Harrison Chase
Brought the framework world to files-as-substrate
In "Your harness, your memory" (Apr 2026) and Deep Agents, Chase made the agent's harness and its filesystem the load-bearing primitives — the agent works against files in a workspace, not just a context window — and on the Sequoia podcast argued context engineering, not the model, is the moat. The incumbent framework is converging on files-as-substrate from the opposite direction; Tropo governs them.
