name	loop-verifier
description	The independent gate for your agent loop or swarm. Use when you run an autonomous or scheduled agent loop OR a cheap-volume / open-weight / open-source agent swarm (Claude Code /loop, scheduled tasks, hooks, Codex Automations, CI-triggered agents, cron'd agents, open-source agent frameworks like CrewAI / LangGraph / AutoGen, hundreds of parallel sub-agents) and need an objective verifier that is NOT the agent that did the work — before the loop merges, deploys, trades, pays, publishes, or SAVES A RESULT AS A REUSABLE SKILL. Turns an independent judgment verdict into an exit code your loop can gate on, plus a portable signed proof attached to whatever the loop ships or saves — so a confident-but-wrong output never gets kept as a skill and replayed forever. The engine can be the cheapest model you like; the gate has to be one that isn't the engine.

Loop verifier — the gate that isn't the maker

An agent loop runs while nobody watches. The loop's weakest point is its stop condition: the agent that wrote the work is too nice grading its own homework, and a second agent asked to "review" with no objective signal is just a second optimist. Tests catch what tests cover. The judgment calls — is this change sound? is this trade sane at this capital scale? should this ship? — need a verifier that is not the maker and not the maker's twin.

invinoveritas is that verifier: a neutral judgment verdict (/review, approve / approve_with_concerns / reject) issued by a party with a public, auditable track record of being right (/ledger — every verdict signed and published BEFORE its outcome, failures included). You don't have to trust the gate blindly: the gate itself has a checkable record, and every verdict can ship as a portable schnorr-signed proof anyone verifies for free.

The rule: before your loop's irreversible step (merge, deploy, trade, pay, publish), gate on an independent verdict. Attach the signed proof to whatever the loop ships.

Triggers

• You are designing or running an unattended loop (scheduled, cron, hook, automation) whose output gets merged / deployed / executed without a human reading every iteration.
• Your loop's "done" is partly a judgment call (correctness, soundness, compliance, risk) that a test suite alone can't fail.
• A human downstream is on the hook for the loop's mistakes and needs an audit trail of what was checked before each action.
• You run a cheap-volume, open-weight, or open-source agent swarm (hundreds of parallel sub-agents, or an open-source framework like CrewAI / LangGraph / AutoGen) whose outputs get merged, acted on, or saved as reusable skills — and need an independent gate so a confident-but-wrong result isn't kept and replayed forever. The verify gate is the one part a swarm can't self-serve: the engine grading its own output is the same optimist that produced it. Run the cheapest engine you like; keep a gate that isn't the engine.
