What it does

Identification Theory is an agent skill from brycewang-stanford/Auto-Empirical-Research-Skills. DAG and potential outcomes frameworks for causal mediation identification

Its SKILL.md is about 3.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `.backups/SKILL-2025-12-09T03-53-59-604Z.md`).

It sits in Legal & Compliance, covering Dispute resolution. 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 Dispute resolution

Example prompts

  • “/identification-theory”

Workflow steps

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

  1. Potential Outcomes (Rubin/Neyman)
  2. Structural Causal Models (Pearl)
  3. Average Treatment Effect (ATE)
  4. Average Treatment Effect on Treated (ATT)
  5. Natural Direct and Indirect Effects (Mediation)
  6. Controlled Direct Effect (CDE)
  7. Conditioning on Colliders
  8. Conditioning on Mediators
  9. Overcontrol Bias
  10. M-Bias
  11. Table 2 Fallacy

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 and latex).

    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

Identification Theory loads about 3.9k tokens when it runs. Until then it costs about 24 tokens; SKILL.md has 1,311 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~24
When it runs · the whole SKILL.md, loaded when a task matches
~3.9k

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 1,311 words (~3,927 tokens).
