Getting it into your agent
There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

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 | $0.00059 | $0.02778 |
| Opus 5 | $0.00030 | $0.01389 |
| Sonnet 5 | $0.00012 | $0.00556 |
| Haiku 4.5 | $0.00006 | $0.00278 |
Grade A, and why
avalonia-controls-media 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 8d 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.

Avalonia Media Controls
Overview
Media controls display images, vector graphics, and embedded web or video content. Image sources use avares:// URIs for app assets. Vector content (PathIcon, DrawingImage) scales without pixelation.
Image
Displays raster (PNG, JPEG, BMP, WebP) or vector images.
| Property | Type | Notes |
|---|---|---|
Source |
IImage |
Bitmap, DrawingImage, bound IImage |
Stretch |
Stretch |
None, Fill, Uniform (default), UniformToFill |
Width / Height |
double |
Explicit size; required if parent gives infinite space |
RenderOptions.BitmapInterpolationMode |
BitmapInterpolationMode |
Default, LowQuality, MediumQuality, HighQuality, None |
Stretch modes:
| Value | Behavior |
|---|---|
None |
Original pixel size |
Fill |
Stretches to fill, distorts aspect ratio |
Uniform |
Letterboxed to fit, preserves aspect ratio |
UniformToFill |
Fills area, may clip, preserves aspect ratio |
Loading from app assets (AXAML):
<!-- Bundled asset — requires Build Action: AvaloniaResource -->
<Image Source="avares://MyApp/Assets/logo.png" Width="120" Height="40" Stretch="Uniform"/>
<!-- Relative path from project root (works at design time, runtime needs avares://) -->
<Image Source="/Assets/banner.jpg" Stretch="UniformToFill"/>
Loading in code:
using Avalonia.Platform;
using Avalonia.Media.Imaging;
// From app assets
var uri = new Uri("avares://MyApp/Assets/logo.png");
var bitmap = new Bitmap(AssetLoader.Open(uri));
myImage.Source = bitmap;
// From file system
var bitmap = new Bitmap("/home/user/photo.png");
myImage.Source = bitmap;
// From stream
using var stream = File.OpenRead(path);
var bitmap = new Bitmap(stream);
Binding to ViewModel:
// In ViewModel
private Bitmap? _photo;
public Bitmap? Photo
{
get => _photo;
set => SetProperty(ref _photo, value);
}
// Load async
public async Task LoadPhotoAsync(string path)
{
await using var stream = File.OpenRead(path);
Photo = await Task.Run(() => new Bitmap(stream));
}
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-media is a skill published in the GitHub repository linuxdevel/Avalonia-skills (36 stars, last pushed 4mo ago), licensed MIT. It adds 59 tokens to every session and 2,778 once invoked, about $0.0003 per session on Opus 5. 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.

webgl-particle-galaxy
A real-time particle galaxy — tens of thousands of additive-blended GPU points spiraling around a bright core, their orbits solved entirely in the vertex shader (from glVertexID), so the whole cloud draws in one call. Rendered as a single self-contained index.html. Use when the brief asks for a "particle field"…
webgl-liquid-metal
A real-time liquid-metal shader — a domain-warped noise field shaded as molten chrome, with a sweeping specular highlight over an iridescent thin-film (cosine-palette) sheen. No textures. Rendered as a single self-contained index.html. Use when the brief asks for "liquid metal", "molten chrome", "iridescent"…

A self-contained WebGL2 hero: layered aurora light curtains warped over a night sky scattered with stars; move the cursor to sway the veil.
webgl-horizontal-parallax
A horizontal-scroll WebGL gallery (Three.js): frames glide sideways with lerp smoothing and each image parallaxes its texture (UV shift) by its position in the viewport.
