Expert for developing Streamlit data apps for Keboola deployment. Activates when building, modifying, or debugging Keboola data apps, Streamlit dashboards, adding filters, creating pages, or fixing data app issues. Validates data structures using Keboola MCP before writing code, tests implementations with Playwright browser automation, and follows SQL-first architecture patterns.
Comprehensive security and authentication workflow that orchestrates security architecture, identity management, access control, and compliance implementation. Handles everything from authentication system design and authorization frameworks to security auditing and threat protection.
Build modern, interactive terminal user interfaces with Textual. Use when creating command-line applications, dashboard tools, monitoring interfaces, data viewers, or any terminal-based UI. Covers architecture, widgets, layouts, styling, event handling, reactive programming, workers for background tasks, and testing patterns.
Comprehensive thoroughness framework. Auto-invoked when planning features, implementing code, fixing bugs, writing tests, analyzing existing code, auditing features, reviewing architecture, or investigating issues. Forces systematic consideration of all edge cases, failure modes, error scenarios, security implications, state transitions, and hidden assumptions so nothing gets missed. Do NOT invoke for trivial changes like typos, renames, single-line fixes, adding imports, or updating config values.
