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 | $0.00049 | $0.00939 |
| Opus 5 | $0.00024 | $0.00469 |
| Sonnet 5 | $0.00010 | $0.00188 |
| Haiku 4.5 | $0.00005 | $0.00094 |
Grade A, and why
neo-dotnet-mvc 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 12d 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.

.NET MVC Expert Skill
Trigger On
- The user requests to create, debug, refactor, or review ASP.NET Core MVC applications.
- The project contains
ViewsandControllersdirectories and inherits fromController(notControllerBase). - The target framework is .NET 6.0 (LTS) and above.
- There is a need to optimize Server-Side Rendering (SSR) performance or improve view organizational structure.
Workflow
- Perceive (Architecture Awareness):
- Check
.csprojto identifyTargetFramework. - Analyze
Views/Sharedto confirm existing configurations for layouts and partial views. - Identify whether Tag Helpers and static resource versioning are enabled.
- Check
- Reason (Planning Phase):
- Evaluate whether complex Partial Views need to be migrated to View Components.
- Determine whether custom Tag Helpers are needed to simplify UI logic.
- Choose an appropriate ViewModel organization method based on project scale.
- Act (Execution Phase):
- Write high-quality controllers and strongly-typed views.
- Implement data validation (Data Annotations) and integrate them into ViewModels.
- Configure and use Tag Helpers to ensure the semantic correctness of forms and links.
- Validate (Standard Validation):
- Validate whether page rendering conforms to the expected HTML structure.
- Check whether model validation correctly operates on both the frontend and backend.
- Ensure Antiforgery tokens are correctly applied to all state-modifying requests.
Feature Roadmap (.NET 6 - 10)
.NET 6 & 7 (Foundation)
- Tag Helpers: Declarative HTML attribute extensions.
- View Components: Logic-driven UI block modularization.
- Cache Tag Helper: Server-side view fragment caching.
- Nullable Views: Better Razor null safety support.
.NET 8 & 9 (Productivity)
- Blazor Integration: Hybrid development support for MVC and Blazor components.
- Antiforgery Improvements: Global anti-forgery automatic validation optimization.
- Keyed Services in Controllers: Finer-grained dependency injection support.
- Native AOT for MVC: Metadata compilation optimization tailored for AOT.
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.

neo-dotnet-mvc is a skill published in the GitHub repository Benknightdark/neo-skills (7 stars, last pushed 6d ago), licensed MIT. It adds 49 tokens to every session and 939 once invoked, about $0.0002 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 2026-08-31.
