Core modules
Leontes is built around a set of modules that work together — not a collection of disconnected features bolted on top of an LLM.
Watches your file system, clipboard, calendar, and active window. Triggers suggestions or actions without you asking. It notices before you do.
Reads application UI via Windows UI Automation — no screenshots, no pixel matching. Sees buttons and fields as structured code, not images.
A knowledge graph linking people, files, and projects. Say "send the quarterly report to Sarah" and it finds the right person, file, and channel from your history.
When the agent hits a capability gap, it writes a new tool class, compiles it, runs a test, and asks you to approve. Nothing runs without your sign-off.
Talk to it from your terminal or message it from your phone via Signal (E2E encrypted). Same context, same memory, same agent.
Core modules are being built. No release yet — but the architecture is solid, the scope is locked, and the code is public. Star the repo to follow along.
