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 | $0.00048 | $0.00755 |
| Opus 5 | $0.00024 | $0.00378 |
| Sonnet 5 | $0.00010 | $0.00151 |
| Haiku 4.5 | $0.00005 | $0.00076 |
Grade A, and why
animation-editor-browser-verify 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 3d 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 — 51 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Animation Editor — Browser Visual Verify
Use when the question is Browser/WASM-specific (boot, Browser host wiring, Debug automation bridge). Prefer Core.Tests + desktop Headless/DocScreenshots for command behavior and desktop UI — see animation-editor-testing.
Shared desktop drive scripts: AnimationEditor.Core.Demo.FeatureDemos (internal; InternalsVisibleTo tests/DocScreenshots only) — desktop only, not Browser shipping App.
When to add a Browser.Ui test
Add one only if Headless/desktop cannot catch it, e.g.:
- WASM cold start / sample load / canvas ready
- Browser-only host wiring (
BrowserHotkeys, Open Folder FS APIs, no Ctrl+D) - “Does the Debug automation bridge still reach real handlers on Browser?”
Do not port Core or [AvaloniaFact] suites here. Browser Playwright is slow (ephemeral ports, Debug host) and drives a different shell (BuildView, not MainWindow). Keep a small smoke set; grow only when a Browser-specific bug appears. Full “when / how” lives in tools/AnimationEditorAvalonia/tests/AnimationEditor.Browser.Ui/README.md.
Do not pollute shipping App code
Landmine: never commit ?demo= / FeatureDemos.TryRun wiring into Browser App.axaml.cs BuildView (or Desktop MainWindow). A query-param backdoor mutates undo state on any deployed build.
Default proof path:
- Core unit tests for labels/commands (
CommandDescriptionTests/BrowserUiDriveLabelTests). - Desktop History PNGs via DocScreenshots +
FeatureDemos.TryRun. - Optional Browser smoke: Playwright under
tests/AnimationEditor.Browser.Ui/— Debug__aeUiAutomationclicks byAutomationIdand dumps undo Descriptions. Runscripts/run-browser-ui-drive.ps1.
Landmine — no Playwright getByRole on Avalonia.Browser today: the canvas host does not expose control ARIA to the DOM (CDP AX tree ≈ page title). Keep AutomationProperties for desktop a11y + stable ids; Browser drive uses the Debug bridge, not DOM a11y.

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-browser-verify is a skill published in the GitHub repository vchelaru/FlatRedBall2 (14 stars, last pushed today), licensed MIT. It adds 48 tokens to every session and 755 once invoked, about $0.0002 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 2026-09-04.
