redb.Route.Llm.Abstractions

Contracts package for the redb.Route.Llm tool surface. Apache 2.0.

Holds the declarative types every redb.Route LLM tool author needs, without pulling the provider engine, HttpClient, or Anthropic/OpenAI SDK code.

What's in this package

Type Role
LlmToolCapability Tool metadata exposed to the model (name, description, input schema).
LlmToolSafety Governance metadata — side-effect, cost, caching, approval, claims.
ToolSideEffect, ToolCostClass, ToolCachingPolicy Enums used by LlmToolSafety.
ILlmToolDescriptor The contract a tool implements: capability + endpoint URI builder.
IToolDescriptorRegistry Registry of ILlmToolDescriptor resolved by tool name.
[ExposeAsLlmTool] Attribute that adorns handler classes / methods to declare their tool surface.

Why a separate package

  • The LLM engine (redb.Route.Llm) is heavy: HTTP transport, SSE parsers, Anthropic / OpenAI providers, governance, conversation persistence.
  • The contracts are tiny: a handful of POCOs, an interface, and an attribute.

A connector or third-party tool author who wants to declare an ILlmToolDescriptor can take a dependency on this package without inheriting the entire engine surface.

Dispatch model

ILlmToolDescriptor is declarative + URI-building, not self-executing. The engine in redb.Route.Llm resolves the descriptor, calls BuildEndpointUri(inputJson, parentExchange), then dispatches via IProducerTemplate.RequestBody(endpointUri, message). Every tool runs as a redb.Route exchange — gets the parent's transaction scope, headers, principal, and DI scope for free.

redb.Route.Llm.Tools

Batteries-included LLM tools for redb.Route.Llm. Reference implementations of common agent tools (HttpFetch, ShellExec, Fs, Calc) built directly on .NET BCL APIs — no redb.Route connector dependencies. Each tool is a route + descriptor pair registered via the .AsLlmTool(...) DSL. Optional package — host applications opt in by referencing it.
redb.Route.Llm

Industrial LLM connector for redb.Route ESB framework. Provider-agnostic agent engine, tool-loop with governance (budget, shadow, idempotency, approval), conversation persistence via redb-engine, native EIP integration. See doc/PLAN.md.
