Documentation

README

Excerpt

Execute Spec in Fork

Turn one approved SPEC READY into a disposable Codex execution task. Keep product decisions in the planning task, keep implementation logs in the fork, and return evidence to the planning task automatically.

Require a launchable contract

Before creating anything:

Find the latest completed SPEC READY block and apply later user corrections.
Require it to route to forked execution, fit one reliable implementation session, and contain no unresolved product decisions. Use /to-tickets or /to-goal when it does not.
Require the current harness to expose native Codex App task tools for forking, messaging, reading, naming, pinning, and archiving.
Require /codex-task-messenger to be installed and its v2 protocol available.

This is the opening of the README. Read the full README on GitHub.
