When an agent breaks in production, observability hands you a gorgeous autopsy — every call, latency, and token, but not why it broke or how to fix it. The fix is a loop that runs itself: failure → approved patch → locked-in regression test. Opik is just the example; the point is the loop.

Upgrading OpenClaw keeps breaking your agent fleet? This developer's solution: spin up a separate Gateway as a 'family doctor' that does nothing but fix the main Gateway's agents. Been running it through multiple upgrades — rock solid.

Cognition ships Devin Autofix: review bot comments auto-trigger fixes → CI reruns → loop until clean. Humans only step in for architecture calls. Key insight: a single agent is a tool, but agent + reviewer loop is a system — and systems compound.
