Debug Makepad Code and Improve Quality

Makepad Reference is a central quick-reference and debugging hub for the Makepad Rust UI framework, distinct from the specialized subsystem skills (basics, DSL, layout, animation, events, fonts, shaders, deployment) in that it's oriented toward diagnosis and lookup rather than writing a focused feature in one subsystem. It provides a navigation table pointing to four reference categories - API documentation lookup, troubleshooting for build/runtime failures, Makepad-aware code-quality refactoring, and adaptive desktop/mobile responsive layout patterns - as a starting point before diving into a more specialized Makepad skill.

Its common-issues quick-reference table covers five recurring problems with their fixes: a "no matching field: font" error (use text_style: <THEME_FONT_*>{} instead), a color-parse error when a hex color ends in e (change the last digit, e.g. #14141e to #14141f), a set_text call missing an argument (add cx as the first argument), UI not updating after a state change (call redraw(cx) explicitly), and a widget-not-found error (check ID spelling and use the ids!() macro for widget paths).

### Run with line info for better error messages
MAKEPAD=lines cargo +nightly run

// Add logging
log!("Value: {:?}", my_value);
log!("State: {} / {}", self.counter, self.is_loading);

It links out to the official Makepad documentation (an Obsidian-published docs site), the Makepad GitHub repository, and two production reference codebases - Robrix and Moly - as real-world examples of Makepad apps to study for patterns beyond the SKILL.md's own scope.

Use this skill when you need quick-reference material for common Makepad errors, debugging, or API lookups, or when the task is diagnostic/reference-oriented rather than writing a focused feature within one specific Makepad subsystem - use it as a central starting point before reaching for a more specialized Makepad skill.

It is not a substitute for the specialized Makepad skills (basics, DSL, layout, animation, events, fonts, shaders, deployment) for actually implementing a feature, nor for environment-specific validation, testing, or expert review of a fix.

Inputs: a Makepad build error, runtime bug symptom, or a general question about where to find API documentation or production examples.

Outputs: a quick-fix for a recognized common error, a debug command or logging snippet, or a link to the relevant official documentation or production reference codebase.

Points to the official Makepad documentation site, the Makepad GitHub repository, and the Robrix and Moly production reference apps; serves as the entry point to the rest of the Makepad skill family (basics, DSL, layout, animation, event/action, font, shader, deployment).

Makepad developers hitting a build or runtime error, looking for a quick API lookup, or wanting a starting point before diving into a more specialized Makepad skill.
