Lumi: app and UI for Hermes Agent

Native Rust and GPUI desktop app for Claude Code, Gemini CLI, Hermes, Crush, Codex and Cursor

What Lumi does

The user-facing piece is lumi-gpui, a single binary with ten task surfaces in a left-rail layout: Chat, Cowork, Code, Creative, Memory, Analytics, Sprint, Plans, Agents and Settings. Chat shows streamed text, tool-call bubbles, permission modals and slash commands. Sprint is a five-lane kanban board grouped by epic, story and task, and Analytics rolls up turns, tokens and cost per team with an audit log.

Underneath is a Cargo workspace of lumi-* crates covering storage, memory, dispatch, policy, audit, pricing, cron and skills. The README says a lead Claude Code instance is launched per team with an MCP configuration pointing at in-process servers for memory, dispatch, personas, sprints, permissions, skills and browsing. State lives under ~/.lumi-lyra/, including per-team memory and a JSONL audit log. The app is run from source with cargo.
