This project contains 50 AI Reference documents for Apple frameworks. When asked about iOS/Apple framework development, consult the relevant document in ai-reference/:
We split this CLAUDE.md into the rules it gives an agent
6 rules. About 0 are common, 4 are distinctive, and 2 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈4
Distinctive · estimate
This author's own choices. Worth a look.
2
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Very specific: line 7
When asked about iOS/Apple framework development, consult the relevant document in ai-reference/:
- Very specific: line 11
Read the corresponding ai-reference/{framework}.md
- Distinctive: line 12
Use it as context to generate production-quality Swift/SwiftUI code
- Distinctive: line 70
Use Swift Concurrency (async/await, Actor)
- Distinctive: line 71
Follow SwiftUI best practices
- Distinctive: line 73
Add accessibility support (VoiceOver)
≈ “Common” is an estimate: at least 1 in 5 of the 25,680 CLAUDE.md 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.

Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
Reviews can't be read right now.
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.
