AI Agent Harness Engineering Security Monitoring Automation Development OpenClaw routing from internet channels through the resident Gateway, deterministic bindings and session keys into per-agent enclaves, device nodes and external side effects n8n's Deterministic Exoskeleton: Why Queues and Workers Do Not Guarantee Exactly-Once Side Effects https://cubxxw.com/ai-agent/posts/agent-system-design-n8n/ Fri, 07 Aug 2026 17:25:00 +0800 Fri, 07 Aug 2026 17:25:00 +0800 熊鑫伟 (Xinwei Xiong) https://cubxxw.com/ai-agent/posts/agent-system-design-n8n/ Trace n8n 2.33.6 across Redis queues, workers and Postgres to see why scaling workflow throughput does not guarantee exactly-once effects in external systems. AI Agent Automation Harness Engineering Monitoring Security Development The n8n deterministic workflow spine, the constrained Agent spur, human and idempotency gates, external receipt reconciliation, and the Redis worker Postgres queue-mode yard Pi by Subtraction: What the Minimal Agent Kernel Keeps and Who Takes Responsibility https://cubxxw.com/ai-agent/posts/agent-system-design-pi/ Fri, 07 Aug 2026 16:40:00 +0800 Fri, 07 Aug 2026 16:40:00 +0800 熊鑫伟 (Xinwei Xiong) https://cubxxw.com/ai-agent/posts/agent-system-design-pi/ Trace Pi v0.84.1's agent loop, default tools and JSONL sessions to see what a minimal kernel keeps and who takes over security, recovery and workflow decisions. AI Agent Harness Engineering Open Source Development Security Context Engineering The Pi minimal agent kernel, the detachable extension rail, provider and host OS trust boundaries, and the JSONL session tree below
