What it does
Hypothesis Generation is an agent skill from jimmc414/Kosmos. Generate testable hypotheses from observations. Use for formulating research questions, designing experiments, exploring competing explanations, developing predictions, and proposing mechanisms. Triggers: generate hypothesis, formulate hypothesis, research question, experimental design, competing explanations, mechanistic hypothesis, testable predictions, scientific inquiry.
Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files and assets (for example `assets/hypothesis_output_template.md`, `references/experimental_design_patterns.md` and `references/hypothesis_quality_criteria.md`).
It sits in Research & Science, covering Hypothesis generation. The repository describes itself as: Kosmos: An AI Scientist for Autonomous Discovery - An implementation and adaptation to be driven by Claude Code or API - Based on the Kosmos AI Paper -….
When your agent uses it

- Exploring competing explanations
- Developing predictions
Example prompts
- “/hypothesis-generation”
Workflow steps
8 steps, taken from the step headings in SKILL.md.
- Understand the Phenomenon
- Conduct Comprehensive Literature Search
- Synthesize Existing Evidence
- Generate Competing Hypotheses
- Evaluate Hypothesis Quality
- Design Experimental Tests
- Formulate Testable Predictions
- Present Structured Output
What it can do on your machine
Read from SKILL.md and the folder at commit 73f4d2a. 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.
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 Generation loads about 1.7k tokens when it runs, and up to ~8.7k if it reads all its reference files. Until then it costs about 100 tokens; SKILL.md has 741 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 741 words (~1,735 tokens).
“Hypothesis generation is a systematic process for developing testable explanations. Formulate evidence-based hypotheses from observations, design experiments, explore competing explanations, and develop predictions. Apply this skill for scientific inquiry across domains.”
