WTF Is the Context Layer? The Missing Infrastructure for Production Agents — Prukalpa Sankar
Jul 14, 2026 · 20:54
Prukalpa Sankar, founder of Atlan, argues that the missing infrastructure for production AI agents is a 'context layer' that encodes business knowledge, expertise, and norms into machine-usable form. She describes how her team built 300 skills and 40 agents but hit problems like context sprawl, dependency management, and skill quality. Sankar proposes a context layer with versioning, lifecycle management, and compounding learning loops from agent traces, enabling teams to share and maintain business context like code. She concludes that context is both king and intellectual property, differentiating companies when models and intelligence are commoditized.

Why your agents need decision traces, not just documents — Zach Blumenfeld, Neo4j
May 29, 2026 · 20:12
Zach Blumenfeld from Neo4j argues that context graphs—a graph-based layer storing decision traces, precedence, and causal chains—extend standard RAG to make AI agents more accurate and explainable. A financial analyst agent, for example, can reject or accept a request by retrieving past decision traces and structurally similar precedents via graph embeddings, not just semantic similarity. Neo4j's one-command tool `uvx create-context-graph` scaffolds a full-stack app with backend, frontend, demo data, and MCP server, supporting 22 built-in domains or custom ontology generation. The underlying `neo4j-agent-memory` package handles entity extraction through a spaCy-to-GLiNER-to-LLM pipeline with deduplication and integrates with pydantic AI, LangGraph, Crew, Google ADK, and others. The episode also covers data connectors for GitHub, Notion, Jira, and Slack, and the ability to store and query decision traces with timestamps, though automated trace quality evaluation is still evolving.

The Future of MCP — David Soria Parra, Anthropic
Apr 19, 2026 · 18:46
David Soria Parra from Anthropic argues that MCP (Model Context Protocol) is the key to connecting agents to tools and data in production, with 110 million monthly downloads—outpacing React's growth at the same stage. He lays out a 2026 connectivity stack combining Skills, MCP, and CLI/Computer Use, each suited for different needs, and emphasizes that best agents will use all three seamlessly. To improve client harnesses, he introduces Progressive Discovery—deferring tool loading via Tool Search to reduce context usage—and Programmatic Tool Calling, where models write scripts to compose tool outputs efficiently. Upcoming MCP protocol improvements include stateless transport (with Google) for easier scaling, async agent-to-agent tasks, enterprise features like Cross App Access and Server Discovery via well-known URLs, and a Skills-over-MCP extension for shipping usage instructions with servers. He calls for community feedback on these directions.
