<?php declare(strict_types=1);
    public function pre(RequestInterface $request, array $options = []): CancellablePromiseInterface
    {
        if (!isset($options[UserAgentMiddleware::class][Options::STRATEGY])) {
            return resolve($request);
        }

        $strategy = $options[UserAgentMiddleware::class][Options::STRATEGY];

        if (!class_exists($strategy)) {
            return resolve($request);
        }

        if (!is_subclass_of($strategy, UserAgentStrategyInterface::class)) {

Due to PHP Bug #53727, is_subclass_of might return inconsistent results on some PHP versions if \ApiClients\Middleware\UserAgent\UserAgentStrategyInterface::class can be an interface. If so, you could instead use ReflectionClass::implementsInterface.

            return resolve($request);
        }

        /** @var UserAgentStrategyInterface $strategy */
        $strategy = new $strategy();

        return resolve(
            $request->withAddedHeader(
                'User-Agent',
                $strategy->determineUserAgent($request, $options[UserAgentMiddleware::class])
            )
        );
    }
