competing-hypothesis-generation

competing-hypothesis-generation is a skill for Claude Code, Codex from yogsoth-ai/de-anthropocentric-research-engine. It costs 20 tokens per session (424 once invoked), scanned A, original, Apache-2.0.

A procedure for generating multiple explanations of the same phenomenon that differ in their underlying cause or mechanism.

In plain words
What is it for?
It is for creating competing hypotheses before experiment design or further scientific reasoning.
Why use it?
It prevents researchers from testing only their first idea and makes alternative explanations explicit and distinct.

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

competing-hypothesis-generation 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.

What it actually says

Competing Hypothesis Generation

Generate genuinely distinct competing hypotheses for the same phenomenon to guard against confirmation bias and keep explanations open.

HARD-GATE

Not satisfied → stop and return error: primary hypothesis and phenomenon description required.

Pipeline

  1. Precondition check: verify completeness of the primary hypothesis and phenomenon description
  2. Alternative mechanism search: look for different causal mechanisms that can explain the same phenomenon
  3. Alternative theory application: derive predictions about the same phenomenon from different theoretical frameworks
  4. Reverse reasoning: consider explanations with the opposite causal direction
  5. Deduplication: ensure each competing hypothesis is mechanistically distinct from the primary hypothesis and from the other competing hypotheses
  6. Output competing hypothesis list

Output Format

[
  {
    "hypothesis_id": "CH1",
    "statement": "Competing hypothesis statement",
    "mechanism": "Different causal mechanism from the primary hypothesis",
    "theoretical_basis": "Theory or reasoning supporting this alternative",
    "key_difference": "How this differs mechanistically from the primary hypothesis",
    "shared_prediction": "Prediction shared with primary hypothesis (makes discrimination hard)",
    "unique_prediction": "Prediction unique to this hypothesis (enables discrimination)"
  }
]

At least 2 competing hypotheses, each mechanistically distinct from the primary hypothesis.

Changes

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.
