Cua Driver Adds Privacy-Conscious Cross-Session Action History

Cua released an early preview of Computer History for Cua Driver, its open-source tool that lets AI agents operate apps on macOS, Windows and Linux. Cua describes it as an encrypted, local record of the actions agents took through Cua Driver, so a new session can recover useful context from earlier work. Without such a record, an agent starting fresh has no memory of what an earlier session already clicked, opened or failed at. Cua calls it the first open-source Computer History. It arrived days after OpenAI documented a ChatGPT feature with the same name, which gives ChatGPT and Codex context about the person's recent work, with controls to pause it or exclude apps and websites.

Cua's version is narrower by design. Its preview guide says the feature is off by default, needs a nightly build, and records only actions performed through Cua Driver, not unrelated desktop activity. Each entry holds fixed fields such as time, opaque session and action identifiers, the capability used, the target app's identifier and categorized outcomes. The guide says it never stores screenshots, typed text, keystrokes, clipboard contents, window titles, URLs, file paths or raw tool arguments and results. Records are encrypted with a key held in the operating system's credential store, kept for seven days by default, and never sent over the network. An authorized agent can query up to 200 events but cannot enable, delete or export the history or get the key. The guide also notes that what an agent reads can enter its model's context.

Only the first post of Cua's announcement thread was collected, and the guide describes the preview as it stands in Cua's repository now, so details may differ from the August launch.
