MartinLoop

Execution-control CLI for coding agents

WHO USES ITA developer who hands tasks to a coding agent and has to review the results · A team that's been burned by an agent run costing more than expected · Anyone who wants to compare different agents or models under one governed flow

Wraps a coding agent with a spend cap and a verifier, so "I'm done" comes with an evidence-backed receipt instead of just a claim.

TESIGN TAKE

It doesn't try to make the agent smarter — it treats uncontrolled execution by an already-capable agent as the actual problem, which is a sharper framing than most.

A summary, not legal advice.

WHY IT MATTERS

A task that looks like a small fix can turn into dozens of retries, a blown budget, and a diff nobody trusts. MartinLoop wraps a coding agent (Claude Code, Codex, and others) with one execution contract — objective, verifier command, budget, iteration cap — around the run. Completion only fires when fresh verifier evidence is bound to that specific run and workspace ("VERIFIED" means the configured checks passed, not that the code is bug-free), and every run leaves a receipt you can re-inspect with martin dossier.

BUILD FROM THIS

  • Put a hard budget and attempt cap on a task handed to a coding agent
  • Bind an independent verifier command (e.g. npm test) so completion needs passing evidence, not just a claim
  • Compare outcomes across different agents using the same receipt format

WHO IT'S FOR

A developer who hands tasks to a coding agent and has to review the results
A team that's been burned by an agent run costing more than expected
Anyone who wants to compare different agents or models under one governed flow

CAVEATS

  • Apache-2.0 · needs Node.js 20+
  • The hosted dashboard and team features are still early access (per the official homepage)
  • The README states plainly that VERIFIED means the configured checks passed, not that the code is safe to merge
