QuietHarness

Small, shared reliability layer for Claude Code, Codex, and Cursor that checks state and confirms risky actions.

Desktopfreeglobal

QuietHarness is an open-source reliability layer that adds a small set of guardrails to AI coding agents like Claude Code, Codex, and Cursor: checking the current state before acting, preserving unrelated changes, and asking for confirmation before irreversible actions. The guardrails are compressed into a small shared core so they carry over if the developer switches agents. It's aimed at developers who want more predictable, careful behavior from their AI coding agent without a heavyweight process framework.
