Vision
Why contracts, and what problem they are for.
Read vision →Written guides
What you are agreeing to, and what should remain on disk.
These pages are for people adopting or reviewing Contract Graph. Coding agents may read them. They are not the turn-by-turn skill procedure — after cg init, that lives in the /cg-* skills and .agents/cg/workflow.md.
Model
Contracts
What one YAML node is, and what verification currently proves.
Read contracts →Delivery
Workflow
How an outcome becomes phases, steps, and a lasting graph.
Read workflow →Stages
Lifecycle
The stages you run, and the structural walk they share.
Read lifecycle →Exploration
Prototype
When the experience still needs hands-on iteration before delivery.
Read prototype →Existing install
Upgrade
0.3.0 / 0.4.0 → 0.5.0: init, then adoption or reseed.
Read upgrade →Watch the quick introduction video first. Start with vision if you are deciding whether to adopt. Start with upgrade if you already have 0.3.0 or 0.4.0 installed. Use the skills when you are doing the work with an agent.
