DocLayer

DocLayer is a zero-dependency engineering contract layer and safety harness for AI coding agents. When autonomous agents encounter errors, code alone doesn't convey operational prohibitions. DocLayer introduces: • doclayer explain: Inspect declared contracts and negative invariants before writing code. • doclayer check: Machine-check AST contract drift in CI. • 4-tier epistemic model: Separate facts from decisions. • Self-verifying: Governs its own Python codebase with zero dependencies.
