Nomos
Nomos is a transactional Go runtime for coding agents and Git repositories that prevents shortcut failures.
Nomos sits between coding agents like Claude Code, Cursor, or Aider and your Git repository to prevent reward hacking, hollow stubs, and workspace drift. It enforces causal INT and SUB spec-versus-code DAGs, hermetic Git worktree sandboxes, and 42 polyglot anti-reward-hacking AST quality gates. The software uses receipt-gated SQLite memory and atomic Two-Phase Commit releases before any code touches main. It supports languages including Go, TypeScript, Svelte, Python, Rust, C, C++, Java, Kotlin, and CSharp. Developers initialize the repository with a single command to automatically scaffold configuration files, agent rules, and self-healing Git defense hooks.
