How do I install the Jetpack skill?

Run npx skillmds@latest add majiayu000/jetpack in your terminal (requires Node.js), paste this page's agent-chat prompt into Claude, Cursor, or any MCP-connected agent, or download the SKILL.md file and copy it into your agent's skills directory.

Is Jetpack safe to use?

This skill has not completed SkillMD's automated safety review yet. Independent scanners report: SkillSpector: PASS, Skill Scanner: PASS. Capability flags: makes network calls. SkillMD never runs a skill's scripts for you; review the SKILL.md before installing.

Which AI agents work with Jetpack?

This skill is tagged as working with Claude Code, Claude.ai, OpenAI Codex. SKILL.md is an open format, so most agents that read a skills directory can load it too.

Is Jetpack free to use?

Yes. Installing skills from SkillMD is free, and the skill stays under its author's original license.

Jetpack

Resolves AndroidX/Jetpack library information including version lookup, package-to-Maven-coordinate conversion, and source code downloading. Provides tools for inspecting Jetpack library implementations. Use when working with androidx libraries, resolving Maven coordinates, downloading Jetpack source code, checking library versions (alpha/beta/stable/snapshot), or inspecting AndroidX class implementations. Triggers: androidx, jetpack, maven coordinate, jetpack source, library version, snapshot, alpha, beta.

Jetpack Library Utilities

Important: Use Script First

ALWAYS use scripts/jetpack over raw curl and xmllint commands. The script is located in the scripts/ subdirectory of this skill's folder. It provides features that raw commands do not:

Package-to-coordinate resolution with exceptions table
Version type handling (ALPHA, BETA, STABLE, SNAPSHOT)
Kotlin Multiplatform platform-specific source detection
Build ID resolution for pinned snapshots

When to read the script source: If the script doesn't do exactly what you need, or fails due to missing dependencies, read the script source. It encodes Maven repository URL patterns, version filtering logic, and package naming heuristics—use it as reference when building similar functionality.

Quick Start

Requirements: curl, xmllint (libxml2-utils), jar (JDK).

Highest-Value Commands

Inspect a class (most common): scripts/jetpack inspect androidx.wear.tiles.TileService
Check stable version: scripts/jetpack version androidx.wear.tiles:tiles STABLE
Resolve package to Maven coordinate: scripts/jetpack resolve androidx.lifecycle.ViewModel
Download bleeding-edge source: scripts/jetpack source androidx.compose.ui:ui SNAPSHOT

Subcommand Overview

`version`

Purpose: Get specific version type (ALPHA, BETA, SNAPSHOT, etc.) for a package. Usage: scripts/jetpack version PACKAGE [TYPE] [REPO] Options: ALPHA, BETA, RC, STABLE, LATEST, SNAPSHOT.

`resolve`

Purpose: Convert Android package/class name to Maven coordinate. Usage: scripts/jetpack resolve PACKAGE_OR_CLASS Note: Uses heuristic rules and an exceptions table.

`source`

Purpose: Download and extract source JARs. Usage: scripts/jetpack source PACKAGE... [VERSION] Options: --output DIR to specify destination.

`inspect`

Purpose: Convenience wrapper combining resolve + source. Usage: scripts/jetpack inspect CLASS_NAME [VERSION] Note: Best for quickly checking implementation details.

`resolve-exceptions`

Purpose: Find missing exceptions for the resolve command. Usage: scripts/jetpack resolve-exceptions COORDINATE Note: Analyzes SNAPSHOT JARs to find packages violating naming conventions.

Version Types

Symbolic (Floating)

Resolves to the latest matching version at runtime.

ALPHA: Latest alpha (e.g., 1.2.0-alpha05)
BETA: Latest beta (e.g., 1.2.0-beta02)
RC: Latest release candidate (e.g., 1.2.0-rc01)
STABLE: Latest stable release (e.g., 1.1.0)
LATEST: Latest version of any kind.
SNAPSHOT: Latest build from androidx.dev.

Pinned (Immutable)

Always resolve to the exact same code.

Version String: Specific version (e.g., 1.6.0-alpha01).
Build ID: Specific snapshot build (e.g., 14710011 from androidx.dev/snapshots/builds).

Common Workflows

Inspecting a Class Implementation

cd "$(scripts/jetpack inspect androidx.wear.tiles.TileService)"
# Browse source files...

Checking Available Versions

scripts/jetpack version androidx.wear.tiles:tiles ALPHA
scripts/jetpack version androidx.wear.tiles:tiles SNAPSHOT

Working with Bleeding-Edge Code

scripts/jetpack source androidx.compose.remote:remote-creation-compose SNAPSHOT

Finding Maven Coordinate

scripts/jetpack resolve androidx.core.splashscreen.SplashScreen
# Output: androidx.core:core-splashscreen

Safety Notes

Network Access: Requires access to dl.google.com and androidx.dev.
SNAPSHOTs: Change frequently; use pinned versions or Build IDs for reproducibility.
Kotlin Multiplatform: source and inspect automatically download platform-specific sources (e.g., -android, -desktop) if detected in the POM.
