⚙️ Precision Utility Guild

Small guild. Sharp tools.

Independent software studio building precise utilities, agent tooling, and the occasional unreasonably ambitious engine. Mostly TypeScript. Always tested.

🔨 On the workbench

Project What it is
DocForge Agent-grade document production — an MCP server that turns structured data into typeset PDFs via Typst. 24 templates, offline compiles, visual-regression-tested, plus Forge, a Slack agent that drives it.
Liquid Shadow Persistent operational memory for coding agents — a local-first repo brain over MCP. Stop making your agents grep.
Pathloom MCP telemetry analysis with epistemic rigor — it refuses conclusions your data hasn't earned.
Residual Runtime Runtime enforcement layer for AI and programmatic workflows.

🌐 Live in the wild

  • CalcConfig — build embeddable calculators and decision tools (pricing estimators, ROI walkthroughs) from configurable logic, deploy anywhere.
  • Hypervariant — a persistent workspace for living hyperbolic worlds. Non-Euclidean geometry you can keep.
  • Aliquot Watch — watching aliquot sequences chase their open problems in real time. Recreational number theory, running in production.

🧪 In the lab

Civilizational simulation at engine scale, and other projects whose north stars are deliberately out of reach. That's what keeps the workshop warm.
