What it does
Data Analysis is an agent skill from brycewang-stanford/Auto-Empirical-Research-Skills. End-to-end R data analysis for the sewage project. Writes analysis scripts following project conventions (here::here, arrow/parquet, fixest, modelsummary, native pipe), runs code review, and produces publication-ready tables and figures. This skill should be used when asked to "run an analysis", "estimate the model", "add a specification", or "write an R script".
Its SKILL.md is about 1.2k 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 Data & Analytics, covering Data analysis, DataFrames and Code review. 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
- Tasks that involve Data analysis
- Tasks that involve DataFrames
- Tasks that involve Code review
Example prompts
- “run an analysis”
- “estimate the model”
- “add a specification”
- “/data-analysis”
Requirements
- Pre-approved tools (allowed-tools): Read, Grep, Glob, Write, Edit, Bash, Agent
Workflow steps
5 steps, taken from the step headings in SKILL.md.
- Context Gathering
- Write Analysis Script
- Code Review
- Run the Script
- Present Results
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 these tools, so the agent can use them without asking each time:
ReadGrepGlobWriteEditBashAgent
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 r and bash).
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
Data Analysis loads about 1.2k tokens when it runs. Until then it costs about 95 tokens; SKILL.md has 357 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: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
allowed-tools: Read, Grep, Glob, Write, Edit, Bash, Agent
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 357 words (~1,189 tokens).
“Run an end-to-end data analysis following sewage project conventions.”

- data-analysis
- allowed-tools
- Read, Grep, Glob, Write, Edit, Bash, Agent

When should I use Data Analysis?
Data Analysis fits situations like: tasks that involve Data analysis; tasks that involve DataFrames; tasks that involve Code review.
How do I install Data Analysis in Claude Code?
Run `npx skills add brycewang-stanford/Auto-Empirical-Research-Skills --skill data-analysis -a claude-code`. Or copy the skill folder (skills/41-sticerd-eee-sewage-econometrics-check/skills/data-analysis in brycewang-stanford/Auto-Empirical-Research-Skills) into .claude/skills/data-analysis in your project. Claude Code loads it when a task matches its description.
How do I install Data Analysis in Codex?

Or copy the skill folder (skills/41-sticerd-eee-sewage-econometrics-check/skills/data-analysis in brycewang-stanford/Auto-Empirical-Research-Skills) into .agents/skills/data-analysis in your project. Codex loads it when a task matches its description.
Can I use Data Analysis in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add brycewang-stanford/Auto-Empirical-Research-Skills --skill data-analysis -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/data-analysis, .gemini/skills/data-analysis, .github/skills/data-analysis and .opencode/skills/data-analysis in your project.
What does Data Analysis need to run?
SKILL.md names no scripts, command-line tools or credentials: Data Analysis is instructions for the agent only. Its frontmatter pre-approves these tools: Read, Grep, Glob, Write, Edit, Bash, Agent.
Does Data Analysis 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 Data Analysis safe to install?
Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
What licence does Data Analysis use?
Data Analysis 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 Data Analysis use?
About 1.2k tokens (SKILL.md is roughly 4.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Data Analysis?
Skills that share tags, products or a category with Data Analysis: Python Executor (cortega26/chile-hub, 113 stars), Billing Review (polarsource/polar, 10k stars), Pandas Pro (Jeffallan/claude-skills, 12k stars) and Verified Data Analysis with pandas (pipeshub-ai/pipeshub-ai, 3.8k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
