OpenClaw Signals: Parallel Execution, Hook Registries, and the Observability Push

Tools

Concurrent Task Execution Engine

This PR introduces parallel task execution within single workers, letting you batch independent operations without spinning up extra processes. For builders running I/O-heavy workloads, this is a real throughput unlock.

Structured Metrics Emission

Proposes standardizing metric output formats for Prometheus and OpenTelemetry compatibility. Observability is table stakes for production use, and this gets OpenClaw closer to plug-and-play monitoring.

Dependency Graph Caching Layer

Adds caching to the dependency resolver to skip redundant graph traversals on repeated runs. Small change, big speedup for projects with large dependency trees.

Analysis

Modular Hook Registry Proposal

A community RFC to decouple lifecycle hooks into a standalone registry, making it easier to compose custom behaviors without forking core. If you're building plugins, this directly impacts your extension strategy.

Exponential Backoff vs Jitter Debate

Active discussion on whether the retry mechanism should use pure exponential backoff or add jitter to prevent thundering herd problems. Worth watching if you run OpenClaw at scale with flaky downstream services.
