What it does
C1 is an agent skill from brycewang-stanford/Auto-Empirical-Research-Skills. VS-Enhanced Quantitative Design Consultant with Materials & Sampling Enhanced VS 3-Phase process: Avoids obvious experimental designs, proposes context-optimal quantitative strategies Absorbed C4 (Experimental Materials Developer) and D1 (Sampling Strategy Advisor) capabilities Use when: selecting quantitative research design, planning experimental/survey methodology, power analysis, developing materials, sampling Triggers: RCT, quasi-experimental, experimental design, survey design, power analysis, sample size…
Its SKILL.md is about 9.1k 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. The repository describes itself as: 🔬 A curated collection of 23,000+ agent skills for empirical research across 8 social science disciplines. | 精选 23,000+ AI Agent 技能库，覆盖8大社会科学学科的实证研究。CoPaper.AI…
When your agent uses it
- : selecting quantitative research design
- Planning experimental/survey methodology
- Developing materials
- Sampling Triggers: RCT
Example prompts
- “/c1”
Workflow steps
6 steps, taken from the step headings in SKILL.md.
- Modal Research Design Identification
- Alternative Design Options
- Recommendation Execution
- Experimental Designs (Random Assignment)
- Survey Designs
- Power Analysis
What it can do on your machine
Read from SKILL.md and the folder at commit 9fa87d8. 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 yaml and 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
C1 loads about 9.1k tokens when it runs. Until then it costs about 144 tokens; SKILL.md has 1,199 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
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,199 words (~9,056 tokens).
“Before proceeding with internal VS, check if VS Arena is enabled:”
- name
- c1
- version
- 12.0.1

What does C1 do?
VS-Enhanced Quantitative Design Consultant with Materials & Sampling Enhanced VS 3-Phase process: Avoids obvious experimental designs, proposes context-optimal quantitative strategies Absorbed C4…. C1 is an agent skill from brycewang-stanford/Auto-Empirical-Research-Skills.
When should I use C1?
C1 fits situations like: : selecting quantitative research design; planning experimental/survey methodology; developing materials; sampling Triggers: RCT.
How do I install C1 in Claude Code?
Run `npx skills add brycewang-stanford/Auto-Empirical-Research-Skills --skill c1 -a claude-code`. Or copy the skill folder (skills/25-HosungYou-Diverga/skills/c1 in brycewang-stanford/Auto-Empirical-Research-Skills) into .claude/skills/c1 in your project. Claude Code loads it when a task matches its description.
How do I install C1 in Codex?

To copy it by hand, put the folder in .cursor/skills/c1, .gemini/skills/c1, .github/skills/c1 and .opencode/skills/c1 in your project.
What does C1 need to run?
SKILL.md names no scripts, command-line tools or credentials: C1 is instructions for the agent only.
Does C1 access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is C1 safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does C1 use?
C1 has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
How many tokens does C1 use?
About 9.1k tokens (SKILL.md is roughly 36k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
