How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file
We split this skill into the rules it gives an agent
3 rules. 0 are common, 3 are distinctive, and 0 are very specific to this project.
0
Common
Most of the 7 edited versions we read keep these.
3
Distinctive
This author's own choices. Worth a look.
0
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Distinctive: line 11
If that names a file, read it.
- Distinctive: line 40
if it fails, what the evidence actually says instead
- Distinctive: line 48
Do not rewrite the user's document unless they ask.
“Common” is measured: kept by at least 6 in 10 of the 7 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.
Files
Ground a document's claims
Target: $ARGUMENTS
If that names a file, read it. If it is a claim written out, work on that. If it is empty, use the document currently in context, and ask which one only if that is genuinely ambiguous.
What to do
- Extract the empirical claims. Statements that assert something checkable about the world: an effect, a magnitude, a mechanism, a comparison, a rate. Skip definitions, opinions, and statements of intent. Aim for the load-bearing ones rather than every sentence; a claim is load-bearing if the argument fails when it fails. List them for the user before you start checking, numbered.
- Work out the era. For each claim, decide the year it should be judged against.
Usually that is the publication year of the source it rests on, or the year the
document is about. Pass it as
as_of. This matters more than it sounds: unfenced retrieval on an older claim buries the primary report under everything published since. - Check each claim.
zetesis_scope, thenzetesis_evidencewith short entity-anchored queries, then grade against what came back. Work through them in order and report as you go rather than saving everything for the end. If a claim concerns funding, competitive position, or a company's standing, append the entity-only terms toqueriesand setinclude_capital: true; it is off by default and without it no grant or filing id can appear. - Report per claim, briefly:
- the claim, quoted or tightly paraphrased
- whether the retrieved evidence supports it, partly supports it, or does not reach it
- the hard ids that bear on it
- if it fails, what the evidence actually says instead
Rules
Cite only ids that came back in a bundle. If nothing relevant was retrieved for a claim, say exactly that rather than filling the gap from memory; "no retrieved evidence bears on this" is a legitimate and useful result.
Do not rewrite the user's document unless they ask. The output is an assessment.
Close with the claims that need the author's attention first, ordered by how much the argument depends on them.
Does it work?

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
