Android Skills

Improve how AI coding assistants write your Android code by giving them specialized, platform-approved instructions. The skills repository provides modular, markdown-based guides designed to ground large language models in tricky, specialized areas where they traditionally struggle, like complex camera setups, background performance, and Jetpack Compose transitions. Instead of relying on general training data, you can feed these precise templates directly to your AI tools to ensure they follow modern, error-free patterns. It is an easy way to get smarter, more accurate code generation. Grab these official resources to make your AI assistant a true Android expert.

📦 vercel-labs/just-bash

just-bash

This TypeScript package runs a fully simulated bash environment inside an in-memory virtual filesystem with absolutely zero external dependencies. It is built specifically for AI agents that need a secure space to run terminal scripts without putting the host computer at risk. Instead of spinning up heavy virtual machines, it acts as a sandboxed interpreter that parses and runs commands safely. It blocks path traversal attacks, restricts network access, and neutralizes dangerous terminal actions out of the box. It is the perfect lightweight solution for giving your AI tools terminal capabilities without compromising your system security.

📦 open-telemetry/semantic-conventions-genai

Semantic Conventions GenAI

Semantic-conventions-genai is the OpenTelemetry extension that finally brings standard, structured tracking to artificial intelligence applications. When you build with large language models, agents, or tools, figuring out why a request failed or where a bottleneck happened is incredibly difficult because every framework talks about data differently. This project solves that by defining a universal language for AI telemetry, mapping things like prompt versions, token counts, and memory operations into consistent metrics and events. The single most impressive thing it does is establish a strict, runtime-testable blueprint for tracking complex multi-agent workflows and tool executions. This means you can easily monitor your AI applications across different cloud providers and model families...

📦 browser-act/skills

Skills

AI agents struggle with traditional web browsers because typical automation tools get blocked by bot detectors and cannot handle unexpected visual challenges. The open source project skills changes this by providing a specialized command line browser built from the ground up for artificial intelligence. If an agent gets stuck on a tricky verification screen, it generates a secure link allowing a human to take over from any device and click through the barrier before handing control back to the AI. It also outputs clean, indexed text instead of heavy code, making web navigation incredibly easy and cost-effective for language models.

📦 capitalone/vulnhunter

VulnHunter

VulnHunter is an open-source security tool that thinks like an actual attacker to find real security flaws in your source code. Instead of acting like traditional scanners that flood your screen with fake warnings, it flips the script. It starts at public-facing entry points, like APIs or file uploads, and traces forward to see if a hacker could actually break in. It even uses a clever falsification engine to double-check itself, trying to disprove its own findings before bothering you. When it finds a real bug, it writes a proof-of-concept exploit, patches the code, and verifies the fix is safe.

Unigent

Unigent is the cross-harness SDK that finally lets you build stateful agent workflows using ordinary TypeScript. Instead of wrestling with complex frameworks or manual string parsing, you write simple functions and let the SDK automatically extract your TypeScript signatures to generate clean tool definitions. You can spin up conversational agents, effortlessly fork sessions to explore different paths simultaneously without duplicating context, and get strictly typed outputs directly from your models. There is even a live trace terminal inspector to watch your agents work in real-time. Give it a spin to build smarter, self-correcting automation scripts today.

percentify

Most data-profiling tools bury you in massive, hard-to-read reports, but percentify takes a completely different approach by giving you a single-line data diagnostician that tells you exactly what to fix before you model. Instead of just describing what your dataset is, its flagship profiler function ranks every data issue from worst to first and pairs each with a concrete suggestion on how to solve it.
