Most tools are distinct by resource and action, but `pdf_extract_pages` and `pdf_split` overlap substantially since both can select pages and output a new PDF; the only clear difference is 'range' vs 'specified pages.' `pdf_organize` also handles page-level changes, so there is a minor three-way boundary issue around page manipulation.

The `img_`/`pdf_` prefix pattern and lowercase operation names are consistent and readable. Minor deviations exist: `pdf_metadata` is a noun-style name for a read/write operation, and `pdf_image_watermark` is longer than `pdf_watermark`, but these are still predictable within the set.

14 tools is a well-scoped count for a PDF/image toolbox. Each major workflow—conversion, compression, merging, splitting, encryption, watermarking, metadata, and page organization—has a dedicated tool without the list feeling bloated.

The tool surface covers the main PDF lifecycle well, including creation from images, conversion to images, merging, splitting, extracting pages, compressing, encrypting/decrypting, watermarking, and metadata. Minor gaps remain, such as reordering pages, OCR, or inserting blank pages, but these are not critical for the apparent toolbox purpose.
