-//! Metrics and Telemetry Module
-//!
-//! Provides comprehensive metrics and telemetry for tracking agent execution,
-//! including execution time, latency percentiles, token usage, tool success/failure rates,
-//! memory and CPU utilization, workflow step timing, and custom business metrics.
-//!
-//! # Architecture
-//!
-//! The module is structured around three concepts:
-//!
-//! 1. **Metric data types** — lightweight structs that capture counters, timings, and gauges
-//!    for agents, tools, workflows, routing decisions, model pool lifecycle, circuit breakers,
-//!    scheduler admission, and retries.
-//! 2. **`MetricsBackend` trait** — a pluggable sink so that callers can forward metrics to
-//!    Prometheus, OpenTelemetry, or any custom backend.
-//! 3. **`MetricsCollector`** — an in-memory, async-safe default implementation that stores
-//!    metrics behind `tokio::sync::RwLock` maps.
-//!
-//! # Example
-//!
-//! ```rust,ignore
-//! use mofa_foundation::metrics::{MetricsCollector, TokenUsage};
-//! use std::time::Duration;
-//!
-//! #[tokio::main]
-//! async fn main() {
-//!     let collector = MetricsCollector::new();
-//!
-//!     collector.record_agent_execution(
-//!         "agent-1",
-//!         Duration::from_millis(120),

+//! Metrics and Telemetry Module
+//!
+//! Provides comprehensive metrics and telemetry for tracking agent execution,
+//! including execution time, latency percentiles, token usage, tool success/failure rates,
+//! memory and CPU utilization, workflow step timing, and custom business metrics.
+//!
+//! # Architecture
+//!
+//! The module is structured around three concepts:
+//!
+//! 1. **Metric data types** — lightweight structs that capture counters, timings, and gauges
+//!    for agents, tools, workflows, routing decisions, model pool lifecycle, circuit breakers,
+//!    scheduler admission, and retries.
+//! 2. **`MetricsBackend` trait** — a pluggable sink so that callers can forward metrics to
+//!    Prometheus, OpenTelemetry, or any custom backend.
+//! 3. **`MetricsCollector`** — an in-memory, async-safe default implementation that stores
+//!    metrics behind `tokio::sync::RwLock` maps.
+//!
+//! # Example
+//!
+//! ```rust,ignore
+//! use mofa_foundation::metrics::{MetricsCollector, TokenUsage};
+//! use std::time::Duration;
+//!
+//! #[tokio::main]
+//! async fn main() {
+//!     let collector = MetricsCollector::new();
+//!
+//!     collector.record_agent_execution(
+//!         "agent-1",
+//!         Duration::from_millis(120),
+//!         true,
+//!         Some(TokenUsage {
+//!             prompt_tokens: 100,
+//!             completion_tokens: 50,
+//!             total_tokens: 150,
+//!             cost_estimate: 0.002,
+//!         }),
+//!     ).await;
+//!
+//!     let metrics = collector.get_agent_metrics().await;
+//!     println!("Agent executions: {}", metrics[0].total_executions);
+//! }
