Coding Agent Series

Why Grep Beat Embeddings in Our SWE-Bench Agent (Lessons from Augment)

I hosted Colin Flaherty, previously a founding engineer at Augment and co-author of Meta's Cicero AI, to discuss autonomous coding agents and retrieval systems. This session explores how agentic approaches are transforming traditional RAG systems, what we can learn from state-of-the-art coding agents, and how these insights might apply to other domains.

Rethinking RAG Architecture for the Age of Agents - Beyang Liu (Sourcegraph)

I hosted a session with Beyang Liu, CTO of Sourcegraph, to explore how the evolution of AI models has fundamentally changed how we should approach building agent systems. This discussion revealed why many best practices from the chat LLM era are becoming obsolete, and how the architecture of effective agents requires rethinking context management, tool design, and model selection from first principles.
