Of the agent, By the agent, For the agent
A small set of focused, open-source dev tools built by hang-in. On one track, tools for working with coding agents. On the other, real-time graphics and physics. Both share a name, an aesthetic, and a refusal to bloat.
Track
Tools for working with coding agents - orchestrating, routing, visualising, and grounding them.
One surface for Claude Code, Codex, Gemini, and local engines.
A desktop client for orchestrating subscription-tier CLI coding agents inside a single Plan → Dev → Review workflow. Cross-vendor blind review, branch/adopt, CLI-first.
Self-hosted reading assistant for finance and narrative PDFs.
Markdown parser that preserves page and block coordinates, hybrid BM25 + vector search to surface relevant sections instantly.
Small-talk TUI for local-LLM personas.
A Hawkes-intensity engine decides who speaks when; a silence gate and RRF decide when the room goes quiet.
Trigger-driven dynamic context loading for code-aware agents.
A production-hardened fork of CTX. Modulized, packaged, regression-guarded, and instrumented for real-world Claude Code hook use.
Bridge local LLMs into Claude and Codex surfaces.
A small adapter for routing local model servers into the same surface area as cloud CLI tools.
Ship code horizontally.
A tool for distributing code work across parallel surfaces. Lightweight, dependency-free.
A macOS companion for the tuna family.
Native menu bar utilities that surface tunaFlow and sibling tools where the work happens.
Burn your tokens - visually.
A live visualisation of token spend across sessions. Built to make usage legible.
Burn your tokens, again.
The simpler sibling of tunaChat. A reference impl for token-stream visualisation.
Minimal Rust TUI for managing and connecting to SSH hosts.
A fast terminal interface for hosts defined in ~/.ssh/config. Filter, jump, and connect without leaving the keyboard.
Recall your second brain - conversations with AI agents, turned into a local wiki.
Organise and search chats with AI agents as a personal knowledge base. Self-hosted, local-first, and built to surface the right context when you need it.

WebGPU-first simulations. Solar systems, gravity, black holes. Built for the browser, run on your GPU.
WebGPU solar system - the lighter sibling.
A cinematic Three.js solar system with synchronized server clocks, orbit camera, and per-body shading. Powers sol.d9ng.co.kr.
