+# Implementation Spec: Round 10 — COMPLETE
+
+## Goal
+Auto-integration + ergonomics: rate-limit workers, auto-metrics on service calls —
+reduce manual wiring/boilerplate.
+
+## New Features
+
+### 1. AutoMetricsServiceBuilder (mytheclipse-core, observability)
+File: `crates/mytheclipse/src/auto_metrics_service.rs`
+- Composes ServiceBuilder + MetricsCollector (+ MetricsBridge when resiliency)
+- `.run()` auto-records: calls_total counter (labelled by outcome ok/err/timeout/
+  circuit_open/rate_limited) + duration histogram; emits bridge when attached
+- Chainable .with_collector/.with_bridge/.with_builders
+- 1 test
+
+### 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
+- new: core/src/auto_metrics_service.rs, queue/src/worker_rate_limited.rs
+- core/lib.rs: +module+export AutoMetricsServiceBuilder
+- queue/lib.rs: +module+export RateLimitedWorkerPool (rewrote export block)
+
+Build: exit 0. Tests: 0 FAILED (86 core pass). Clippy: 0 new warnings.

-- core/lib.rs: pub use RunError, ServiceConfig from service_builder

+## Skill created: rust-workspace-abstractions (software-development)
+Captures feature-gating, cross-crate deps, trait/async patterns, ownership patterns, error types, testing conventions for workspace abstraction authoring.
