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 | $0.01913 |
| Opus 5 | $0.00000 | $0.00957 |
| Sonnet 5 | $0.00000 | $0.00383 |
| Haiku 4.5 | $0.00000 | $0.00191 |
Grade A, and why
animation-editor-screenshots 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 4d 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 — 52 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Animation Editor — Documentation Screenshots
Headless PNG capture of the Animation Editor's UI, for illustrating documentation pages (Timing, Offsets, Collision, etc.) — not for verifying behavior. For correctness tests, use animation-editor-testing. For WASM browser smoke (not a Core/App mirror), see animation-editor-browser-verify. The DocScreenshots project shares plumbing with App.Tests (TestServices, CreateMainWindow, [AvaloniaFact]) but serves a different purpose — keep scenario code in the project matching its purpose.
Where, and why it's a separate project
tools/AnimationEditorAvalonia/tests/AnimationEditor.DocScreenshots/ — a separate headless project from AnimationEditor.App.Tests, not a folder inside it. Full rationale in tools/AnimationEditorAvalonia/docs/DOC_SCREENSHOT_HARNESS_DECISION.md.
Landmine — it must stay separate. Real pixel capture needs AvaloniaHeadlessPlatformOptions.UseHeadlessDrawing = false (see this project's TestAppBuilder.cs), set at the assembly level. AnimationEditor.App.Tests defaults that to true (a no-op drawing recorder, for speed) across its ~90 files, none of which need real pixels. Moving screenshot code into that project, or flipping its default, would either silently produce blank PNGs there or slow down the whole correctness suite.
Capturing
ScreenshotCapture.Capture(visual, outputPath) — pass a Window/dialog (TopLevel) for full chrome, or any Control (e.g. window.FindControl<Control>("AnimTree")) to crop to just that control's bounds. Built on TopLevel.CaptureRenderedFrame(), not a hand-rolled RenderTargetBitmap.Render(visual) — the latter silently writes an empty PNG under headless (see the decision doc).
Default to capturing the whole window, not a cropped control. A screenshot showing only one panel strips the viewer's frame of reference for where that panel sits in the app. Crop to a specific control only when the user explicitly asks to see just that panel.
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.

animation-editor-screenshots is a skill published in the GitHub repository vchelaru/FlatRedBall2 (14 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,913 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 2026-09-04.
