AI Agent Engineer β building harnesses, MCP servers, and orchestration tools for AI coding agents.
Licensed first-class architect (Japan) turned agent engineer: 20+ years in construction, overseas assignments, product development, and systems engineering.
- π€ I design harnesses and guardrails for AI coding agents β Claude Code, Codex, and multi-agent orchestration on Windows
- ποΈ Domain Γ AI: I hold Japanese first-class architect and construction management licenses, and build MCP servers that stop LLMs from hallucinating building codes and real-estate law
- πͺ I care about the Windows-native developer experience β most agent tooling assumes Unix; mine doesn't
- βοΈ I write about AI coding workflows in Japanese on Substack and Zenn
| Project | What it does |
|---|---|
| winsmux | Windows-native terminal multiplexer for inter-agent communication β tmux-style orchestration without WSL (Rust) |
| kbd-signal | Status lamp for Claude Code / Codex sessions using VIA-compatible keyboard RGB β glance at your keyboard, know your agent's state (Python) |
| building-standards-act-mcp | MCP server for the Japanese Building Standards Act via the e-Gov API β verifies statutes at the source so AI answers cite real law (TypeScript) |
| antigravity-orchestra | Orchestration template pairing Antigravity with Codex (PowerShell) |
| shield-harness | Security-first harness for AI agents, hardened against prompt-injection style attacks (JavaScript) |
All my Zenn articles are available in English (auto-translated) β just add ?locale=en:
- tmux on Windows without WSL: pane splitting and parallel AI agents with Rust-made psmux
- Hermes Agent complete build guide: your own always-on AI agent on a VPS
- Stop searching your notes yourself β Hermes Agent reads Obsidian as its memory
More on Zenn (Japanese / English) and Substack (Japanese).
π¬ DMs open on X β happy to talk AI agent tooling, Windows dev experience, and architecture Γ AI.
