Martin Casado hails 'best systems talk on agent harnesses'; dev shares lessons

a16z's Martin Casado called a talk the best systems-level treatment of agent harnesses and what self-improvement means under the bitter lesson. Developer blixt replied that it echoes his Elixir project "karna" for instant self-modification — which he abandoned after realizing it was a systems thinker's dream misaligned with how competitive harnesses co-evolve. His diagram lays out a four-layer harness: a hardened Guardian layer (health, rollbacks, kill/restart authority), a non-blocking human interface with triage, a persistent operator agent on SQLite with progressive skill disclosure, and disposable task subagents with context compression and resource locking.
