Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00134 | $0.03762 |
| Opus 5.5 | $0.00054 | $0.01505 |
| Sonnet 5.5 | $0.00027 | $0.00752 |
| Haiku 4.5 | $0.00013 | $0.00376 |
Grade A, and why
android-java-bindings 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 13d ago.
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.
How it starts
The opening of the file, as written. The whole thing — 329 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Java and Kotlin bindings for C#
Purpose and scope
Create maintainable .NET for Android binding libraries from existing Java/Kotlin artifacts. Preserve the native contract and the requested C# API, not merely a successful build. These bindings can be consumed by .NET Android or the Android target of a MAUI app; they do not make an Android SDK cross-platform.
Use this workflow for direct bindings and generated-code troubleshooting. If the
user only needs a small facade around a complex SDK, explain the tradeoff and use
android-slim-bindings for wrapper construction. Do not silently replace an
existing full binding with a smaller wrapper or remove required APIs.
Choose the entry point
- New binding: follow the workflow from artifact inspection.
- An existing binding error: start with the failing stage and repair recipes below. Do not scaffold a project or run Gradle unless dependency evidence calls for it.
- A question with supplied signatures/errors: give the concrete transform or addition and explain its limits using those facts. Do not search an empty workspace for hypothetical artifacts. Ask for missing declarations only when they affect the repair.
The core decisions and recipes are included here so routine troubleshooting does not depend on extra file reads. The references at the end provide deeper examples when needed; load only the relevant one, relative to this skill's base directory. If a reference cannot be read, state that limitation and use the guidance below rather than guessing metadata attributes or repeatedly trying unrelated paths.
Inputs
Determine from the workspace, artifacts, and user:
- Exact Maven coordinates/version/repository, or local AAR/JAR and its provenance.
- Required types, methods, callbacks, and whether an existing public API must stay compatible. Distinguish required coverage from optional APIs.
- Binding project, SDK/workload/TFM, configuration, and supported Android versions.
- For repairs: first error, generator warnings, diagnostic build log, metadata, additions, and generated declarations on both sides of the failing contract.
- For Kotlin: JVM/Android artifact variant, Kotlin version, and source if available.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

android-java-bindings is a skill published in the GitHub repository dotnet/maui-labs (226 stars, last pushed today), licensed MIT. It adds 134 tokens to every session and 3,762 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-03.
