Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00024 | $0.00243 |
| Opus 5 | $0.00012 | $0.00121 |
| Sonnet 5 | $0.00005 | $0.00049 |
| Haiku 4.5 | $0.00002 | $0.00024 |
Grade A, and why
aspnet-core 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.
What it actually says
ASP.NET Core
Cross-platform, high-performance framework for building modern web apps.
When to Use
- High-performance APIs (one of the fastest benchmarks)
- Enterprise applications
- Microservices
- Real-time apps (SignalR)
Quick Start
var builder = WebApplication.CreateBuilder(args);
var app = builder.Build();
app.MapGet("/", () => "Hello World!");
app.Run();
Core Concepts
Middleware Pipeline
Request processing pipeline composed of delegates.
Dependency Injection
Built-in DI container, a core citizen of the framework.
Kestrel
Cross-platform web server for ASP.NET Core.
Best Practices
Do:
- Use the built-in DI
- Use asynchronous controllers (
async Task<IActionResult>) - Use Environment Variables for config settings
Don't:
- Block asynchronous code (
.Resultor.Wait()) - Store large objects in Session state

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.

aspnet-core is a skill published in the GitHub repository G1Joshi/Agent-Skills (12 stars, last pushed 6mo ago), licensed MIT. It adds 24 tokens to every session and 243 once invoked, about $0.0001 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 2026-09-03.
