The Prompt
Task
Use @Asana/Search TasksName it "Asana/Search Tasks" and call it with @Asana/Search Tasks to find tasks older than 90 days with no recent activity. Categorize each as: still relevant (needs update), should be closed, or should be merged with another task. Use @Asana/Add CommentName it "Asana/Add Comment" and call it with @Asana/Add Comment to request owner confirmation and @Asana/Update TaskName it "Asana/Update Task" and call it with @Asana/Update Task to tag stale tasks for review.
Input
The user provides:
- Their Asana project or workspace to clean up
- The staleness threshold (optional, defaults to 90 days)
- What to do with stale tasks: "report only", "tag for review", or "tag and comment"
Example: "Find all tasks in the Product Backlog that haven't been updated in 90 days and tag them for review"
Context
Finding Stale Tasks
- Use @Asana/Search TasksName it "Asana/Search Tasks" and call it with @Asana/Search Tasks to find tasks not modified in the last 90 days (or the user's threshold)
- Filter out completed tasks — only look at open tasks
- Check for tasks with no comments, no assignee changes, and no status updates
- Note the last activity date for each stale task
Categorization
Review each stale task and categorize it:
Still Relevant (Needs Update):
- Task has clear requirements and fits current project goals
- Someone would benefit from picking this up
- Recommend: Add a "needs review" tag and comment asking the owner for an update
Should Be Closed:
- Task is outdated, superseded by other work, or no longer aligned with project direction
- Original requester is no longer on the project
- Similar work has already been completed elsewhere
- Recommend: Comment with the reason and suggest closing
Should Be Merged:
- Task duplicates or overlaps with another open task
- Multiple tasks describe different aspects of the same piece of work
- Recommend: Link to the other task and suggest merging
Applying Actions
- Use @Asana/Update TaskName it "Asana/Update Task" and call it with @Asana/Update Task to add a "needs review" tag or custom field to flagged tasks
- Use @Asana/Add CommentName it "Asana/Add Comment" and call it with @Asana/Add Comment to explain why each task was flagged:
- "This task hasn't been updated in [X] days. Is it still relevant? Please update or close."
- "This task appears to overlap with [other task]. Consider merging."
- "This task may be outdated — [reason]. Suggest closing if no longer needed."
- Never close or delete tasks without explicit user confirmation
Safety Guidelines
- Always show the user a full report before taking any actions
- Never close tasks — only flag and comment
- Keep comments professional and constructive
- If unsure about a task's relevance, categorize as "needs review" rather than "should be closed"
- Process in batches and confirm after each batch
