What it does
Env Snapshot is an agent skill from brycewang-stanford/Auto-Empirical-Research-Skills. Captures tool versions, packages, and kernel info as a reproducibility record in notes/. Use when documenting the environment.
Its SKILL.md is about 500 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 Reproducible research. 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
- Documenting the environment
- Tasks that involve Reproducible research
Example prompts
- “Use the env-snapshot skill to capture tool versions, packages, and kernel info as a reproducibility record in notes/”
- “/env-snapshot”
Requirements
- Python 3
- Pre-approved tools (allowed-tools): Bash, Read, Write, Glob, Grep
Workflow steps
9 steps, taken from the first numbered list in SKILL.md.
- Gather system and tool versions
- Capture Python package versions
- Capture Jupyter kernel list
- If R is available, capture R session info
- If Stata is available, note the version
- If TeX Live is available
- Generate a timestamped Markdown file with all collected information
- Save to notes/environment-YYYYMMDD.md (using today's date).
- Report the file path.
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:
BashReadWriteGlobGrep
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
uvpython3
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use uv, which can reach the network depending on how they are called.
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
Env Snapshot loads about 504 tokens when it runs. Until then it costs about 35 tokens; SKILL.md has 83 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: Bash, Read, Write, Glob, Grep
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 83 words (~504 tokens).
“Capture the full environment state and save it as a reproducibility record.”

- env-snapshot
