pdf

Use this skill whenever the user wants to do anything with PDF files. This includes reading or extracting text/tables from PDFs, combining or merging multiple PDFs into one, splitting PDFs apart, rotating pages, adding watermarks, creating new PDFs, filling PDF forms, encrypting/decrypting PDFs, extracting images, and OCR on scanned PDFs to make them searchable. If the user mentions a .pdf file or asks to produce one, use this skill.

Quality

Content

72%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A highly actionable, code-dense skill body that covers PDF operations well, but it lacks validation checkpoints for its batch/destructive operations and points to reference files (REFERENCE.md, FORMS.md) that are not present in the bundle.

Suggestions

Add validation/verification steps after destructive or batch operations (e.g., confirm merged PDF page count, verify decrypted output opens, confirm split files are valid) to raise workflow clarity.

Either include the referenced REFERENCE.md and FORMS.md files in the bundle or inline their essential content, since the body currently points readers to files that do not exist.

Reference or surface the existing scripts/ helpers (e.g., fill_fillable_fields.py, convert_pdf_to_images.py) from the body so the available bundle is discoverable, and trim the redundant Quick Reference table that repeats the inline examples.

Dimension	Reasoning	Score
Conciseness	Mostly efficient headers-plus-executable-code with little concept padding, but the subscript/superscript section and the redundant Quick Reference table add minor over-explanation that could be trimmed.	4 / 5
Actionability	Extensive copy-paste-ready, executable code and CLI commands covering the common PDF operations (merge, split, extract, create, OCR, watermark, encrypt), matching the score-5 anchor for fully executable coverage.	5 / 5
Workflow Clarity	Operations are presented as independent recipes rather than a sequenced process, and batch/destructive operations (merge, encrypt, split) lack validation/verification checkpoints, capping this dimension at 3 per the feedback-loops guideline.	3 / 5
Progressive Disclosure	Section structure and one-level-deep references to REFERENCE.md/FORMS.md are clearly signaled, but those referenced files are absent from the bundle while the existing scripts/ directory is never referenced, leaving navigation gaps.	3 / 5

Description

100%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, third-person description that comprehensively enumerates concrete PDF operations and provides explicit, natural trigger guidance including the .pdf extension. It cleanly satisfies the what-and-when requirement with minimal conflict risk.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions (extract text/tables, merge, split, rotate, watermark, create, fill forms, encrypt/decrypt, extract images, OCR) with comprehensive coverage matching the score-5 anchor.	5 / 5
Completeness	Explicitly answers both 'what' (detailed action list) and 'when' ('whenever the user wants to do anything with PDF files', 'If the user mentions a .pdf file or asks to produce one') with concrete trigger phrases.	5 / 5
Trigger Term Quality	Includes natural terms and synonyms with file extension coverage ('PDF files', 'PDFs', '.pdf file'), matching the score-5 anchor for comprehensive natural-term coverage.	5 / 5
Distinctiveness Conflict Risk	Clear PDF-specific niche with distinct, file-extension-based triggers and minimal overlap risk with other skills.	5 / 5
	Total	20 / 20 Passed
