How to generate mergeable code with a context engine
Summary
Peter Werry's session centers on a concrete failure mode for coding agents: they can produce compilable code while still missing the project-specific relationships, conventions, ownership boundaries, and review expectations that make code mergeable. The connected Unblocked video and extracted slides frame the answer as a context engine rather than a larger prompt, bigger context window, or pile of disconnected MCP tools. The core idea is to assemble task-specific engineering context from a relational understanding of the codebase and team workflow, so agents receive the information that matters for the current change instead of broad, expensive, and noisy context dumps.
The talk fits the World's Fair software-factories theme because it treats AI coding as a production system problem: reducing token waste, review churn, and inconsistent outputs by improving the inputs and workflow around agents. Werry's perspective comes from Unblocked's work on context engines for engineering teams, where the emphasis is on helping agents understand how a system actually works before they generate code. The related public AI Engineer video is supporting context rather than a confirmed recording of this exact session, but it points to the same thesis: mergeable-by-default code requires structured, workflow-aware context.

Official Description
Your agents are fast, capable, and completely context-blind. They generate code that compiles but
doesn't reflect how your system actually works. You're likely already seeing the impact: ballooning
token costs, longer review cycles, and inconsistent outputs. More MCPs, rules, and bigger context
windows give agents access to information, but not understanding. In this session, we dissect how
teams pulling ahead use a context engine to give agents exactly what they need for the task at hand.
Includes a short demo showing the workflows a context engine can augment.
