Merge multiple PDFs into one in a user-specified order, then hand off to pdf-optimizer for compression. Use whenever the user wants to "merge", "combine", "concatenate", "join", or "stitch" PDFs together — including phone photos or scans of math homework, lecture notes, or graph-paper pages, individual chapter PDFs, or per-page exports that need to be assembled into a single document. Prevents the common mistake of using `gs` to merge (which silently re-encodes images and bloats scanned input), and shows the right combination of qpdf for ordered concatenation plus pdfunite/mutool fallbacks. Pairs with pdf-optimizer for the post-merge compression step.

Diagnose and compress large PDFs while preserving text fidelity. Use whenever the user wants to "shrink", "compress", "optimize", or "reduce the size of" a PDF — especially scanned books, OCRed documents, or files over ~50MB. Also use when the user complains a PDF is "too big", "huge", "bloated", or "won't fit". The skill prevents the common mistake of reaching for `gs -dPDFSETTINGS=/ebook` (which silently *grows* MRC-encoded PDFs by destroying their layered structure) and instead picks the right tool based on what's actually inside the PDF.

Debug running Python processes using Python 3.14+ sys.remote_exec(). Inject debugging scripts to get stack traces from stuck processes, including gevent-based Celery workers with greenlet introspection.

Use when the user wants to provision AWS GPU instances, check GPU instance status, terminate instances, manage EBS data volumes, clean up cloud resources, check GPU vCPU quotas, or request quota increases. Wraps the aws-bootstrap CLI for EC2 GPU instance lifecycle management (launch, status, terminate, cleanup, list, quota).
