Pi coding agent wins fans: a minimal harness you customize with skills, extensions and self-built workflows
JnBrymn · x · 2026-09-12
Data scientist JnBrymn shares his multi-model coding flow: ChatGPT as daily driver, jumping to the minimal Pi coding agent (pi.dev) when hitting usage windows, plus a skill he wrote that periodically pulls the pareto frontier across top providers to auto-update his model picks. Pi positions itself as a minimal agent harness: extensions, skills and AGENTS.md support, a tiny system prompt for token efficiency, four modes (interactive, print/JSON, RPC, SDK), message rewind/branching, Enter to steer mid-run, and packages shareable via npm or git — asking Pi to build missing features on the fly rather than shipping sub-agents or plan mode.
