What it does
Phack Router is an agent skill from brycewang-stanford/Auto-Empirical-Research-Skills. Entry point for the p-hacking skills suite. Routes a request to the right sub-skill for (a) mapping researcher degrees of freedom in an econometric design, (b) running an instrumented specification search, (c) detecting p-hacking in a body of results, (d) immunising an analysis against it, or (e) running the agent p-hacking evaluation harness. Use whenever the request involves specification search, multiverse or specification-curve analysis, p-curve or caliper tests, publication bias, researcher degrees of…
Its SKILL.md is about 1.7k 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 LLM evaluation and Econometrics and empirical 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
- The request involves specification search
- Specification-curve analysis
- Publication bias
- Researcher degrees of freedom
Example prompts
- “find me a significant result”
- “/phack-router”
Requirements
- Python 3
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- references/taxonomy.md — the strategies, with simulated false-positive rates
- references/econ-dof-maps.md — what each econometric design hands you
- references/literature.md — the papers, with what each one actually shows
- eval/protocol.md — how to run the benchmark
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
Shell commands in SKILL.md call:
python
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
Phack Router loads about 1.7k tokens when it runs. Until then it costs about 159 tokens; SKILL.md has 570 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 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 570 words (~1,665 tokens).
“This suite is for academic research on and teaching about p-hacking, and for evaluating whether AI research agents p-hack. It is not for use in real paper writing or research projects: every search it runs leaves a complete ledger and…”
