defect-core 0.1.0-alpha.6

Foundational shared types for defect: error, LLM protocol types, HTTP client trait, and tool schema. Zero dependency on the agent runtime, so provider/transport crates (defect-llm, defect-http) can depend on it without pulling in the session/turn machinery.

//! Tool schema — the wire-facing description of a tool's parameters.
//!
//! This is the minimal, self-contained piece of the tool layer that providers need:
//! `defect-llm` serializes [`ToolSchema`] into provider wire JSON. The full tool trait,
//! `ToolContext`, and runtime plumbing live in `defect-agent::tool` (they depend on the
//! session runtime and so cannot live here).

use serde::{Deserialize, Serialize};

/// A tool's wire-facing schema: name, description, and a JSON Schema for its parameters.
///
/// Providers don't hold `dyn Tool`; they serialize schemas into wire JSON.
