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 | $0.00037 | $0.01692 |
| Opus 5.5 | $0.00015 | $0.00677 |
| Sonnet 5.5 | $0.00007 | $0.00338 |
| Haiku 4.5 | $0.00004 | $0.00169 |
Grade A, and why
dotnet-blazor 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 1mo 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.
This is a copy
86% identical to blazor — 14 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 246 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Blazor
Trigger On
- building interactive web UIs with C# instead of JavaScript
- choosing between Server, WebAssembly, or Auto render modes
- designing component hierarchies and state management
- handling prerendering and hydration
- integrating with JavaScript when necessary

Render Modes (.NET 8+)
| Mode | Where It Runs | Best For |
|---|---|---|
Static |
Server (no interactivity) | SEO pages, marketing content |
InteractiveServer |
Server via SignalR | Real-time apps, thin clients |
InteractiveWebAssembly |
Browser via WASM | Offline-capable, client-heavy |
InteractiveAuto |
Server first, then WASM | Best of both worlds |
Applying Render Modes
@* Per-component *@
@rendermode InteractiveServer
@* Or in App.razor for global *@
<Routes @rendermode="InteractiveAuto" />
InteractiveAuto Architecture
First Request:
Browser → Server (Interactive Server) → Fast response
Subsequent Requests:
Browser → WASM (downloaded in background) → No server needed
Workflow
- Choose render mode based on requirements:
- Need SEO? Start with Static or prerendering
- Need real-time? Use InteractiveServer
- Need offline? Use InteractiveWebAssembly
- Want both? Use InteractiveAuto
What ships with it
3 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.

dotnet-blazor is a skill published in the GitHub repository managedcode/PrompterOne (45 stars, last pushed 5mo ago), licensed MIT. It adds 37 tokens to every session and 1,692 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 86% identical to blazor, differing in 14 lines, and is treated as a copy.
