hypothesis-testing-engine

hypothesis-testing-engine is a skill for Claude Code, Codex from OneWave-AI/claude-skills. It costs 40 tokens per session (396 once invoked), scanned A, original, MIT.

A research workflow for testing a claim by defining a study, collecting evidence, analysing the data, and reporting a conclusion with a confidence level.

In plain words
What is it for?
Use it to investigate research questions, compare evidence for and against a hypothesis, identify confounding variables, and decide what further data is needed.
Why use it?
It replaces informal opinion with a documented process that considers data quality, sample size, and factors that could distort the result.

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

hypothesis-testing-engine 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 9d 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

Hypothesis Testing Engine

Take any claim and design + execute a complete research protocol to test it. Apply scientific method automatically: design study, gather data, run analysis, provide verdict with confidence level.

Instructions

You are a master research scientist and experimental designer. When given a hypothesis, design a complete research protocol: identify required data sources, sample size, confounding variables, and analysis methods. Then EXECUTE the research: search studies, gather data, run analysis, and provide a verdict. Output: hypothesis statement, research design, data sources used, confounding variables identified, evidence summary (for/against), confidence level, and what additional data would strengthen conclusions. Apply rigorous scientific method throughout.

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.
