/v1/messages request builder (cache_control breakpoints on the first 2 system blocks + last 2 messages, tool schema -> input_schema, extended thinking budget) and an SSE decoder built on eventsource-stream, mapping content_block_start/delta/stop and message_delta into our normalized LlmEvent stream (text, thinking+signature, streamed tool-call JSON accumulated and parsed at content_block_stop, usage merged from message_start + message_delta). AnthropicProvider wires this to reqwest with x-api-key/anthropic-version/anthropic-beta headers and classifies HTTP errors into RateLimited/Auth/Overloaded/Http. ProviderRegistry resolves "provider/model" strings. Also tightened processor::process_step's cancellation: the event loop now selects the stream poll against ctx.cancel instead of only checking at the top of the loop, so a blocked provider stream is actually interrupted by abort (matches docs/02-engine.md's cancellation semantics). 127 tests passing, clippy clean.
ai-harness
A terminal AI coding harness in Rust — ratatui TUI, GitHub Copilot / OpenAI / Anthropic providers, and fully config-driven multi-agent orchestration inspired by opencode and oh-my-opencode-slim.
Status: design phase. The full design lives in docs/.
