Reproducible Science

Claude Code plugin

/plugin marketplace add elliottower/reproducible-science

Then install whichever tools you want:

/plugin install reproducible-science@reproducible-science

Or one tool at a time:

/plugin install prereg@reproducible-science
/plugin install citations@reproducible-science
/plugin install results@reproducible-science

Why use it instead of the CLI

Section titled “Why use it instead of the CLI”

The commands are the same. What changes is when they run.

Provenance is easiest to record while the work is happening and hardest to reconstruct afterward — the inputs a run consumed, the outputs it produced, and the order of the two. Used from inside a session, the plugin records that chain as you go, so a claim written into a paper weeks later still has a run behind it.

What you get

Section titled “What you get”

Each plugin carries three surfaces, because each catches a different failure.

surface fires
hook on the tool event, whether or not anyone remembered
skill when Claude judges the situation calls for it
command when you type it

The hooks are the part a CLI cannot do, since each fires at a moment rather than when you think to run something:

hook fires when
frozen plan changed a preregistration no longer matches the digest it was frozen with
unverified quotation a passage enters a manuscript that no claim file pins to a source
unbound number a number enters a manuscript that no recorded claim names

Every hook reports and never blocks, and stays silent in a project that has not opted in: no ledger, no claims directory and no frozen plan means nothing to check and nothing said.

The commands are /prereg-check, /citations-check, /results-check and /repro-check, named alike so there is nothing to remember about which tool answers which question.

Each skill shells out to the published package of the same name, so the CLI has to be installed where Claude is running:

uv tool install reproducible-science   # or: pip install reproducible-science

A project can move between the plugin and the command line without changing anything on disk.

Verifying

Section titled “Verifying”

Verification runs from the command line:

pip install reproducible-science
repro verify
