# CCDD — Context Contract-Driven Development

> Methodology for reliable AI agents: the LLM's context (prompts, policies)
> becomes a versioned, signed, gate-enforced CONTRACT (context.yaml). L1 lint,
> L2 deterministic regression gate (R1-R9), L3 runtime assembly + guardrails.
> This page publishes the methodology's own docs as searchable skills.
