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, 0 are distinctive, and 1 is very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈0
Distinctive · estimate
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
- Very specific: line 28
Check the AGP, Kotlin, Compose BOM and compileSdk/targetSdk versions in the build files and version catalog.
≈ “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.

Mobile Android
Guides for building native Android apps, most of them from the Android team (android/skills). Cross-platform topics live in their own skills and have Android references there: architecture in mobile-architecture, tests in mobile-test, debugging (Gradle, crashes, ANRs) in mobile-debug, code review in mobile-code-review, security in mobile-security and Firebase in mobile-firebase.
Pick the topic
| Topic | Read |
| UI and navigation | references/ui.md |
| Build, performance and tooling | references/build-and-performance.md |
| Google Play | references/play.md |
| Identity | references/identity.md |
| Camera and media | references/media.md |
| On-device AI | references/on-device-ai.md |
| Other form factors | references/devices.md |
Each topic file lists its guides; open only the ones the task needs.
Before writing code
- Check the AGP, Kotlin, Compose BOM and
compileSdk/targetSdkversions in the build files and version catalog; several guides depend on minimum versions. - Several guides prescribe running specific tools or scripts and following steps strictly; run what writes files only with the user's agreement.
Interface design
For UI/UX reviews, wireframes, design systems and screen redesigns, use mobile-ui-ux and its reference for this stack. For Apple targets, also consult its Apple design workflow; validate platform claims against current official guidance and the installed toolkit.
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.

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.
