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 | $0.00079 | $0.01150 |
| Opus 5.5 | $0.00032 | $0.00460 |
| Sonnet 5.5 | $0.00016 | $0.00230 |
| Haiku 4.5 | $0.00008 | $0.00115 |
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 2mo 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
100% identical to aspnet-core — 0 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.

ASP.NET Core
Overview
Choose the right ASP.NET Core application model, compose the host and request pipeline correctly, and implement features in the framework style Microsoft documents today.
Load the smallest set of references that fits the task. Do not load every reference by default.
Workflow
- Confirm the target framework, SDK, and current app model.
- Open references/stack-selection.md first for new apps or major refactors.
- Open references/program-and-pipeline.md next for
Program.cs, DI, configuration, middleware, routing, logging, and static assets. - Open exactly one primary app-model reference:
- Add cross-cutting references only as needed:
- Open references/versioning-and-upgrades.md before introducing new platform APIs into an older solution or when migrating between major versions.
- Use references/source-map.md when you need the Microsoft Learn section that corresponds to a task not already covered by the focused references.
Default Operating Assumptions
- Prefer the latest stable ASP.NET Core and .NET unless the repository or user request pins an older target.
- As of March 2026, prefer .NET 10 / ASP.NET Core 10 for new production work. Treat ASP.NET Core 11 as preview unless the user explicitly asks for preview features.
- Prefer
WebApplicationBuilderandWebApplication. Avoid olderStartupandWebHostpatterns unless the codebase already uses them or the task is migration. - Prefer built-in DI, options/configuration, logging, ProblemDetails, OpenAPI, health checks, rate limiting, output caching, and Identity before adding third-party infrastructure.
- Keep feature slices cohesive so the page, component, endpoint, controller, validation, service, data access, and tests are easy to trace.
- Respect the existing app model. Do not rewrite Razor Pages to MVC or controllers to Minimal APIs without a clear reason.
What ships with it
16 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.

aspnet-core is a skill published in the GitHub repository cass-2003/local-workflow-skill (12 stars, last pushed 3mo ago), licensed MIT. It adds 79 tokens to every session and 1,150 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to aspnet-core, differing in 0 lines, and is treated as a copy.
