Core mathematical concepts and theoretical frameworks for statistics

  • Works in 3 steps: Find any unbiased estimator $\hat{\theta}$ → Find complete sufficient statistic $T$ → Compute $E[\hat{\theta} \mid T]$
  • Tasks that involve Statistics
  • SKILL.md covers Sufficiency, Completeness, UMVUE and Rao-Blackwell and Exponential Families, plus 2 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Mathematical Foundations is an agent skill from brycewang-stanford/Auto-Empirical-Research-Skills. Core mathematical concepts and theoretical frameworks for statistics

Its SKILL.md is about 4.1k 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 Data & Analytics, covering Statistics. 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 Statistics

Example prompts

  • “/mathematical-foundations”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Find any unbiased estimator $\hat{\theta}$
  2. Find complete sufficient statistic $T$
  3. Compute $E[\hat{\theta} \mid T]$

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 r).

    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

Mathematical Foundations loads about 4.1k tokens when it runs. Until then it costs about 23 tokens; SKILL.md has 1,160 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~23
When it runs · the whole SKILL.md, loaded when a task matches
~4.1k

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 1,160 words (~4,074 tokens).

Codex loads it when a task matches its description.

Can I use Mathematical Foundations 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 mathematical-foundations -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/mathematical-foundations, .gemini/skills/mathematical-foundations, .github/skills/mathematical-foundations and .opencode/skills/mathematical-foundations in your project.

What does Mathematical Foundations need to run?

SKILL.md names no scripts, command-line tools or credentials: Mathematical Foundations is instructions for the agent only.

Does Mathematical Foundations 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 Mathematical Foundations 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.
