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
1 rule. About 0 are common, 1 is distinctive, and 0 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈1
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
- Distinctive
- Very specific
- Distinctive: line 26
Read the one that matches what you are doing:
≈ “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.

Python Standards
The Python delta over the always-loaded rules in .claude/rules/common/. Nothing here restates a
rule from common/ — read this alongside it, not instead of it.
What applies immediately
- Annotate every public signature, parameters and return type. No bare
Anyto appease the type checker — use a precise type, aProtocol, or a generic. - PEP 8 naming:
snake_casefor functions and modules,PascalCasefor classes,UPPER_SNAKE_CASEfor constants. The naming section incommon/coding-style.mdis JS/TS-flavored and does not apply here. - Frozen dataclasses for values you pass around or expose.
- Fail fast on missing secrets —
os.environ["KEY"]raises at startup; beyond a small script use a typed settings object. - Formatting is not your job:
black,isort, andruffown it. Configure them inpyproject.toml; do not hand-maintain PEP 8 details.

Building a FastAPI service? The standards-fastapi skill extends this one with layering, async
SQLAlchemy, and request/response model rules.
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

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.
