A personal coding agent built in ClojureScript + Bun, featuring a terminal UI (TUI), a WebSocket server hosting multiple rooms, and a browser-based web client — all sharing the same pure event handlers.

Highlights

One state atom per process. All logic is pure handlers (fn [state event]) → {:state :effects}; side effects run only in a dedicated effect interpreter.
Everything is an event — prompts, agent output, commands, dialogs, room switches, and renders all flow through the same dispatch loop. The WS wire protocol is those same event maps as EDN.
Three assemblies, one codebase — standalone TUI, WS server + TUI client, and a Replicant-based web client (with offline localStorage caching) are all compositions of the same handlers over different transports.
Pluggable providers — Claude Agent SDK and Ollama.
Data-driven extensions — each extension is a plain data map (:handlers :fx :tool-gate :commands :system-prompt …), composed at assembly time. Includes a knowledge base, web/perplexity search, GTD tasks, a permission gate, plan mode, and more.
Built-in tools — bash, read, write, edit, grep, find, ls, exposed to the agent via an MCP tool bridge.

Build

npm install    # install shadow-cljs + the Claude Agent SDK
bb build       # compile CLJS → JS (node TUI/server)
bb web:build   # compile the browser web client
bb test        # compile and run tests
bb tasks       # list all available tasks

Requires Babashka (bb) and Bun.

Dependencies hosted on a private registry

Two dependencies are pulled from the author's self-hosted Gitea and are not publicly reachable. To build from a clean checkout, mirror them to a host you control and update the URLs:

clj-ui-framework — a cross-target UI component library (deps.edn, docs/frontend.md)
tmux-dev — dev-loop tmux helpers used by the bb tasks (bb.edn)

Configuration

Copy .env.example to .env and fill in values if you want optional Pushover notifications. Agent auth uses ~/.pi/agent/auth.json OAuth tokens or the ANTHROPIC_API_KEY environment variable.
