Class AnthropicProvider

java.lang.Object

ai.doctruth.AnthropicProvider

All Implemented Interfaces:

LlmProvider

public non-sealed class AnthropicProvider
extends Object
implements LlmProvider

Anthropic Messages API provider. Hand-rolled JDK-HttpClient-backed implementation per ADR 0003 — no Anthropic SDK on the classpath. Vendor wire types are confined to ai.doctruth.internal.providers.anthropic and never appear in this class's public surface.

non-sealed so that test code (and advanced users) can anonymously subclass to supply canned responses or wrap behaviour. Public API is thread-safe: the underlying AnthropicHttpClient is stateless and shares one HttpClient.

Since:

0.1.0
