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 | $0.00044 | $0.00504 |
| Opus 5 | $0.00022 | $0.00252 |
| Sonnet 5 | $0.00009 | $0.00101 |
| Haiku 4.5 | $0.00004 | $0.00050 |
Grade A, and why
aspnetcore-minimal-apis 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 9d 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.

ASP.NET Core Minimal APIs
Use When
- Building .NET 8+ minimal API services or BFF layers
- Teams want thin Program.cs with endpoint groups and filters
- Cross-stack skill
dotnet-aspnet-core-microservicesneeds .NET-specific implementation depth
Workflow
- Register services in DI (DbContext, handlers, auth).
- Group endpoints with MapGroup and route prefixes (/api/v1).
- Use typed request records and IResult/Results for responses.
- Add endpoint filters for validation, logging, and problem details.
- Configure JWT bearer or Entra ID; apply RequireAuthorization per route.
- Test with WebApplicationFactory and integration tests.
Required Checks
- CancellationToken forwarded to all async I/O
- ProblemDetails for errors — consistent with RFC 9457
- OpenAPI documents auth schemes and error responses
- No .Result or .Wait() on async calls in request path
Examples And Templates
See examples/ for side-by-side good vs bad patterns agents commonly get wrong.
See templates/ for copy-paste starters aligned with this skill.
Decision Framework
- Prefer minimal APIs for small services; MVC/controllers when view-heavy or complex model binding.
- Use IMediator (MediatR) when handlers grow — keep MapPost one-liners as entry only.
- Health checks at /health; readiness includes DB ping.
- Use IOptions for config — not static ConfigurationManager reads in handlers.
Common Rationalizations And Rebuttals
- "Minimal APIs are only for demos." -> Production-ready with filters, auth, and testing patterns.
- "One file is fine." -> Split endpoint groups by domain as service grows.
- "Exception middleware is enough." -> Validate at boundary; return typed validation problems.
Evidence Pack
- OpenAPI snapshot with security schemes
- Integration test output for authorized vs anonymous calls
- Endpoint filter unit test for validation failures
- Health/readiness probe configuration
Exit Criteria
- Endpoints are typed, authorized, and documented
- Async and cancellation used throughout request path
- Error responses match API contract
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.

aspnetcore-minimal-apis is a skill published in the GitHub repository vaquarkhan/Fullstack-development-agent-skills (2 stars, last pushed 4d ago), licensed MIT. It adds 44 tokens to every session and 504 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.
