Reusable SKILL.md capabilities that give your agent new expertise — installed into .claude/skills/ and friends.
Run agent-browser on AWS Bedrock AgentCore cloud browsers. Use when the user wants to use AgentCore, run browser automation on AWS, use a cloud browser with AWS credentials, or needs a managed browser session backed by AWS infrastructure. Triggers include "use agentcore", "run on AWS", "cloud browser with AWS", "bedrock browser", "agentcore session", or any task requiring AWS-hosted browser automation.
Node.js development principles and decision-making. Framework selection, async patterns, security, and architecture. Teaches thinking, not copying.
Builds Flutter layouts using the constraint system and layout widgets. Use when creating or refining the UI structure of a Flutter application.
Architects a Flutter application using the recommended layered approach (UI, Logic, Data). Use when structuring a new project or refactoring for scalability.
Gmail: Read a message and extract its body or headers.
Manages application and ephemeral state in a Flutter app. Use when sharing data between widgets or handling complex UI state transitions.
Customizes the visual appearance of a Flutter app using the theming system. Use when defining global styles, colors, or typography for an application.
Handles routing, navigation, and deep linking in a Flutter application. Use when moving between screens or setting up URL-based navigation.
Implements animated effects, transitions, and motion in a Flutter app. Use when adding visual feedback, shared element transitions, or physics-based animations.
Use when running OpenCLI commands to interact with websites (Bilibili, Twitter, Reddit, Xiaohongshu, etc.), desktop apps (Cursor, Notion), or public APIs (HackerNews, arXiv). Covers installation, command reference, and output formats for 79+ adapters.
Implements unit, widget, and integration tests for a Flutter app. Use when ensuring code quality and preventing regressions through automated testing.
Use when quickly generating a single OpenCLI command from a specific URL and goal description. 4-step process — open page, capture API, write TS adapter, test. For full site exploration, use opencli-explorer instead.
Automatically fix broken OpenCLI adapters when commands fail. Load this skill when an opencli command fails — it guides you through diagnosing the failure via OPENCLI_DIAGNOSTIC, patching the adapter, and retrying. Works with any AI agent.
Measures and optimizes the size of Flutter application bundles for deployment. Use when minimizing download size or meeting app store package constraints.
Implements caching strategies for Flutter apps to improve performance and offline support. Use when retaining app data locally to reduce network requests or speed up startup.
Builds Flutter forms with validation and user input handling. Use when creating login screens, data entry forms, or any multi-field user input.
Executes HTTP requests and handles JSON serialization in a Flutter app. Use when integrating with REST APIs or parsing structured data from external sources.
Manages local data persistence using SQLite or other database solutions. Use when a Flutter app needs to store, query, or synchronize large amounts of structured data on the device.
Executes long-running tasks in background isolates to keep the UI responsive. Use when performing heavy computations or parsing large datasets.
Configures a Flutter app to support multiple languages and regions. Use when preparing an application for international markets and diverse user locales.
Builds Flutter plugins that provide native interop for other apps to use. Use when creating reusable packages that bridge Flutter with platform-specific functionality.
Interoperates with native platform APIs on Android, iOS, and the web. Use when accessing device-specific features not available in Dart or calling existing native code.
