Skill UI

Provides cross-language patterns for developing memory-safe systems code. This skill covers crucial concepts like RAII, ownership models, smart pointers, and robust resource management. It is essential for preventing common vulnerabilities such as use-after-free, memory leaks, and ensuring reliable resource handling across complex systems.

This skill covers designing visible and recoverable error handling for n8n workflows. It focuses on using error outputs, retry mechanisms, and Error Trigger workflows to prevent silent failures in unattended automation. Learn how to configure node-level retries and wire error paths correctly to ensure alerts and diagnostics are exposed only when necessary.

Best practices for event handling and custom action patterns in Makepad/Robius applications, covering widget actions, centralized App action handling, MatchEvent, and widget-to-widget communication.

Build production-ready Slack apps using the Bolt framework in Python, JavaScript, or Java. Covers Block Kit rich UIs, interactive components, slash commands, event handling, OAuth installation flows, and Workflow Builder integration.

Manage ownership, retention, and cleanup of downloaded weather data across one-shot jobs, interactive viewers, caches, failures, and cancellation. This skill ensures temporary files are removed after use, interactive data persists until closed, and shared caches are protected. It covers Python implementation for safe file handling, atomic moves, and idempotent cleanup logic to prevent data leaks or corruption during processing.

A critical skill for reviewing WooCommerce extensions, payment integrations, and checkout logic before deployment. Ensures code follows security standards, HPOS compatibility, proper data handling, and runtime discipline to prevent systematic AI failures.
