We engineered this zero-bloat Cloudflare Workers / TypeScript blueprint to enforce bounded concurrency, deterministic exponential backoff with jitter, strict schema validation at the ingestion boundary, and structured JSON telemetry—ready to drop into production without weeks of plumbing.

"""AI Dev Tool: Async Token-Bucket Rate Limiter & Circuit Breaker (Python 3.12)
This module implements an asynchronous token-bucket rate limiter and circuit breaker.
The rate limiter ensures that the number of requests made to a service within a given time window
does not exceed a predefined threshold. The circuit breaker detects when a service is not responding
and prevents further requests from being made until the service is restored.
The architecture of this module is based on the token-bucket algorithm, where tokens are added to a bucket
at a constant rate. Each request consumes one token from the bucket. If the bucket is empty, the request
is blocked until a token is available.
The module uses bounded concurrency to prevent too many requests from being made concurrently.
This is achieved by using a semaphore to limit the number of concurrent requests.
To use this module, run the following command:
python -m ai_dev_tool_async_rate_limiter --help
This will display the available command-line options.
Configuration:
The module uses a configuration file to store the rate limiter and circuit breaker settings.
The configuration file is a JSON file that contains the following settings:
