Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00000 | $0.03058 |
| Opus 5.5 | $0.00000 | $0.01223 |
| Sonnet 5.5 | $0.00000 | $0.00612 |
| Haiku 4.5 | $0.00000 | $0.00306 |
Grade A, and why
avalonia-controls-layout 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.
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.
How it starts
The opening of the file, as written. The whole thing — 343 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Avalonia Layout Controls
Overview
Layout controls are containers that position and constrain child controls. See avalonia-layout for general sizing/alignment concepts. This skill covers the container control APIs.
Border
Single-child container. Adds background, border, rounded corners, padding, and shadows.

Padding="16"
BoxShadow="0 2 8 0 #20000000">
<StackPanel Spacing="8">
<TextBlock Text="Card Title" FontWeight="SemiBold" FontSize="16"/>
<TextBlock Text="Card body content goes here." TextWrapping="Wrap"/>
</StackPanel>
</Border>
<!-- Divider line using Border -->
<Border Height="1" Background="#E0E0E0" Margin="0,8"/>
<!-- Multiple box shadows -->
<Border BoxShadow="0 1 3 0 #1A000000, 0 4 6 0 #0D000000" CornerRadius="6" Padding="12">
<TextBlock Text="Elevated card"/>
</Border>
Important:
Borderonly accepts one child. Wrap multiple children in aPanel,StackPanel, orGrid.

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.

avalonia-controls-layout is a skill published in the GitHub repository linuxdevel/Avalonia-skills (48 stars, last pushed 10d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 3,058 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
