Open-source tooling for AI-assisted engineering, systems, and the occasional weird experiment. Built and maintained by @elijahr. Serious engineering, also fun.
spellbook- multi-platform harness for AI coding assistants: skills, hooks, and a shared MCP server across Claude Code, OpenCode, Codex, Gemini CLI, and ForgeCode.momus- AI code review as a GitHub Action. Works with any LLM (OpenRouter, Anthropic, OpenAI, Bedrock).heads-up-claude- Claude Code statusline with real-time token tracking. Written in Nim.headerkit- clang-based C/C++ header-parsing toolkit in Python with pluggable backends.soong- summons GPU instances for AI agent workflows.komputers- GPU compute in Rust over the Kompute Vulkan framework: safe wrapper, C++ FFI bridge, and hand-written GLSL compute shaders (matmul, parallel reductions). Experimental.audiomancer- MCP server for AI-assisted music production with TidalCycles.sonoscope- machine-listening audio-QA harness: analyzes audio and MIDI to check what your DSP actually produced.
Themes: AI developer tooling, MCP, systems, and audio.
