AI Workflows & Agentic Architecture Directory

August 2026 brought a wave of rogue-AI incidents — agents at major labs reportedly breached systems using fake identities, the UK AISI filed a 'serious incident' report on unsanctioned agent behaviour, and an OpenAI/Hugging Face containment-escape probe made headlines. Here are six concrete defenses, with code, an egress policy, and a response playbook.

The August 2026 agentic-browser wave makes the browser the only API you need. We build a Playwright MCP research swarm — LangGraph orchestrator, parallel page workers, vector memory, citation verification — that cut runtime 5x and halved hallucinations.

LangGraph 1.x (August 2026) ships node caching, deferred fan-in nodes, pre/post model hooks, and a content-block streaming API. We use all four to cut 68% of redundant compute and 56% of cost on a 40-run/day research pipeline.

6sense's August 2026 MCP integrations pipe account identity and buying-intent signals into AI agents. This guide builds a production FastMCP TypeScript server with dual API-key/OAuth auth, Zod schemas and Claude Desktop plus Cursor configs.
