martin-loop vs agent-governance-toolkit

martin-loop: MartinLoop is a governance layer for AI coding loops that enforces budget caps, verifier gates, rollback evidence, and audit trails. It prevents unbounded retries by stopping unsafe or uneconomical work before execution, providing visibility and accountability for autonomous coding agents.; agent-governance-toolkit: Agent Governance Toolkit intercepts every tool call, message and delegation in deterministic application code before it runs, so denied actions cannot happen regardless of the prompt. It adds agent identity, sandboxing, tamper-evident audit records and SRE tooling, with SDKs for Python, TypeScript and other languages.
