When Your "New Teammate" Hallucinates: Observability as the Safety Net for AI Code
summary
Argues that observability must be baked into AI-generated code by default and shows a working feedback loop: an agent uses repo skills and a pipeline skill to plan, deploy (AWS Lambda), run a load test (336 requests in 90s), pull traces/metrics via DDCTL/API, diagnose issues (5s latencies, 502s, missing pagination), patch code (adds semaphores, spans, structured logging), redeploy and iterate — one session ran for almost 12 hours and continually improved behavior.
