Extract rich data from PDF pages including text spans with metadata, rendered PNG images, and page mapping. Creates persistent artifacts for downstream processing.

This skill should be used when the user asks to 'create a page', 'add a route', 'create a layout', 'add metadata', or 'set up a dynamic route'. Provides guidance for Next.js 15 App Router pages, layouts, and route handlers in app/**/*.tsx.

Implement robust error handling with user-friendly messages, fail-fast validation, specific exception types, and proper resource cleanup across the application. Use this skill when writing try-catch blocks, throwing or catching exceptions, implementing error boundaries, handling API errors, or managing error states in any part of the codebase. Apply this skill when validating inputs early (fail fast), providing clear actionable error messages to users without exposing security details, using specific exception types rather than generic errors, implementing centralized error handling at appropriate boundaries, designing for graceful degradation, implementing retry logic with exponential backoff, or ensuring resources are cleaned up in finally blocks. This skill ensures errors are caught and handled appropriately, user experience remains positive even when errors occur, security is maintained by not leaking sensitive information, and systems continue operating or degrade gracefully when non-critical services fa

Orchestrates the complete task planning workflow including codebase exploration, requirements gathering, and technical plan creation. Use when the user provides a new feature request, bug fix, or refactoring task that needs planning before implementation.

End-of-day command to capture what happened, consolidate notes, and set up for tomorrow. Use when the user types /wrap_up, says "end of day", "wrapping up", or "done for the day". Gathers git activity, integrates /note entries, and creates a daily summary in activity.md.
