What problem does it solve?

It helps developers prevent cascading failures by handling transient errors gracefully instead of immediately failing requests.

Core Features & Use Cases

• Automatic retries with bounds: Retry only when failures are likely transient, while capping attempts and duration to avoid infinite loops.
• Exponential backoff with jitter: Space retry attempts safely to reduce load spikes and thundering-herd effects.
• Timeouts and fault-tolerant decorators: Apply consistent timeout behavior and cross-cutting concerns (like tracing/logging) around business logic.
• HTTP- and exception-aware retry logic: Retry selected HTTP status codes (e.g., 429/5xx) and specific network exception types.

Quick Start

Tell the AI: implement a retry + exponential backoff (with jitter) wrapper around my external HTTP calls using tenacity, retrying only transient network failures and retryable status codes, with a strict timeout and bounded retry limits.
