Projects

agent-harness (2026–, Rust / Nix)

One Nix configuration for the hooks, skills, and permission rules of Claude Code, Codex, Devin, Hermes Agent, and pi. External skill and hook bundles such as Herdr and moshi plug into the same configuration. Design decisions are recorded in the design doc and ADRs. Runs daily in my dotfiles.

  • reflex-state (2026, TypeScript) — Execution state for Pi coding agents, tracked outside the main LLM. Inspired by SKILL.state.
  • book-agent (2025) — A Claude Code command that turns notes from technical books into sub-agent definitions. Zenn
  • LLM-chatbot (2023–2024, team project) — A LINE chatbot that recommends products with an LLM, supported by the Fukuoka Mitou program. My commits
