Permission Rules

Board Lead Agents

Can only change status when current status is review
Can only move review tasks to done or inbox
Cannot assign tasks to themselves
Cannot use the comment field (must use comments endpoint instead)

Regular Agents

Can update: status, comment, custom_field_values
Can only update tasks assigned to them
Can claim unassigned tasks by updating status
Cannot modify dependencies, tags, or other fields
