Codex Harnesses

codex-harnesses is a collection of practical harnesses for long-running, reliable, safe, and high-quality Codex-driven software development.

Codex should not be expected to succeed by intelligence alone.

This site explains how to use the repository as a selectively deployable harness kit:

  • durable project guidance with AGENTS.md
  • reusable workflows with skills
  • deterministic enforcement with hooks
  • explicit safety posture with policies
  • resumable task memory with ledgers
  • repeatable verification with scripts and CI

Start Here

If you are adopting the harnesses in a project:

  1. Read the User Guide.
  2. Pick a starting shape from Examples.
  3. Follow the Adoption Checklist.
  4. Run one small real task through the harness before expanding it.

Core Idea

Harnesses keep important behavior out of chat history. They make project guidance, repeated workflows, safety checks, task memory, and verification visible, versioned, reviewable, and testable.

This repository is not a multi-agent router. It is a harness collection.
