OpenClaw Signals: The Fault-Tolerance Frontier

Tools

Dead-Letter Queue Semantics Overhaul

This PR redesigns how failed tasks are handled, moving from simple retries to configurable dead-letter queues with full context preservation. It's a critical step for building reliable production workflows that don't lose work.

Idempotency Key Propagation in Worker Pools

Ensures idempotency keys are correctly threaded through parallel worker contexts, preventing duplicate side effects from retried tasks. This fixes a subtle but painful correctness issue at scale.

RFC: Task Graph Visualization and Debugging

This proposal outlines a built-in way to visualize task execution flows and dependencies. For complex orchestrations, this kind of observability is what separates a toy from a production-ready system.

Analysis: Cascade Failure Scenarios in Large Clusters

A deep dive into how a single node failure can propagate through OpenClaw clusters. The analysis provides concrete mitigation patterns, essential reading for anyone operating beyond a single-node setup.

News

Enhanced Plugin Sandboxing Model

Tightens the security boundaries for third-party plugins by introducing capability-based access control. If you're running untrusted code, this limits blast radius and is non-negotiable for multi-tenant environments.

Dynamic Resource Quota Adjustments

Introduces API endpoints to adjust task queue resource limits on the fly without restarts. This is a huge win for operational flexibility and cost management during traffic spikes.
