orchardcore-openapi

orchardcore-openapi is a skill for Claude Code from CrestApps/CrestApps.AgentSkills. It costs 203 tokens per session (2,521 once invoked), scanned A, original, MIT.

A guide for Orchard Core 4's OpenAPI module, which generates machine-readable API descriptions and browser-based documentation through Swagger UI, ReDoc, and Scalar. OpenAPI is a standard way to describe how an API can be called.

In plain words
What is it for?
Use it to configure OpenAPI generation, documentation interfaces, access permissions, and PKCE sign-in for API testing.
Why use it?
It helps teams document and explore API endpoints while controlling who can view the documentation and schemas. It also covers sign-in for authenticated test requests and the option to allow anonymous schema access.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

orchardcore-openapi 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 yesterday.

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.

Document and Explore Orchard Core APIs

You are an Orchard Core expert. Generate configuration, recipes, and code for the OrchardCore.OpenApi module, which ships with Orchard Core 4.0.

Guidelines

  • OrchardCore.OpenApi generates the OpenAPI document (Swashbuckle at /swagger/v1/swagger.json, plus the ASP.NET Core /openapi/*.json document) for every enabled API endpoint.
  • The documentation UIs are separate sub-features that each depend on OrchardCore.OpenApi. A disabled UI returns 404.
  • Every documentation URL (/swagger, /redoc, /scalar, /openapi) requires an authenticated user with ViewOpenApiContent. Anonymous users are redirected to the admin login; authenticated users without the permission get 403.
  • The JSON schema endpoints also require ViewOpenApiContent (cookie or Api bearer token) unless Allow anonymous access to the API schema (AllowAnonymousSchemaAccess) is enabled. Unauthenticated schema requests get a 401 with a WWW-Authenticate header and a Problem Details body.
  • ManageOpenApi implies ViewOpenApiContent. Grant only ViewOpenApiContent to roles that should read the docs without changing settings. Both are granted to Administrator by default.
  • Orchard Core APIs authenticate with the Api scheme, which accepts bearer tokens only. Swagger UI and Scalar acquire a token silently (authorization code + PKCE, prompt=none in a hidden iframe) from the tenant's own OpenID server, using the admin cookie session. ReDoc is read-only and needs no token.
  • Run the OpenApiPkce recipe once per tenant to provision that silent sign-in. Client credentials and password grants are intentionally not supported by the browser UIs.
  • Tokens stay in memory, are attached only to same-origin requests whose path contains /api/, and a rejected token triggers one silent re-sign-in and retry.
  • All recipe JSON must be wrapped in the root { "steps": [...] } format.
  • All C# classes must use the sealed modifier, except View Models.
