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

5 rules. About 0 are common, 5 are distinctive, and 0 are very specific to this project.

≈0
Common · estimate
Many files like this have a rule of this kind.
≈5
Distinctive · estimate
This author's own choices. Worth a look.
0
Very specific
Tied to their project's names, files or tools. Probably skip.

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

List Building Pro Tips

Core Principles

1. Mix Sources

Don't rely on just one data provider
Each source has different strengths/coverage
Combine for maximum coverage

2. Scraping = Step 1

Raw scraped data is just the beginning
Still need Clay enrichment for:
- Email verification
- Phone numbers
- Company data
- Custom signals

3. Templates Are Modular

Start with proven templates
Adjust for specific campaign goals
Don't rebuild from scratch

4. Don't Reinvent the Wheel

Use existing Clay templates
Modify rather than create
Learn from what works

Data Quality Hierarchy

1. Verified email (bounced < 2%)
2. Direct phone number
3. Recent activity signal
4. ICP fit confirmed
5. Company enrichment complete

Efficiency Benchmarks

Task	Manual Time	With Clay
100 prospects	8-10 hours	30 min
500 prospects	40+ hours	1-2 hours
1000 prospects	80+ hours	2-3 hours

Quality Checklist

Before launching any campaign:

Email bounce rate < 2%
At least 70% email coverage
ICP criteria verified
Recent signals tagged
Duplicates removed
Competitor customers flagged
Do-not-contact list checked

Common Mistakes

Single source reliance - Limits coverage
Skipping verification - Kills deliverability
Over-filtering - Shrinks TAM too much
Under-filtering - Wastes outreach on bad fits
Ignoring signals - Missing hot prospects

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

It worked
Partly
It didn't

What did you use it for? e.g. Reviewing pull requests in a Rails app

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.
