Letta Code Lets Agents Modify Their Own Harness
dl_weekly · x · 2026-07-12
Letta has launched Mods for Letta Code, enabling agents to modify their own harness code rather than merely "learning" within the context.
This update includes a built-in learn / generate-env workflow, indicating a focus on creating a closed loop across the agent's runtime environment, code structure, and learning process, rather than just executing single calls.
