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 | $0.00041 | $0.00777 |
| Opus 5 | $0.00020 | $0.00388 |
| Sonnet 5 | $0.00008 | $0.00155 |
| Haiku 4.5 | $0.00004 | $0.00078 |
Grade A, and why
using-mewui-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 10d 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.

StackPanel
new StackPanel()
.Orientation(Orientation.Vertical) // or .Horizontal(), .Vertical()
.Spacing(8)
.Children(
new Label().Text("First"),
new Label().Text("Second"),
new Button().Content("Action")
)
Grid
new Grid()
.Rows("Auto,*,Auto") // Auto, Star(*), Pixel(100)
.Columns("200,*")
.Spacing(8) // Note: single Spacing property for both rows and columns
.Children(
new Label().Text("Header").Row(0).ColumnSpan(2),
new ListBox().Row(1).Column(0),
new ContentControl().Row(1).Column(1),
new Button().Content("OK").Row(2).Column(1)
)
// Convenience: .GridPosition(row, column) or .GridPosition(row, col, rowSpan, colSpan)
Row/Column definitions: "Auto" (content), "*" (proportional), "2*" (2x proportional), "100" (pixels)
Canvas
new Canvas()
.Children(
new Rectangle().CanvasLeft(10).CanvasTop(10).Width(50).Height(50),
new Rectangle().CanvasRight(10).CanvasBottom(10).Width(50).Height(50)
)
// Convenience: .CanvasPosition(left, top)
Rules: Left > Right, Top > Bottom. Both set = stretch.
DockPanel
new DockPanel()
.LastChildFill(true)
.Children(
new Menu().DockTo(Dock.Top), // Note: .DockTo() not .Dock()
new StatusBar().DockTo(Dock.Bottom),
new TreeView().DockTo(Dock.Left).Width(200),
new ContentArea() // Fills remaining space
)
// Convenience methods: .DockTop(), .DockBottom(), .DockLeft(), .DockRight()
WrapPanel
new WrapPanel()
.Orientation(Orientation.Horizontal)
.Spacing(8) // Note: single Spacing property for all gaps
.ItemWidth(100).ItemHeight(100) // Optional fixed size
.Children(tag1, tag2, tag3, tag4)
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
