USE FOR: Extending ASP.NET Core Web API with custom formatters, content negotiation, and media type handling using WebApiContrib.Core. Use when you need to serve or consume CSV, BSON, MessagePack, Protocol Buffers, or other non-JSON formats alongside JSON in the same API. DO NOT USE FOR: Building entire APIs from scratch (use ASP.NET Core minimal APIs or controllers), GraphQL endpoints (use Hot Chocolate), or gRPC services (use ASP.NET Core gRPC).

improve

Use when producing agent/LLM evals, synthetic simulation data, or self-improvement pipelines for prompts, code, skills, agents, harnesses, and workflows. Covers AgentEvals/AgentV, Agent Skills evals, ASSERT, GEPA, Trace, VISTA, Agent Lightning, SkillOpt, Simula-style data design, progressive disclosure, deterministic workspaces, and release evidence. USE FOR: eval creation, EVAL.yaml, AgentEvals, AgentV, evals.json, ASSERT, judge-traces, behavior taxonomy, judges, graders, rubrics, synthetic data, simulation data, Simula, QDC, source-grounded generation, prompt optimization, agent improvement, skill improvement, harness hardening, progressive disclosure, deterministic workflows, GEPA, Trace, VISTA, Agent Lightning, SkillOpt DO NOT USE FOR: ordinary unit/integration tests without AI quality criteria (use testing), refactoring without eval or trace feedback (use refactor), generic Agent Skills packaging without eval or improvement work (use agent-skills)

2026-06-09

Use when working with AI agent protocols, standards, interoperability specifications, evaluation contracts, synthetic simulation data, improvement pipelines, and agent steering workflows. Covers MCP, A2A, ACP, Agent Skills, AGENTS.md, ADL, Improve, x402, AP2, MCP Apps, cagent, and learn. USE FOR: agent protocol selection, comparing MCP vs A2A vs ACP, understanding agent standards ecosystem, choosing payment protocols, choosing eval standards, choosing improvement techniques, choosing synthetic data simulation techniques, steering from user feedback DO NOT USE FOR: specific protocol, eval, or improvement implementation details (use the sub-skills: mcp, a2a, acp, improve, learn, x402, etc.)

learn

Use when a user corrects, rejects, edits, or redirects an LLM/agent response and the correction should become a reusable reasoning strategy. Converts feedback into generalized learnings for ~/.agents/STEERING.md with linked RDF/Turtle evidence. USE FOR: user corrections, preference feedback, rejected agent behavior, reasoning strategy updates, steering file maintenance DO NOT USE FOR: storing task facts (use memory), ordinary skill authoring (use agent-skills), project instruction files unrelated to feedback (use agents-md)

WebApiContrib

Overview

WebApiContrib.Core is a community-driven collection of extensions for ASP.NET Core Web API that adds custom input/output formatters, content negotiation strategies, and utility middleware. The library provides formatters for CSV, BSON, MessagePack, Protocol Buffers, and plain text, enabling APIs to serve multiple content types through standard HTTP content negotiation (the header). WebApiContrib.Core integrates with the ASP.NET Core MVC formatter pipeline, allowing controllers and minimal APIs to return data in the format requested by the client without changing action method signatures. It also includes additional filters, model binders, and helper utilities.

using MessagePack; using Microsoft.AspNetCore.Mvc.Formatters; using Microsoft.Net.Http.Headers; namespace MyApp.Formatters; public class MessagePackOutputFormatter : OutputFormatter { private readonly MessagePackSerializerOptions _options; public MessagePackOutputFormatter() { _options = MessagePackSerializerOptions.Standard .WithCompression(MessagePackCompression.Lz4BlockArray); SupportedMediaTypes.Add(MediaTypeHeaderValue.Parse("application/x-msgpack")); SupportedMediaTypes.Add(MediaTypeHeaderValue.Parse("application/msgpack")); } protected override bool CanWriteType(Type? type) => type != null; public override async Task WriteResponseBodyAsync(OutputFormatterWriteContext context) { var response = context.HttpContext.Response; var bytes = MessagePackSerializer.Serialize( context.ObjectType!, context.Object, _options); response.ContentType = "application/x-msgpack"; response.ContentLength = bytes.Length; await response.Body.WriteAsync(bytes); } } public class MessagePackInputFormatter : InputFormatter { private readonly MessagePackSerializerOptions _options; public MessagePackInputFormatter() { _options = MessagePackSerializerOptions.Standard .WithCompression(MessagePackCompression.Lz4BlockArray); SupportedMediaTypes.Add(MediaTypeHeaderValue.Parse("application/x-msgpack")); SupportedMediaTypes.Add(MediaTypeHeaderValue.Parse("application/msgpack")); } public override async Task<InputFormatterResult> ReadRequestBodyAsync( InputFormatterContext context) { var request = context.HttpContext.Request; using var memoryStream = new MemoryStream(); await request.Body.CopyToAsync(memoryStream); memoryStream.Position = 0; var result = await MessagePackSerializer.DeserializeAsync( context.ModelType, memoryStream, _options); return await InputFormatterResult.SuccessAsync(result); } } // Registration builder.Services.AddControllers(options => { options.OutputFormatters.Add(new MessagePackOutputFormatter()); options.InputFormatters.Add(new MessagePackInputFormatter()); options.RespectBrowserAcceptHeader = true; options.ReturnHttpNotAcceptable = true; });
