# Task Activity

> Track every change to a task and roll back when needed

Every task keeps a complete record of what happened to it—who changed what, when, and why. You can see the full timeline and even undo changes by rolling back to earlier states.

## Viewing task activity

1. Click any task to open its details
2. Look for the **Timeline** or **Activity** tab
3. Scroll through the history of changes

The timeline shows everything in reverse chronological order, with the most recent changes at the top.

## What gets tracked

Every modification creates an activity entry:

| Change type         | What's recorded                               |
| ------------------- | --------------------------------------------- |
| **Status**          | From "To Do" → "In Progress" → "Done"         |
| **Priority**        | Low, Medium, High, Urgent changes             |
| **Assignee**        | When someone takes over or hands off the task |
| **Due date**        | Date changes and removals                     |
| **Title**           | Renames and edits                             |
| **Description**     | Content updates                               |
| **Archive/restore** | When tasks are archived or brought back       |

### Who made changes

Each entry shows exactly who made the change:

* **Team members**: Profile picture and name
* **AI coworkers**: AI avatar and name
* **System**: Automated changes (like scheduled updates)

For AI changes, you'll also see which tool or action triggered the modification.

## Reading the timeline

### Compact view

By default, activity shows in a compact format:

* **Timestamp**: "2h" (2 hours ago), "5m" (5 minutes), "now"
* **Avatar**: Who made the change
* **Summary**: "Updated status, priority"
* **Badge**: Number of fields changed

Click any entry to expand it and see the full details.

### Expanded view

When you expand an entry, you see:

* **Exact timestamp**: "Nov 10, 2:30 PM"
* **Field-by-field changes**: Status: In Progress → Done
* **Before/after values**: Crossed-out old value, highlighted new value

## Rolling back changes

Made a mistake? You can undo task changes:

<Steps>
  <Step title="Find the change to undo">
    Scroll through the timeline to find the activity you want to revert.
  </Step>

  <Step title="Click Rollback">
    Hover over the entry—a rollback button appears on the right.
  </Step>

  <Step title="Confirm">
    Review what will change and optionally add a note explaining why.
  </Step>

  <Step title="Done">
    The task returns to its state before that change was made.
  </Step>
</Steps>

### What can be rolled back

* **Field updates**: Status, priority, assignee, dates, etc.
* **Description changes**: Content modifications

### What can't be rolled back

* **Task creation**: You can't un-create a task (archive it instead)
* **Already rolled-back changes**: Can't roll back a rollback

<Info>
  Rolling back creates a new activity entry, so there's always a complete audit trail. Nothing is hidden or deleted.
</Info>

## Activity from AI coworkers

When AI coworkers modify tasks, the activity timeline shows:

* Which AI made the change
* What tool was used (e.g., "task\_update")
* The AI's reasoning (if available)

This makes it easy to understand why changes happened, even when you weren't watching.

### AI-created tasks

Tasks created by AI coworkers show:

* "Created by \[AI name]"
* Which conversation or workflow triggered the creation
* All the initial field values

## Real-time updates

Activity updates live. If someone changes a task while you're viewing it:

* New entries appear at the top of the timeline
* No need to refresh
* You see changes as they happen

## Time tracking integration

If your workspace uses time tracking, time entries appear in the same timeline as other activity. You'll see:

* When time was logged
* How long the work session lasted
* Who tracked the time

This gives you a complete picture of both changes and effort.

## Filtering and searching

For tasks with lots of activity:

* **Scroll** through the timeline chronologically
* **Look at avatars** to find changes by a specific person
* **Read summaries** to identify particular types of changes
* **Check timestamps** to find activity from a specific period

## Activity retention

Trilo keeps task activity indefinitely. You can always see the complete history of a task from creation to present.

## Tips

<AccordionGroup>
  <Accordion title="Check activity before big changes">
    If you're about to make significant updates, scan the recent activity first. Someone else might already be working on it.
  </Accordion>

  <Accordion title="Use activity for handoffs">
    When handing a task to someone else, point them to the activity timeline. It's faster than explaining everything.
  </Accordion>

  <Accordion title="Trust the record">
    Activity can't be edited or deleted. If there's ever a question about what happened, the timeline is the source of truth.
  </Accordion>

  <Accordion title="Add notes when rolling back">
    The optional rollback note helps future you (and your team) understand why you undid a change.
  </Accordion>
</AccordionGroup>

## Troubleshooting

<AccordionGroup>
  <Accordion title="Activity isn't showing recent changes">
    Very recent changes might take a moment to appear. If you're editing rapidly, Trilo batches activity to avoid cluttering the timeline with every keystroke.
  </Accordion>

  <Accordion title="Rollback button is missing">
    Some activities can't be rolled back—like the initial creation of a task. The rollback button only appears for undoable changes.
  </Accordion>

  <Accordion title="AI changes don't show reasoning">
    Not all AI actions include detailed reasoning. If you need more context, check the conversation where the AI was working.
  </Accordion>
