Action Audit Trail
What is Action Audit Trail?
After an agent has acted - especially across multiple steps or over extended periods - users need a clear, reviewable record of what happened. This is fundamentally different from traditional undo/redo because agentic actions may span multiple systems, occur asynchronously, and have cascading consequences. A user who discovers their agent has sent 15 emails, rescheduled 3 meetings, and updated a spreadsheet needs to quickly understand what happened, why, and how to reverse specific actions. The Action Audit Trail provides a timestamped log grouped by task with plain-language descriptions, reversibility color-coding (green/amber/red), selective undo capabilities, and before/after diff views for document modifications. This extends source attribution from citing information sources to citing action sources.
Problem
After an agent has acted across multiple steps or systems, users need a clear, reviewable record of what happened. Traditional undo/redo doesn't work for agentic actions that span multiple systems, occur asynchronously, and have cascading consequences.
Solution
Provide a timestamped, structured log of every agent action grouped by task, with plain-language descriptions, reversibility color-coding, selective undo for individual actions, and before/after diff views for modifications.

Guidelines & Considerations
Implementation Guidelines
Default view should be a timeline grouped by task, not a raw chronological log. Users think in goals, not timestamps.
Color-code by reversibility: green for fully reversible, amber for partially reversible, red for irreversible actions.
Include a 'What changed?' diff view for document modifications - show before/after, not just 'edited file.docx'.
Allow filtering by action type, time range, and affected system for efficient review.
For high-volume agents processing hundreds of items, provide summary statistics alongside the detailed log.
Include export capability for compliance and team review contexts.
Support selective undo - let users reverse individual actions in a chain without undoing everything.
Design Considerations
Audit review rate: what percentage of users review the audit trail after agent actions
Selective undo rate: how often users undo individual actions indicates the trail is usable and valuable
Time-to-discovery: how quickly users identify and correct problematic agent actions
Balancing log detail with performance - storing every action at full fidelity has storage and rendering costs
Grouping actions by task requires the agent to maintain goal context throughout execution
Selective undo may have cascading effects - undoing step 3 of 5 may invalidate steps 4 and 5
Privacy implications of detailed action logging, especially for shared or enterprise environments
