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 | $0.00643 | $0.00643 |
| Opus 5.5 | $0.00257 | $0.00257 |
| Sonnet 5.5 | $0.00129 | $0.00129 |
| Haiku 4.5 | $0.00064 | $0.00064 |
Grade A, and why
aspnetcore-realworld-example-app AGENTS.md 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.

Repository Guidance
Overview
- The application is an ASP.NET Core 10 API implementing the RealWorld specification.
src/Conduitcontains the web application and its feature-oriented vertical slices.tests/Conduit.IntegrationTestscontains xUnit integration tests using scoped SQLite contexts and HTTP tests using WebApplicationFactory. Focused authentication tests also use EF Core InMemory.buildcontains the Bullseye build targets used by CI.realworldis a vendored git submodule containing the upstream API specification tests. Do not edit it unless the task explicitly targets the submodule.
Toolchain
- Use the .NET SDK version specified in
global.json(10.0.403, withlatestFeatureroll-forward) and targetnet10.0. - Package versions are managed centrally in
Directory.Packages.props. - Restore packages with lock files enabled. Restore updates to
packages.lock.jsonfiles should be included when dependencies change. - The build enforces locked restore. CI passes
--check-formatto the build runner to check formatting without rewriting files. - Nullable reference types, recommended analyzers, code-style checks, and warnings-as-errors are enabled in
Directory.Build.props. - CSharpier
1.3.0is the repository formatter. The repository uses four-space indentation, file-scoped namespaces,var, explicit accessibility modifiers, and sortedSystemusings.
Validation
Run the standard validation target after code changes:
dotnet run --project build/build.csproj -- test
The target formats the repository, builds the solution in Release mode, and runs all test projects. To format without building, run:
dotnet run --project build/build.csproj -- format
The CI-equivalent build, test, and publish pipeline is:
dotnet run --project build/build.csproj
Run the application locally with make run-local. The API is available at http://localhost:5050, and Swagger is available at /swagger.
The optional RealWorld API suites require the realworld submodule plus Hurl or Bun/Bruno:
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.
