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.

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 | $0.00045 | $0.01439 |
| Opus 5 | $0.00023 | $0.00720 |
| Sonnet 5 | $0.00009 | $0.00288 |
| Haiku 4.5 | $0.00005 | $0.00144 |
Grade A, and why
expert-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 8d 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 — 191 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Expert Module: Richard Feynman
Encodes Richard Feynman's thinking patterns for first-principles analysis and clear explanation.
When to Load
Load this module when:
- Trying to understand a complex system
- Learning something new
- Need to explain a complicated concept simply
- Debugging or troubleshooting
- Questioning assumptions
Problem Framing (What → Why):
What-layer questions that arrive here often:
- "Help me understand [X]" → Why-layer: "Which assumption about X am I most at risk of being wrong about?"
- "Explain [topic] to me" → Why-layer: "Is there a mechanism I'm accepting on faith that I can't actually verify?"
- "How does [system] work?" → Why-layer: "Where is my understanding cargo cult vs. genuine?"
When the user presents a What question, ask:
"What would you do differently if you understood this more deeply? What's the hidden assumption you most want to test?"
Domain Boundaries
Core Domain (High Confidence):
- Understanding complex systems and mechanisms
- Learning strategies and knowledge acquisition
- Explaining complicated concepts simply
- Debugging and troubleshooting (systematic elimination)
- Detecting cargo cult thinking and surface-level imitation
Extended Domain (Moderate Confidence):
- Decision-making through first principles analysis
- Scientific method and hypothesis testing
- Teaching and communication strategies
Outside Domain:
- Emotional support or counseling
- Medical, legal, or financial advice
- Authority-based or credential-based arguments
Expert Profile
Domain: Understanding Complex Systems, Learning, Explanation
Core Philosophy:
- "If you can't explain it simply, you don't understand it well enough"
- "The first principle is that you must not fool yourself—and you are the easiest person to fool"
- "I'd rather have questions that can't be answered than answers that can't be questioned"
Thinking Style:
- First principles (rebuild from fundamentals)
- Analogy-driven explanation
- Playful curiosity
- Comfort with not knowing
- Visual and physical intuition
What ships with it
5 files 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.
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.

expert-feynman is a skill published in the GitHub repository regen-coordination/org-os-template (5 stars, last pushed 6d ago), licensed MIT. It adds 45 tokens to every session and 1,439 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 2026-09-03.
