fix(sdk): tune rate limiter for fail-fast behavior#265
Merged
Conversation
Reduce exponential backoff aggressiveness to prevent 2+ hour workflow runtimes when using rate-limited providers like OpenRouter. The previous defaults (20 retries, 300s max delay, 300s circuit breaker) caused cascading backoff that compounded across parallel agents. New defaults: 5 retries, 0.5s base delay, 30s max delay, circuit breaker threshold 5 with 30s timeout. Max theoretical wait per call drops from ~100 minutes to ~2.5 minutes. Changes: - Python StatelessRateLimiter: max_retries 20→5, base_delay 1.0→0.5, max_delay 300→30, circuit_breaker_threshold 10→5, timeout 300→30 - TypeScript StatelessRateLimiter: identical parameter changes - AIConfig: updated Field defaults to match rate limiter - Added functional tests validating new defaults and max wait bounds Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
