Platform engineer · tooling for AI coding agents
Claude Code & Codex harnesses, supervision, observability — on top of 15+ years of software and infrastructure
📍 Warsaw, Poland · remote OK

Claude Code Codex CLI Agent Skills LinkedIn CV

🤖 Agent tooling — what I build now

Project What it does
🌳 agent-monitor
stars		 A live tree of every Codex and Claude Code session, subagent and teammate in a repo — across worktrees, with model, effort, task and status
🔁 agent-retrier
stars		 Auto-resume Claude Code or Codex after a usage limit or a refused turn. One shell script, no tmux, no daemon
🧭 harness-supervisor
stars		 One supervision process for many repos: shared skill, role routing, durable recovery state, leases for host resources, merge queue
🎮 game-maker
stars		 Build any game from a description and references with a fleet of builder / critic / judge agents
🎨 harness-pixelart
stars		 Real hand-drawn-style pixel art from an agent: craft-checked sprites and animations with game-ready exports

Built for both Claude Code and Codex · agent-monitor and agent-retrier install with brew install a0s/<name>/<name>
