blazor

blazor is a skill for Claude Code, Codex from G1Joshi/Agent-Skills. It costs 19 tokens per session (299 once invoked), scanned A, original, MIT.

A .NET framework for building web interfaces in C# instead of JavaScript, either on the server or in the browser.

In plain words
What is it for?
Use it to create interactive web applications, server-rendered sites, or browser applications compiled to WebAssembly.
Why use it?
It lets .NET teams share code between the frontend and backend and build internal web tools with one main language.

Token cost

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.

Security

Grade A, and why

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 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.

What it actually says

Blazor

Blazor allows writing web UIs in C# instead of JavaScript. .NET 9 (2024/2025) brings unified rendering modes (Server, WebAssembly, Auto).

When to Use

  • .NET Shops: Sharing code (Models/DTOs) between Backend and Frontend.
  • Internal Apps: Rapid development for enterprise tools.
  • WebAssembly: Running compiled C# in the browser.

Core Concepts

Blazor Server

UI logic runs on server, updates sent via SignalR. Low latency, requires connection.

Blazor WebAssembly

Runs client-side (DLLs downloaded). Offline support.

Interactive Components

Razor syntax (@code { ... }) combining HTML and C#.

Best Practices (2025)

Do:

  • Use Auto mode: Load fast (Server), then switch to WASM (Client) in background.
  • Use QuickGrid: High performance data grid component.
  • Use Component Libraries: MudBlazor/Radzen for material UI.

Don't:

  • Don't block the UI thread: Use await for long implementations.

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.
