reproducible-science

Scaffold reproducible science workflows in one command.

Install

pip install reproducible-science

This installs repro and its three dependencies: prereg, citations, results-cli.

Quick start

repro init my_experiment

initializing my_experiment
  wrote my_experiment/my_experiment/PREREG.md
  wrote my_experiment/.results/ledger.jsonl
  wrote my_experiment/.citations/
  wrote my_experiment/CLAUDE.md

This creates:

my_experiment/
    PREREG.md           the plan (OSF headings)
    CLAUDE.md           tells Claude Code about the tools
    .results/           results ledger
    .citations/         citation library
    claims/             claim files for citation verification
    data/               raw data
    scripts/            analysis scripts
    figures/            output figures

Verify everything at once

cd my_experiment
repro verify

Reads repro.yaml and checks every declared evidence assertion against the artifact it names. It spawns nothing: prereg, results and citations are separate commands.

The workflow

prereg freeze                         # lock the plan
results seal PREREG.md analysis.py    # hash inputs
results access "read metadata" --level "metadata only"

# run the computation

results run output.json --run-id exp_001
results claim "ICC = 0.42" --run-id exp_001 --confirmatory --location "Table 2"
repro verify                          # check everything

What's included

Tool	CLI	PyPI	What it does
prereg	`prereg`	`prereg`	Freeze a plan before running, record what changed after
citations	`citations`	`citations`	Verify quotations resolve in pinned source artifacts
results	`results`	`results-cli`	Seal inputs, record outputs, bind claims to runs, verify the chain

Inside adduce

adduce scores a repository for reproducibility across categories. Installing the extra registers one rule with it, so a repository that declares a repro.yaml has its evidence assertions checked as part of adduce check:

pip install "reproducible-science[adduce]"
adduce check .

The rule reports an aggregate — every assertion holding is a pass, some holding is partial, a pinned artifact having changed is a failure naming it — and writes the full per-assertion report to .adduce/repro-report.json, since one finding cannot carry thousands of outcomes. A repository with no manifest is out of scope rather than failing, and a verifier that cannot run reports UNKNOWN: a missing toolchain is not the repository's fault.

adduce is not a dependency of this package, and this package is not a dependency of adduce.

Claude Code

This repo is also a Claude Code plugin marketplace bundling all three tools:

/plugin marketplace add elliottower/reproducible-science

Or install them individually: elliottower/prereg, elliottower/citations, elliottower/results.
