Kitsune Engine: The Agent-Native Browser Engine

Kengine (KitsuneEngine) represents a paradigm shift in how AI agents interact with the web. While most agents today rely on fragile workarounds like screen-scraping or the Chrome DevTools Protocol (CDP), Kengine provides a native execution layer where agents "own" the browser. Built entirely in Rust for memory safety and performance, the engine allows for an "Agent Swarm" to orchestrate complex, multi-tab workflows, such as parallel flight booking, job applications, or deep research, with full DOM access and session continuity. A key innovation is the integration of a zero-exposure local vault, which allows agents to handle sensitive data via Argon2-encrypted tokens rather than plaintext. The architecture includes Human-in-the-Loop (HIL) gates for irreversible actions, ensuring safety during autonomous operations. By moving the agent logic into the engine itself, Kengine eliminates the latency and inaccuracy of traditional browser automation, providing a robust, sandboxed environment where multiple specialized agents can collaborate on difficult, long-horizon tasks.
