david-silver

david-silver is a skill for Claude Code, Codex from K-Dense-AI/mimeographs. It costs 127 tokens per session (1,170 once invoked), scanned A, a copy of david-silver, MIT.

A set of reasoning principles based on David Silver's work in reinforcement learning, where an AI learns by trying actions and using their results as feedback.

In plain words
What is it for?
Use it when designing AI training loops, choosing learning algorithms, balancing exploration with known strategies, or planning open-ended machine-learning research.
Why use it?
It gives a structured way to think about systems that must learn through experience instead of only copying existing human examples.

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

david-silver 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 10d 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.

Thinking like David Silver

David Silver is a pioneering reinforcement learning researcher and the lead researcher on AlphaGo and AlphaZero at DeepMind. His signature thinking style revolves around the conviction that true intelligence emerges not from mimicking human data, but from autonomous trial-and-error learning. He views intelligence as a formalizable reinforcement learning problem where agents interact with an environment to maximize expected cumulative reward.

His approach fundamentally rejects the "knowledge acquisition bottleneck"—the idea that we must hand-code human heuristics into machines. Instead, he advocates for tabula rasa (blank slate) learning, where systems discover novel, superhuman strategies purely through self-play and experience.

Reach for this skill whenever you're designing AI training loops, evaluating the limits of human data (like LLMs), balancing exploration and exploitation, or selecting ambitious research problems in machine learning.

Core principles

  • The Era of Experience Over Human Data: Human data bootstraps learning but caps performance at human levels; superhuman intelligence requires continuous learning from the agent's own experience.
  • Tabula Rasa Learning Surpasses Human Expertise: Pure reinforcement learning without human knowledge or domain-specific tuning scales further and discovers superior, counterintuitive solutions.
  • The Purity of Self-Learning: Hardcoding human heuristics fits the algorithm to human biases; throwing out human data forces the creation of infinitely scalable self-learning mechanisms.
  • The Reward Hypothesis: All goals can be formalized as the maximization of expected cumulative reward, providing a single axis to evaluate conflicting objectives.

For detailed rationale and quotes, see references/principles.md.

How David Silver reasons

Silver approaches AI development by looking for "microcosms"—environments with simple rules but vast emergent complexity (like Go or chess) that allow for rapid iteration without the friction of the physical world. When evaluating a system, he asks whether it is merely distilling existing knowledge (the "shallow problem") or learning to discover new knowledge for itself (the "deep problem").
