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 | $0.00099 | $0.01541 |
| Opus 5 | $0.00049 | $0.00771 |
| Sonnet 5 | $0.00020 | $0.00308 |
| Haiku 4.5 | $0.00010 | $0.00154 |
Grade A, and why
dotnet-api 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 5d 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.

dotnet-api
Overview
ASP.NET Core APIs, data access, backend services, security, and cloud-native patterns. This consolidated skill spans 32 topic areas. Load the appropriate companion file from references/ based on the routing table below.
Baseline dependency: references/minimal-apis.md defines the core ASP.NET Core Minimal API patterns (route groups, endpoint filters, TypedResults, parameter binding) that apply to most API development tasks. Load it by default when building HTTP endpoints.
Most-shared companion: references/architecture-patterns.md covers vertical slices, request pipelines, error handling, caching, and idempotency patterns used across nearly all ASP.NET Core projects.

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.
- 5d ago First seen · 72 lines · 99 tokens per session scan A e372706f4be0
dotnet-api is a skill published in the GitHub repository novotnyllc/dotnet-artisan (228 stars, last pushed 17d ago), licensed MIT. It adds 99 tokens to every session and 1,541 once invoked, about $0.0005 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 2026-08-30.
