Tuxido

What it does

Tuxido renders an interactive validation and code-generation UI inside MCP clients, letting developers validate Textual TUI Python code across four depth levels, generate working TUI apps from ASCII mockups, and auto-heal common errors — all driven by AI through MCP tools.

Key features

• 4-level validation — L1 syntax (AST), L2 static analysis (unsafe imports, async), L3 DOM/widget tree, L4 sandbox runtime testing
• ASCII-to-code generation — Draw a mockup in ASCII art, run tuxido generate, and get a working Textual app with proper widget hierarchy
• Self-healing — Iterative auto-fix for common errors: forbidden imports, missing widget IDs, unused imports, with up to configurable max iterations
• MCP tools — validate_tui and get_framework_info tools expose validation and Textual widget reference directly to AI assistants
• OpenCode/Claude/Cursor integration — Ships with config snippets for multiple MCP hosts plus an auto-installing skill with 20+ widget references and code patterns
