What is avalonia-pro-max?

Design guidance for making Avalonia apps consistent and polished, including colors, typography, spacing, themes, animations, accessibility, and responsive layouts.

Use it when creating or restyling screens, selecting a theme library, building reusable controls, supporting light and dark modes, or improving a cross-platform app.

It gives developers a shared set of visual and interaction decisions instead of leaving each screen to look different.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00072	$0.01969
Opus 5.5	$0.00029	$0.00788
Sonnet 5.5	$0.00014	$0.00394
Haiku 4.5	$0.00007	$0.00197

Measured 9d ago against content hash 86c0261e36ff, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

avalonia-pro-max scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (preview-server/scripts/render_variants.py, preview-server/scripts/scaffold_host.py, preview-server/scripts/serve_gallery.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Avalonia Pro Max — Beautiful Avalonia UIs

Purpose

avalonia skills teach you the framework. avalonia-pro-max teaches you to make it look and feel professional: design tokens, theme selection, component recipes, motion, accessibility, responsive layout, icons, and final QA.

This skill is the desktop/cross-platform counterpart to ui-ux-pro-max. Same priorities, but every rule is mapped to Avalonia 12.x (XAML, FluentTheme, ControlThemes, pseudoclasses, AutomationProperties, etc.).

Avalonia Versions

Supports Avalonia 11.3, 12.0 and 12.1 (latest 12.1.4). Detect the project's version first and use the avalonia-versions skill (version matrix, renamed APIs, label convention). In these sub-skills: (12.0+) / (12.1+) = needs that version or newer, (11.x) = 11.x only (removed/obsolete in 12), no label = works in 11.3, 12.0 and 12.1. Never mix 11.x and 12.x APIs. No project yet → 12.1.x on net10.0.

When to Use

Must use

Building a new screen, window, or page
Restyling an existing app or replacing the default look
Choosing a theme library (FluentAvalonia, SukiUI, Semi, Material, ShadUI, Ursa…)
Defining colors, typography, spacing, radius, elevation tokens
Adding animations, transitions, hover/press states
Implementing dark/light theme variants
Reviewing UI before shipping or PR
The user says "make this beautiful", "modernize", "polish", "looks bland"

Skip

Pure data binding, MVVM plumbing, services, deployment — use base avalonia subskills

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
