android-modernization-upgrade is a skill for Codex from krutikJain/android-agent-skills. It costs 38 tokens per session (1,430 once invoked), scanned A, original, MIT.

A migration guide for bringing an old Android project onto a currently supported toolchain and replacing outdated APIs.

In plain words
What is it for?
Use it to plan staged Android, Gradle, Android Gradle Plugin, and Kotlin upgrades, replace deprecated classes, and check 16 KB alignment.
Why use it?
Older Android projects often break during version upgrades and may depend on APIs or build settings that are no longer supported.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

android-modernization-upgrade scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

The scan reads SKILL.md. This mod also ships 5 executable files (scripts/apply_safe_upgrades.py, scripts/build_compat_matrix.py, scripts/check_16kb_alignment.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Android Modernization Upgrade

When To Use

  • Use this skill when the request is about: upgrade old android project, fix android build after agp or kotlin bump, replace deprecated android classes.
  • Primary outcome: Bring very old Android projects to a current supported baseline with staged upgrades, deprecated API replacement, 16 KB alignment checks, and explicit handoff to specialized skills.
  • Purpose: end-to-end guidance for bringing very old Android projects to a current supported baseline.
  • Reach for this skill when the request is repo-wide compatibility and staged upgrade sequencing, not isolated Kotlin cleanup or one-library refactoring.
  • Trigger language: requests about upgrading old Android codebases, fixing breakage after version bumps, migrating deprecated Android patterns, replacing deprecated classes, resolving old Gradle/AGP/Kotlin issues, handling 16 KB alignment, or modernizing architecture/setup.
  • Handoff skills when the scope expands:
  • android-gradle-build-logic
  • android-viewsystem-foundations
  • android-compose-xml-interoperability
  • android-security-best-practices
  • android-performance-observability
  • android-rxjava-to-coroutines-migration

Responsibilities

  • Diagnose the repository shape: AGP, Gradle, Kotlin, AndroidX/support libraries, SDK levels, native artifacts, and deprecated APIs/classes.
  • Generate a safe upgrade sequence instead of bumping everything at once.
  • Branch the migration path for Compose-heavy, View-system, and mixed interoperability projects.
  • Replace deprecated imports and classes when the fix is deterministic; otherwise emit an explicit remediation item.
  • Verify native packaging and 16 KB alignment readiness before release.
  • Hand off focused follow-up work to the right specialized Android skills once the main upgrade blockers are isolated.

Workflow

  1. Scan the project to understand toolchain age, AndroidX status, native packaging, and deprecated APIs.
  2. Generate an ordered modernization plan that isolates mechanical fixes from risky semantic changes.
  3. Apply deterministic upgrades in small stages and rerun build, test, and lint after each stage.
  4. Route remaining failures to the owning specialized skills with exact issue signatures and file paths, including RxJava chains that should move to the dedicated migration skill.
  5. Produce a final remediation report that leaves no hidden migration debt.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
