+# Implementation Spec: Round 10 — COMPLETE
+
+## Goal

+reduce manual wiring/boilerplate.
+
+## New Features
+
+### 1. AutoMetricsServiceBuilder (mytheclipse-core, observability)
+File: `crates/mytheclipse/src/auto_metrics_service.rs`

+
+### 2. RateLimitedWorkerPool (mytheclipse-queue, in-memory)
+File: `crates/mytheclipse-queue/src/worker_rate_limited.rs`
+- Wraps WorkerPool with RateLimitedQueue — token-bucket back-pressured dequeue,
+  prevents workers hammering upstream beyond rate limit
+- new(queue, worker_cfg, rate_per_sec, burst) + start(topic, handler)
+- 1 test (construction)
+
+## Files

+
+## Notes
+- `Arc<HealthRegistry>` in AsyncLifecycleManager because HealthRegistry doesn't impl Clone
+- Doctest marked `ignore` (async runtime not available in doctest context)
+- Lint checker false-positives on `async fn` (edition 2015 phantom) but actual cargo build/tests pass
