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, 2 are distinctive, and 1 is very specific to this project.
0
Common
Most of the 6 edited versions we read keep these.
2
Distinctive
This author's own choices. Worth a look.
1
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Distinctive: line 22
Do NOT mix langchain v0.2 with langgraph v0.3.
- Distinctive: line 23
Do NOT install langchain-experimental unless specifically needed.
- Very specific: line 24
Use langchain-anthropic (not langchain-community ChatAnthropic) for Anthropic models.
“Common” is measured: kept by at least 6 in 10 of the 6 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.

- Do NOT mix langchain v0.2 with langgraph v0.3. They are incompatible.
- Do NOT install langchain-experimental unless specifically needed. It pulls heavy deps.
- Use
langchain-anthropic(notlangchain-communityChatAnthropic) for Anthropic models. - Pin
pydantic>=2.0. LangChain v0.3 requires Pydantic v2.

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.
