Building Swoole applications often fails in subtle ways—leaking state across requests, blocking inside coroutines, misusing runtime hooks, or mishandling graceful reloads—leading to hard-to-debug production incidents.
Use the swoole-expert skill to review your Swoole server code for coroutine safety, correct hook configuration, and graceful reload behavior.

Swoole long-running workers leak state when you rely on php-fpm behaviors like superglobals, session_start, or static variables. You must manage object lifetimes explicitly and avoid shared state across resident worker processes.
SWOOLE_HOOK_ALL enables runtime hooks that rewrite blocking PHP I/O operations into coroutine-safe asynchronous operations. Enabling it is a non-negotiable default to prevent blocking inside coroutines and ensure cooperative scheduling.
Swoole connection pooling requires per-coroutine connection ownership to prevent race conditions. You must enforce lifecycle rules that fetch and release connections within the coroutine boundary, avoiding shared state pitfalls specific to resident workers.
Swoole coroutines block when runtime hook flags are misconfigured or when executing CPU-bound tasks. You must use SWOOLE_HOOK_ALL to hook blocking I/O and apply concurrency primitives like Channels for safe cooperative scheduling.
php-fpm session_start does not work correctly with Swoole HTTP servers because resident worker processes share state across requests. You must manage session data explicitly within the coroutine container to avoid cross-request contamination.
Production Swoole graceful reload requires safe cleanup using defer to release resources within the coroutine container before the worker terminates. You must apply lifecycle rules to avoid dropping active TCP or WebSocket connections during reloads.
