punchtape is a state machine that makes your AI get the entire job done — start to finish, with every claim proven. Your words are taken down word for word; the machine runs every check itself, compares bytes, tells the agent what to fix, and records a signed finish only when everything stands. You read the result — you do not check anything yourself.
It is not another harness and not a plugin: it stands beside your project as the outside party. It works the same whether your agent sits in an IDE (Cursor, GitHub Copilot) or the terminal (Claude Code, Codex CLI), and doesn't care which frontier model stands behind it. Any language, any framework. Free, open source (MIT), fully offline, no account.
Getting started takes one line: paste "Read https://github.com/neurophant/punchtape/blob/main/docs/BOOTSTRAP.md and act by it" into your assistant — the agent installs the machine and sets everything up by itself. Then write your task in plain words; when every check stands, the machine records the verdict: done: true has to be earned.
