Crate rig_agent 

Rig’s classic agent runtime.

This crate owns the mature builder, run state machine, typed hook system, contextual tool registry, memory orchestration, extraction, and shared blocking/streaming driver. Portable provider, message, tool, and storage contracts remain in rig_core and are reachable here through the explicit core namespace; this crate’s root deliberately exports only runtime-owned items. The comprehensive end-user facade is the root rig crate.

Target support

Native targets are fully supported. wasm32-unknown-unknown (browser) is supported with no feature flags to set — the relaxed async bounds follow from the target alone.

The rmcp feature is unavailable on wasm: rmcp’s ClientHandler requires Send + Sync unconditionally, which this crate’s wasm tool registry cannot satisfy, so asking for it there raises a targeted compile_error!. WASI (wasm32-wasip1/wasip2) is not supported: the dependency graph does not build for it. See the crate README for the full matrix and the reasoning.

Attribute Macros

rig_toolderive

A procedural macro that transforms a function into a portable rig_core::tool::PortableTool, or into the classic contextual rig::tool::Tool when the function accepts classic runtime context.

tool_macroderive

A procedural macro that transforms a function into a portable rig_core::tool::PortableTool, or into the classic contextual rig::tool::Tool when the function accepts classic runtime context.
