The Shopify CEO just endorsed an agent built by one developer in Austria over every funded AI coding tool on the market.
Pi has four tools. Read, Write, Edit, Bash. No MCP. No sub-agents. No plan mode. The shortest system prompt of any known agent harness.
OpenClaw, the agent that hit 145,000 GitHub stars and 21,000 live deployments in a single month, runs on Pi. Armin Ronacher, who built Flask and basically shaped Python web development, ported his entire workflow to it.
The kicker is what Tobi actually did with it. He told Pi to spawn Claude Code in a tmux session, reverse-engineer its tasks system, and rebuild it from scratch. Pi pulled it off, including the UX.
This is an agent studying another agent's product and shipping a clone in one session.
$400M in VC funding has gone into agent frameworks. Pi is beating them with four system calls and a package manager. When the CEO of a $100B company says "dawn of malleable software," the trade is to watch what Shopify builds next, because they just told you the architecture.
Pi is the most interesting agent harness.
Tiny core, able to write plugins for itself as you use it. It RLs itself into the agent you want.
I was missing cc’s tasks system and told it to spawn clause in tmux and interrogate it about it and make an implementation for itself. It nailed it, including the UX.
Clawdbot is based on it and now it makes sense why it feels so magical. Dawn of the age of malleable software.
