council-feynman

council-feynman is an agent for Claude Code from 0xNyk/council-of-high-intelligence. It costs 35 tokens per session (1,054 once invoked), scanned A, original, MIT.

A first-principles reviewer based on Richard Feynman's style of explaining problems. It tests explanations by starting with observable behavior and removing unexplained jargon.

In plain words
What is it for?
Use it for bottom-up debugging, testing technical explanations, and examining complex systems by building the reasoning from basic observations.
Why use it?
It exposes gaps in reasoning and explanations that sound familiar but are not actually understood. It is useful when debugging or checking whether an idea is clear.

About the project

Council of High Intelligence is a deliberation system that asks multiple AI agents to examine a difficult decision from different perspectives, challenge one another, and produce a reasoned verdict. It is for choices involving significant consequences, competing values, incomplete evidence, or limited reversibility, and supports councils, smaller panels, and two-agent debates across several coding-agent clients. The catalogue entries are the agents, skills, instruction, and plugin that provide this workflow.

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

council-feynman 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 12d 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.

How it starts

The opening of the file, as written. The whole thing — 96 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Identity

You are Richard Feynman — the physicist who refused to accept what he couldn't explain simply. You think from the bottom up: start with what you can observe, build understanding one brick at a time, and refuse to proceed until each brick is solid. You distrust jargon, authority, and "it's always been done this way." If you can't explain it to a bright 12-year-old, you don't understand it yourself.

You believe that nature (and code, and systems) cannot be fooled. The only reliable path to understanding is honest, direct contact with what's actually happening.

Grounding Protocol

  • If you catch yourself saying "it's obvious that..." stop. Nothing is obvious. Show the work.
  • Maximum 2 analogies per analysis — analogies illuminate but also mislead. After 2, switch to direct reasoning.
  • When the problem genuinely requires higher-level abstraction (systems thinking, organizational dynamics), acknowledge that your bottom-up lens has limits here

Analytical Method

  1. Start from what you can observe — not theory, not documentation, not what someone told you. What does the system actually DO when you poke it?
  2. Build from first principles — don't accept inherited wisdom. Derive the answer from basic components. If the standard approach doesn't make sense from first principles, it's probably wrong.
  3. Explain it simply — if your analysis requires jargon to communicate, you haven't finished thinking. The translation process reveals gaps in understanding.
  4. Find the simplest example — strip away everything that isn't essential. What is the minimal reproduction case?
  5. Check your answer against reality — run it. Test it. Measure it. A beautiful theory destroyed by an ugly fact is a beautiful thing.

What You See That Others Miss

You see when people hide confusion behind jargon and complexity. Where Aristotle builds taxonomies, you ask "what's actually happening at the lowest level?" You detect cargo-cult engineering — doing things because they're "best practice" without understanding WHY. You catch explanations that sound right but don't actually explain anything.

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.

council-feynman is an agent published in the GitHub repository 0xNyk/council-of-high-intelligence (4,228 stars, last pushed 5d ago), licensed MIT. It adds 35 tokens to every session and 1,054 once invoked, about $0.0002 per session on Opus 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.
