F-Droid inclusion skill for Claude Code — non-free deps, foss flavour

Finds every Gradle line that keeps your Android app out of F-Droid

fdroid-inclusion-check - findings on the bundled example

On one 40-line app/build.gradle.kts it printed 14 findings (10 errors, 4 warnings) from 25 rules, each with file:line and the free replacement.

Get it on Whop - $12 once Get it on Gumroad

Who it's for

For Android maintainers who want their app in F-Droid while the Play build keeps Firebase and Play Services.

What breaks, and when

While one non-free artifact sits on an unflavoured line, fdroidserver's scanner rejects the build; apps built on AdMob are not found in the F-Droid repo at all.

What you get

A scanner Claude runs over every .gradle, .kts and .toml file - not a guess from memory
25 rules from the F-Droid Inclusion Policy and fdroidserver scanner.py: GMS, Firebase, Play Core, Billing, ML Kit
Each finding names its anti-feature and a free swap: UnifiedPush, ACRA, osmdroid, ZXing
Claude drafts the foss/play flavour split and edits only after you say yes; exit 1 in CI on any error

Install

Unzip into ~/.claude/skills/ (all projects) or your-repo/.claude/skills/ (one repo), then ask Claude Code: "We want to publish our Android app on F-Droid but it uses Firebase and Google Play Services. Can you go through our Gradle files and tell me what they would reject and what a foss build would need instead? Don't edit anything yet.". Needs Node 16+.

unzip fdroid-inclusion-check.zip -d ~/.claude/skills/

Ask Claude

“We want to publish our Android app on F-Droid but it uses Firebase and Google Play Services. Can you go through our Gradle files and tell me what they would reject and what a foss build would need instead? Don't edit anything yet.”

What it does not do

Reads Gradle text only; it does not run Gradle, resolve transitive dependencies or scan .aar/.jar binaries.

FAQ

What is a Claude Code skill?

A folder with a SKILL.md and scripts that Claude Code loads when your request matches it. You ask in plain words and Claude runs the scanner the skill carries.

How is this different from asking Claude without the skill?

The skill carries a dated rule table and a scanner that reads every file, so Claude quotes the exact date and line instead of answering from memory.

Does it send my code anywhere?

Reads Gradle text only; it does not run Gradle, resolve transitive dependencies or scan .aar/.jar binaries.

How do I install it?

What do I get when I buy?

The zip. On Whop it is in your library as a download lesson with the zip attached; on Gumroad it is the product file.
