One Buggy Agent Can Take Down Shared Infrastructure: Rate Limiting as First Defense
alex_verem · x · 2026-08-20
The thread discusses "harness engineering" around AI agents: every request hits a rate limiter before reaching your API — within the limit it returns 200 OK; over the limit it's blocked with a 429 and the client retries after a wait. That single checkpoint protects both uptime and cost. Rate limiting is just one layer of the harness around an agent; the linked article argues the best solo AI setup makes the worst team setup and covers how teams should apply harnesses systematically.
