Show HN: Pu.sh — A Full Coding-Agent Harness in 400 Lines of Shell

Pu.sh / Hacker News·medium signal

A developer built Pu.sh, a complete coding-agent harness using only sh, curl, awk, and system primitives — no dependencies, under 500 LOC. It provides persistent sessions, letting you use an AI agent from the shell like a regular command. The minimalist approach resonated with HN (82 points, 21 comments), challenging the trend of increasingly complex agent frameworks with a zero-dependency alternative.
