//! Provider-agnostic, always-on LLM agent harness for Autumn.
//!
//! `autumn-plugin-agent` equips an Autumn app with tool-calling agents that
//! speak to OpenAI-compatible endpoints (OpenAI, Ollama, vLLM)
//! or the Anthropic Messages API — no heavyweight LLM SDK required.
//!
//! Beyond one-shot runs, the crate has the primitives always-on agents
//! share: persisted sessions with compaction, bounded memory, skills,
//! approval gates with resumable state, lifecycle hooks, a loop guard,
//! heartbeats on Autumn's scheduler, agent-scheduled follow-ups, and a
//! delivery channel.
//!
//! # Quick start
//!
//! ```rust,ignore
//! use autumn_plugin_agent::plugin::{AgentHandle, AgentPlugin};
//! use autumn_plugin_agent::{FnTool, AgentError};
//! use autumn_web::prelude::*;
//! use std::sync::Arc;
//!
//! async fn get_weather(input: serde_json::Value) -> Result<serde_json::Value, AgentError> {
//!     Ok(serde_json::json!({"temp_f": 72}))
//! }
//!
//! #[autumn_web::main]
//! async fn main() {
//!     let weather = FnTool::new(
//!         "get_weather",
//!         "Current weather for a city.",
//!         serde_json::json!({"type": "object",
//!             "properties": {"city": {"type": "string"}},
//!             "required": ["city"]}),
//!         get_weather,
//!     )
//!     .shared();
//!
//!     autumn_web::app()
//!         .plugin(AgentPlugin::new().tool(Arc::clone(&weather)))
//!         .run()
//!         .await;
//! }
//! ```
//!
//! ```toml
//! # autumn.toml
//! [agent]
//! provider = "openai-compatible"
//! model = "gpt-4o-mini"
//! ```
//!
//! ```sh
//! export AGENT_API_KEY="sk-..."
//! ```
//!
