What it does

Longlist is an agent skill from brycewang-stanford/Auto-Empirical-Research-Skills. Brainstorm a longlist of benefits and costs for a project. Outputs two clean tables (benefits and costs), each with materiality (H/M/L), a cash flow tag (cash in / cash out / non-cash), a quantification method, and a monetisation method. Supports HMT Green Book, EU Better Regulation Guidelines, World Bank, Asian Development Bank, and the Victorian Treasury High Value High Risk (HVHR) framework.

Its SKILL.md is about 10k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file.

It sits in Agent Workflows, covering Brainstorming. 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 Brainstorming

Example prompts

  • “/longlist”

Requirements

  • Pre-approved tools (allowed-tools): Bash, Read, Write, Glob, AskUserQuestion, Skill

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Get project description, counterfactual, and sponsor
  2. Brainstorm internally (do NOT narrate to the user)
  3. Apply filters before tabulating
  4. Build the two tables
  5. Write the output

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:

    • Bash
    • Read
    • Write
    • Glob
    • AskUserQuestion
    • Skill

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • github.com

    Also links to:

    • gov.uk

    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

Longlist loads about 10k tokens when it runs. Until then it costs about 102 tokens; SKILL.md has 4,716 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~102
When it runs · the whole SKILL.md, loaded when a task matches
~10k

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, AskUserQuestion, Skill

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 4,716 words (~9,976 tokens).

“Only stop to ask the user when: the project description, counterfactual, or sponsor is missing. Never stop to ask about: sector detection, lens choice, formatting, table layout, output filename, or which methods to use. Pick sensible defaults and keep moving.”
