Generate PSR Component

Generate PHP-FIG compliant PSR implementations with tests.

Input Parsing

Parse $ARGUMENTS to extract PSR number, component name, and optional meta-instructions:

Format: <psr-number> <ComponentName> [-- <meta-instructions>]

Examples:
- /acc:generate-psr psr-3 FileLogger
- /acc:generate-psr psr-15 AuthMiddleware
- /acc:generate-psr psr-6 RedisCache -- with TTL support
- /acc:generate-psr psr-7 -- generate full HTTP stack

Parsing rules:

1. First part = PSR number (required: psr-3, psr-6, psr-7, etc.)
2. Second part = Component name (optional for some PSRs)
3. After -- = meta-instructions (optional customizations)

Supported PSRs

PSR	Name	Components Generated
psr-3	Logger Interface	LoggerInterface, AbstractLogger, LogLevel
psr-6	Caching Interface	CacheItemPoolInterface, CacheItemInterface
psr-7	HTTP Message	Request, Response, Uri, Stream, ServerRequest
psr-11	Container Interface	ContainerInterface, NotFoundExceptionInterface
psr-13	Hypermedia Links	LinkInterface, EvolvableLinkInterface
psr-14	Event Dispatcher	EventDispatcherInterface, StoppableEventInterface
psr-15	HTTP Handlers	RequestHandlerInterface, MiddlewareInterface
psr-16	Simple Cache	CacheInterface, InvalidArgumentException
psr-17	HTTP Factories	RequestFactoryInterface, ResponseFactoryInterface
psr-18	HTTP Client	ClientInterface, ClientExceptionInterface
psr-20	Clock	ClockInterface

Pre-flight Check

1. Verify valid PSR number:

   • If not provided, ask user which PSR to generate
   • If invalid PSR number, show list of supported PSRs

2. Check project structure:

   • Read composer.json for namespace configuration
   • Determine target directory structure

Instructions

Use the acc:psr-generator agent to generate PSR-compliant components:

Task tool with subagent_type="acc:psr-generator"
prompt: "Generate [PSR] implementation for [COMPONENT_NAME]. [META-INSTRUCTIONS if provided]

Requirements:
1. PHP 8.4 with declare(strict_types=1)
2. PSR-12 coding style
3. Final readonly classes where appropriate
4. Constructor property promotion
5. Include unit tests
6. Include usage examples
