steeropathy: Skill for Claude Code

.claude/skills/new-experiment/SKILL.md

new-experiment is a skill for Claude Code from moudrkat/steeropathy. It costs 105 tokens per session (2,022 once invoked), scanned A, original, MIT.

Instructions for creating experiments in steeropathy, a research project where agents communicate through internal model signals instead of written messages. They explain the project’s existing experiments and how to build a new reproducible probe.

In plain words
What is it for?
Use them to design or add a new experiment, game, or probe involving model activations or J-space, the internal word-like states that do not become output tokens.
Why use it?
They help an agent fit a new experiment into the project’s structure and test its results honestly, including failures and controls.

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

new-experiment 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.

Build a new steeropathy experiment

steeropathy is a lab for agents that talk through model internals, never text: one agent's state is read off its activations (or its J-space — the words forming in its layers that never become tokens) and either measured or pushed into another agent's forward pass. Every experiment is a probe, not a product — the goal is a reproducible existence-proof you can play with, run honestly with controls, and write up including the failures.

Read the closest existing bench before writing a new one — they are short and each is a set of answers to the same four questions:

  • steeropathy/transmit.py — the thesis in ~15 lines: read a mood off one agent, push it into another. The direction/injection/before-after core.
  • steeropathy/ecosystem.pyEco: a population, per-round step(), the post/get/_state_of plumbing everything else subclasses.
  • steeropathy/resonance.pyReso(Eco): ledgers, transfer/conservation, the J-space channel, an unsteered decision turn.
  • steeropathy/unsaid.pyUnsaid: the pure J-space channel (_flicker), no steering at all — only reading.
  • steeropathy/warmer.py, steeropathy/zombie.py — a hot-and-cold game and a refusal-outbreak game built on the above.

The four choices that define an experiment

  1. Whose internals you read — one agent, a pair, a room of N.
  2. What crosses — a mood/concept vector, a scalar on one axis, the J-space word cloud, a similarity, or nothing (read-only).
  3. Who decides — nobody (mechanical rules), or agents choosing via an unsteered tool call (steering breaks JSON long before prose).
  4. What you measure — and against what control.

The plumbing to reuse (don't reinvent)

  • Subclass Eco (or Unsaid) for self.post(path, body) / self.get(path) against brainscope. Write a custom __init__ (like Reso) — don't call super().__init__ if you don't want its mood seed.
  • Build a direction from the model's own contrast, not a baked vector: capture_mood(url, texts) returns mean(texts) − neutral, unit-normed, at a good layer. For a custom axis, mean-pool /capture over two prompt sets and subtract. Register it with POST /directions {name, vector} and steer with {"name", "strength", "layer_from", "layer_to"} in the chat body.
  • Read J-space from the generation's trace: tag each call with metadata:{demo, case, variant}, then match it in GET /traces, fetch GET /traces/{id}, and walk trace["jlens"] for {t, p} tokens. Filter with a dictionary + stopwords (see unsaid.STOP/WORDS), or a task lexicon (see zombie.REFUSE_WORDS).
  • Enable the J-space channel once with POST /jlens {"on": true}; if it fails, the server has no lens — degrade, don't crash.

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.

new-experiment is a skill published in the GitHub repository moudrkat/steeropathy (22 stars, last pushed 3d ago), licensed MIT. It adds 105 tokens to every session and 2,022 once invoked, about $0.0005 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.
