WHAT IT DOES

What link_document_to_issue does on Huly

AI agents use link_document_to_issue 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 link_document_to_issue is rated Medium

Linking a document to an issue is a reversible write operation that creates or modifies data (establishing a document-issue relationship). It does not execute arbitrary code, delete data, or involve financial transactions. The severity is medium because improper linking could clutter or misdirect issue tracking, but the operation is easily reversible and has limited blast radius.

From the tool's definition Tool description states 'Link a Huly document to an issue. The link appears in the issue' — this creates a new association/relationship between entities and modifies the issue's state by adding a link.
