MartinLoop is an open-source governance and orchestration harness designed to manage autonomous AI coding workflows. Rather than acting as a standalone AI coding agent or IDE, it wraps existing agents and models with runtime guardrails, strict budget limits, automated verification gates, and auditable run receipts. In daily operations, developers execute runs through a terminal CLI command (such as `martin run`) or integrate it into IDEs and CI/CD pipelines. Users define tasks, timeboxes, strict spend caps, and verification commands (for example, pointing to a test runner like `pnpm test`). MartinLoop then orchestrates the underlying model or agent—including Claude, Codex, Gemini, OpenHands, or open-source LLMs—evaluating policies, monitoring step-by-step actions, and recording failure taxonomies and telemetry in structured JSONL output. What distinguishes MartinLoop from typical agent frameworks is its explicit focus on cost governance and verifiable completion. Unbounded retry loops are halted when budget ceilings are reached or when repetitive failures occur. An agent cannot declare a task finished without satisfying an independent verifier gate and generating an immutable run receipt detailing commits, diffs, reversibility data, and exact spend. MartinLoop's core CLI and orchestration layer is licensed under the Apache License 2.0 and available at no cost via npm. Enterprise extensions such as MartinLoop360 and HeadlessOS offer additional features including OPA-backed policy-as-code evaluation, business context compilation, and team dashboards.

--budget 3). MartinLoop prevents the agent from entering infinite retry loops, halting execution immediately if the spend limit is reached and producing a detailed log of all attempted changes.--verify pnpm test). The agent is blocked from submitting pull requests or claiming closure unless the verification gate passes with clear exit codes and diff artifacts.MartinLoop is built for platform engineers, engineering leads, and developers running autonomous agent loops in terminal and CI environments who need to control API costs and verify agent output. It is less suited for individual developers looking for a simple autocomplete chat extension without autonomous execution or governance requirements.
bash npm install -g martin-loopANTHROPIC_API_KEY, OPENAI_API_KEY, or GEMINI_API_KEY) are exported in your terminal environment, then check the installation: bash martin --versionbash martin run "fix flaky CI" --budget 3 --verify "pnpm test" MartinLoop will initialize the run contract, execute the task against your configured model, validate the changes with your test runner, and output a JSONL run receipt detailing the final cost and exit status.Part of CLI Coding Agents
