What is martinloop-govern?

A workflow for controlling coding-agent implementation with MartinLoop, including planning, limits, preflight checks, recovery, and evidence from verifiers. It treats a verified result, a stop, and unresolved review as different outcomes.

Use it to check the environment, estimate and plan work, validate the execution contract, run the bounded task, and inspect the final evidence dossier or handoff.

It prevents an agent from being treated as successful without evidence and keeps the requested work within an agreed scope and budget.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add Keesan12/martin-loop --skill martinloop-govern

Clone the repo

git clone --depth 1 https://github.com/Keesan12/martin-loop

Made for: Claude Code, Codex.

Or install martinloop, the plugin that ships this one along with the rest of its 1 skill, 1 MCP server.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00029	$0.00298
Opus 5.5	$0.00012	$0.00119
Sonnet 5.5	$0.00006	$0.00060
Haiku 4.5	$0.00003	$0.00030

Security

Grade A, and why

martinloop-govern scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Govern With MartinLoop

Use MartinLoop as the execution-control and evidence layer around the coding agent. Preserve the user's requested scope and never replace verifier evidence with an agent assertion.

Workflow

Call martin_doctor to confirm the environment is ready.
Call martin_estimate to expose budget and cost posture before spend.
Call martin_plan to define the bounded objective, files, and verification.
Call martin_preflight and resolve blocking contract issues before execution.
Call martin_run only after preflight accepts the contract.
Call martin_dossier after the run and inspect its evidence.

Outcome Rules

Report VERIFIED only with verifier-backed completion evidence.
Treat STOPPED as a real enforced boundary and report its recorded reason.
Treat NEEDS_REVIEW as unresolved evidence, never successful completion.
Preserve the dossier or Verified Handoff as the completion record.
Never weaken a gate, increase a budget, or approve protected work without authorization.
Let the coding agent or provider select its model unless the user explicitly overrides it.

First Task

For a low-risk trial, govern a small repository change with a real verifier and inspect the resulting dossier.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

martinloop-govern is a skill published in the GitHub repository Keesan12/martin-loop (394 stars, last pushed today), licensed Apache-2.0. It adds 29 tokens to every session and 298 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
