What it does
Phack Detection is an agent skill from brycewang-stanford/Auto-Empirical-Research-Skills. Test whether a body of reported results shows p-hacking, selective reporting or selection between stages, using the p-curve battery and the threshold and across-stages tests of Adda, Decker and Ottaviani (2020). Implements the binomial, Fisher, Stouffer and least-concave-majorant monotonicity tests of Elliott, Kudrin and Wuethrich (2022); threshold-bunching tests calibrated against a smooth counterfactual density; a Cattaneo-Jansson-Ma density-jump test and a right-side spike test that tell a level shift (results…
Its SKILL.md is about 2.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

When your agent uses it
- Asked whether a literature
- A research design
- A set of agent runs shows evidence of p-hacking
- Publication bias
Example prompts
- “/phack-detection”
Requirements
- Python 3
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 Detection loads about 2.4k tokens when it runs. Until then it costs about 223 tokens; SKILL.md has 1,235 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 1,235 words (~2,408 tokens).
“Every test here is a test on the distribution across many results. None of them can establish that any individual paper was p-hacked, and the report says so on every run. Treat a flag as a reason to look, never…”

When should I use Phack Detection?
Phack Detection fits situations like: asked whether a literature; A research design; A set of agent runs shows evidence of p-hacking; publication bias.
How do I install Phack Detection in Claude Code?
Run `npx skills add brycewang-stanford/Auto-Empirical-Research-Skills --skill phack-detection -a claude-code`. Or copy the skill folder (skills/73-brycewang-p-hacking-skills/skills/06-phack-detection in brycewang-stanford/Auto-Empirical-Research-Skills) into .claude/skills/phack-detection in your project. Claude Code loads it when a task matches its description.
How do I install Phack Detection in Codex?
Run `npx skills add brycewang-stanford/Auto-Empirical-Research-Skills --skill phack-detection -a codex`. Or copy the skill folder (skills/73-brycewang-p-hacking-skills/skills/06-phack-detection in brycewang-stanford/Auto-Empirical-Research-Skills) into .agents/skills/phack-detection in your project.
