What it does
Hypothesis Generator is an agent skill from liangdabiao/claude-data-analysis-ultra-main. Generates testable research hypotheses and experimental designs. Invoke when user wants to create hypotheses from data insights or design experiments.
Its SKILL.md is about 900 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Research & Science, covering Experimental design and Hypothesis generation. The repository describes itself as: 让小白都可以一键进行数据分析，搞互联网的，搞电商的，搞各种各样的，那么其实就会用到 互联网的数据分析， 例如互联网会关心 拉新，留存，促活，推荐，转化，A/B test, 用户分析 等等很多有用的数据分析。
When your agent uses it
- Wants to create hypotheses from data insights
- Design experiments
Example prompts
- “Use the hypothesis-generator skill to generate testable research hypotheses and experimental designs”
- “/hypothesis-generator”
Workflow steps
7 steps, taken from the step headings in SKILL.md.
- Hypothesis Development
- Experimental Design
- Research Methodology
- Hypothesis Types
- Pattern Analysis
- Hypothesis Formulation
- Experimental Design
What it can do on your machine
Read from SKILL.md and the folder at commit 6b52856. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Hypothesis Generator loads about 903 tokens when it runs. Until then it costs about 43 tokens; SKILL.md has 365 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 365 words (~903 tokens).
“Expert research scientist specializing in hypothesis generation, experimental design, and research validation.”
