Summary
The update_task tool exposes a followers parameter, but passing an array of user GIDs returns Bad Request. This is because the Asana REST API handles followers through dedicated endpoints rather than the task update endpoint:
Current behavior
update_task(task_id="123", followers=["456"]) → Bad Request
The followers field on update_task is accepted as a parameter but the API rejects it since Asana doesn't support modifying followers via PUT /tasks/{task_gid}.
Expected behavior
Either:
- New tools
asana_add_task_followers and asana_remove_task_followers that map to the dedicated Asana endpoints, or
- The
update_task tool internally detects the followers field and routes it to the correct addFollowers endpoint
Option 1 is cleaner and more aligned with the Asana API design.
Proposed tool signatures
asana_add_task_followers(task_id: string, followers: string[])
asana_remove_task_followers(task_id: string, followers: string[])
Where followers is an array of user GIDs (e.g. ["1205570277083468"]).
