Case study: Giving agents UI memory cuts operation time by half
naykip · reddit · 2026-08-25
The author added persistent UI structure memory for agents operating real software. In a Telegram Desktop task, the first run took 110 seconds/9 calls, while the second run dropped to 59.9 seconds/4 calls. Savings came from the agent not needing to re-locate the search box and composer fields.
Core Architecture:
- Live Map: Real-time window structure map (dies with the window)
- Change Stream: Stream of changes (avoids re-reading to see action results)
- Per-App Dictionary: Persistent dictionary keyed by app and version (stores rules like search box != composer)
- Replayable Paths: Reusable operation paths (e.g., "open chat with NAME")
Safety Design:
- Consent Gate: Send/submit/apply stops for human approval; paths cannot learn around it.
- Non-persistent: Never stores live handles, user data, or permission grants.
