Yardgoat Caboose
A planning and memory system for repositories worked on by AI agents.
Caboose gives a repository one roadmap that always answers three questions: where have we been, where are we, and where are we going. The repository itself remembers, so any agent, on any model, can pick up where the last session stopped.
You paste one line to your coding agent. It reads the specification, surveys the repository’s real history and drafts the roadmap, numbered plans, decision records and checks. Then it stops: nothing is carried out until you say so.
Caboose is the first public part of Yardgoat, a larger system still in development, and it stands on its own. The whole specification is at yardgoat.ai/caboose.
