Software for the age of agents.

Since 2025 most of what I build either gives AI models real tools to work with, or measures and polishes what they produce. Below that: the game engine, the courses, the everyday tools, and an archive of what came before.

AI agents & MCP servers

Tools for a future where models do more of the work: servers that let an assistant drive professional software, a formatter for the Markdown and LaTeX they write, and a benchmark that checks whether code really scales the way it should.

Checks what code really costs★

TempoBench

Benchmark any command in any language over a sweep of input sizes, then let TempoBench fit the growth curve: O(n), O(n log n), O(n²)… with a confidence level and the reason for any doubt. It writes an HTML report and can turn the result into a narrated vertical video.

19,183×Miller–Rabin over trial division at n = 10¹⁶, one of nine algorithm races, each with both classes fitted correctly

Why it matters now: when an agent writes the code, a fitted growth curve is a quick, honest check that it scales.

Cleans up model output★

marklign

A Markdown formatter written in Rust that takes special care of display LaTeX. It joins orphaned operators into readable expressions and never leaves a line Markdown would misread: a lone = or - inside $$…$$ turns half an equation into a heading in most renderers.

Directing know-how for models · new★

VideoGenome

An open, renderer-independent specification for video-production expertise. Strong models write and refine blueprints for directing, pacing, sound and design; smaller models pick one and fill in the content, instead of reinventing film-making for every video. Pluggable tools (text-to-speech, ComfyUI, Blender over MCP) make the assets and an FFmpeg renderer assembles the cut.

A field guide to working with models

LLM Queries

A living knowledge base of prompts, agent workflows ("skills"), evaluations and local-model setup guides, around 66 documents. Each one is tracked in a registry that says when it is due for re-checking, because advice about models goes stale fast. It also holds an experimental benchmark for coding agents.

OpenCaption

A command-line tool in Go, built on whisper.cpp, that turns audio and video into SRT, VTT or JSON captions on your own machine. It runs on the GPU through CUDA, Metal or Vulkan, skips silence with voice-activity detection, and works through whole folders in batch mode.

AI is also how I build now. GitHub Copilot coding agents made about 925 of the 2,162 commits in the Standard of Iron engine, and about 245 of the 617 in the Lightpad editor.

A C++ game engine, from scratch

Not a game made in someone else's engine: the renderer, the simulation, the animation, the UI and the tooling are all written from scratch, and they ship together as a real-time strategy game.

Standard of Iron

A single-player real-time strategy game set in an altered Second Punic War. You command formations from above, or take direct control of a commander on the battlefield, while running a settlement economy and assaulting fortified positions. An eight-mission campaign runs from the crossing of the Rhône to Zama.
