multi-llm-convergence

multi-llm-convergence is a plugin for Claude Code from donnfelker/loop-skills. Its manifest loads nothing; the 1 skill it bundles cost 192 tokens per session together, scanned A, original, MIT.

A plugin that sends plans, design documents, specifications, and code changes through alternating Codex and Claude reviews until both agree they meet the required standard.

In plain words
What is it for?
Use it for repeated cross-model review of an implementation diff or other project artifact when you want an auditable path to agreement.
Why use it?
Different model families can spot different problems, while per-round commits and local source references make the review progress traceable and keep reviewers grounded.

Security

Grade A, and why

multi-llm-convergence 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 4d 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

{
  "name": "multi-llm-convergence",
  "description": "Drives any artifact — a plan, PRD, design doc, spec, or implementation diff — to convergence by alternating two genuinely different LLM reviewers (a Codex reviewer and an independent Claude review subagent), applying each round's findings and looping until both independently agree the artifact clears the bar (default: no critical/high findings). Grounds offline reviewers in local source-of-truth clones so they don't stall, runs a liveness watchdog so a silent reviewer can't hang the loop, and commits per round for an auditable convergence trail.",

What it installs

The manifest is a name and a version. 1 skill travel with it, and installing the plugin installs all of them — 192 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.
