makepad-2.0-performance
by ZhangHanDongmakepad-2.0-performance is a focused guide for Makepad 2.0 performance and debugging. It helps diagnose draw batching, render triggers, GC behavior, invisible text, UI freezes, and scroll stuttering. Use it when you need practical makepad-2.0-performance usage, install, and troubleshooting steps tied to real rendering issues.
This skill scores 78/100, which means it is a solid directory candidate for agents working on Makepad 2.0 performance and debugging. Users should expect a genuinely useful, install-worthy workflow guide with some caveats: it is actionable and specific, but it would still benefit from clearer quick-start structure and stronger support metadata.
- Strong triggerability: the frontmatter explicitly says to use it for Makepad performance, debug, profiling, GC, batching, and related symptoms like UI freezes and scroll stuttering.
- Good operational depth: the body covers core Makepad subsystems such as draw batching, garbage collection, and render triggers, which gives agents concrete levers instead of generic advice.
- Substantial workflow content: the skill has a long body with multiple headings, code fences, and a dedicated reference guide, suggesting more than a placeholder or demo-only stub.
- Install decision confidence is limited by sparse packaging: there is no install command, and support files are minimal beyond one reference file.
- The description is very terse, and the repository still contains placeholder markers, so users may need to read the skill closely before trusting it for edge-case debugging.
Overview of makepad-2.0-performance skill
What this skill is for
The makepad-2.0-performance skill is a focused guide for diagnosing and improving Makepad 2.0 rendering, batching, GC, and debugging issues. It is most useful when you need to understand why a UI is slow, why text or views disappear, or why a layout behaves differently after a render change. This is not a general Makepad tutorial; it is meant for performance work where makepad-2.0-performance matters because the bug is usually tied to batching order, render triggering, or VM memory behavior.
Who should use it
Use the makepad-2.0-performance skill if you are already building with Makepad and need a practical path from symptom to root cause. It fits developers who can describe a concrete failure like stuttering scroll, invisible labels, or unexpected redraws, and want a guide that helps them debug rather than guess.
Main differentiators
The skill’s value is its narrow scope: it centers on new_batch: true, draw batching rules, render invalidation, and GC behavior in the Splash VM. Those are the areas most likely to block adoption of Makepad apps when ordinary prompt advice does not expose the real cause.
How to Use makepad-2.0-performance skill
Install and activate it
For makepad-2.0-performance install, add the skill to your workspace with the repository’s skill manager flow, then open skills/makepad-2.0-performance/SKILL.md as the primary entry point. The install is only useful if the skill is actually invoked on a performance or debugging task, so make sure your prompt names the symptom and the Makepad context clearly.
Start with the right files
Read SKILL.md first, then references/optimization-guide.md. Those two files give you the working model you need before you apply the skill. If you are scanning for the shortest route to understanding, begin with the batching section and the notes around new_batch: true, because that is one of the highest-impact fixes for ordering bugs.
Turn a vague request into a usable prompt
The makepad-2.0-performance usage pattern works best when you specify:
- the visible problem:
text disappears,UI freezes,scroll stuttering, orrender treeconfusion - the trigger:
draw batching,mod.gc,debug logging, oron_render - the context: whether the issue happens in a list, overlapping views, or a redraw-heavy screen
A stronger prompt looks like: “Debug a Makepad 2.0 screen where text vanishes only when sibling views overlap; check batching order and whether new_batch: true is needed.” That is better than “Makepad UI bug” because it gives the skill a concrete failure mode and a likely mechanism.
Practical workflow for better output
Use the skill as a diagnostic workflow:
- describe the symptom and where it appears
- identify whether the issue is visual, redraw-related, or memory-related
- ask for the likely subsystem first, not a full rewrite
- validate the suggested fix against your actual widget tree
If the issue is performance, include the part of the tree that repeats, scrolls, or rebuilds often. If it is debugging, include the smallest code path that reproduces the problem. That helps the skill distinguish batching problems from GC pauses or incorrect render triggers.
makepad-2.0-performance skill FAQ
Is this only for performance work?
No. The makepad-2.0-performance skill also helps with debugging symptoms that look like performance problems but are really draw-order or render-trigger issues. It is especially useful when ordinary prompt help fails to connect the symptom to Makepad’s batching model.
When should I not use it?
Do not use it for generic Rust questions, unrelated UI frameworks, or broad Makepad feature requests that are not about rendering behavior, GC, or debug diagnosis. If you only need a quick syntax reminder, this skill is more specialized than necessary.
Is it beginner-friendly?
Yes, if you can describe what is broken. You do not need deep renderer knowledge to benefit from the makepad-2.0-performance guide, but you do need enough context to show the failing screen, the repeated widget pattern, or the trigger that causes the regression.
How is it different from a normal prompt?
A normal prompt often asks for a fix without naming the subsystem. This skill is built to steer the investigation toward batching, memory, and render lifecycle issues first, which usually produces a more accurate root cause and fewer false leads.
How to Improve makepad-2.0-performance skill
Provide the symptom, not just the goal
The best results come from concrete failure descriptions: which widget disappears, what action triggers the freeze, and whether the issue happens only after scrolling, hovering, or rebuilding. For makepad-2.0-performance for Debugging, the symptom is often more important than the code style.
Include the structure that affects batching
Batching issues depend on sibling order, shared shaders, overlapping backgrounds, and whether a subtree needs its own batch. If you want better help, show the widget hierarchy around the problem, not just the single component you suspect.
Tell the skill what changed
If the bug started after a refactor, mention what changed: added a container, moved a label, changed a shader, or altered render invalidation. That makes it easier to separate a real regression from an existing limitation of the Makepad pipeline.
Iterate with a targeted repro
If the first answer is too general, shrink the case to one screen and one failing interaction. Then re-run the makepad-2.0-performance usage workflow with logs, a minimal tree, or the exact overlap pattern. The more exact your repro, the faster this skill can narrow the fix.
