

From the tool's definition Tool description states 'pin or unpin a top-level message' and is idempotent, indicating reversible modification of message state within a chat platform.
