llm-council

llm-council is a skill for Claude Code, Codex from refaelach/gmba-class-19-skills. It costs 218 tokens per session (3,857 once invoked), scanned A, a copy of llm-council-v2, MIT.

A review process that asks five AI advisors to analyze a question independently, review one another anonymously, and combine their findings into a final answer.

In plain words
What is it for?
Use it to pressure-test plans, evaluate choices, explore ideas, and produce a report with the reasoning behind the conclusion.
Why use it?
It reduces the risk of relying on one unchecked AI response when comparing ideas or making decisions.

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.

Security

Grade A, and why

llm-council 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 11d 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.

Compatibility

The skill follows the open Agent Skills standard, so it loads natively in Claude Code, Codex, Gemini CLI, Cursor, and any other tool that supports the spec. The full experience differs based on which features the tool exposes:

  • Full experience (Claude Code, Codex): Spawns 5 advisors and 5 reviewers as parallel sub-agents, generates an HTML report and saved transcript using filesystem tools.
  • Strong experience (Cursor, Gemini CLI, Antigravity): Sub-agent support varies; advisors may run sequentially. File outputs work where the tool has filesystem access.
  • Partial experience (ChatGPT Custom GPTs, Gemini Gems, prompt-only setups): The methodology works the same, but advisors run sequentially in one chat. The HTML report step is skipped (or output as a single Markdown document instead). Paste the body of this SKILL.md into a Custom GPT, Gem, or system prompt, then ask your question with one of the trigger phrases.

The core insight (5 thinking styles + anonymous peer review + chairman synthesis) is what matters, and that pattern is portable. The parallelism and file outputs are nice-to-haves.


You ask one AI a question, you get one answer. That answer might be great. It might be mid. You have no way to tell because you only saw one perspective.

The council fixes this. It runs your question through 5 independent advisors, each thinking from a fundamentally different angle. Then they review each other's work. Then a chairman synthesizes everything into a final recommendation that tells you where the advisors agree, where they clash, and what you should actually do.

This is adapted from Andrej Karpathy's LLM Council. He dispatches queries to multiple models, has them peer-review each other anonymously, then a chairman produces the final answer. We do the same thing inside Claude using sub-agents with different thinking lenses instead of different models.


when to run the council

The council is for questions where being wrong is expensive.

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.
