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.

The body is highly actionable and reasonably concise, but it suffers from broken progressive disclosure (referenced files are absent) and lacks validation checkpoints for batch operations. Fixing the missing referenced files and adding output-verification steps would raise the two weakest dimensions.

Suggestions

Provide the missing REFERENCE.md and FORMS.md files referenced in the Overview, Quick Reference table, and Next Steps, or remove the references and inline the essential guidance, so navigation does not dead-end.

Add a verification step after batch/destructive operations (e.g., reopen merged/split/encrypted output with PdfReader and assert page count or successful decrypt) to introduce a validate-then-proceed feedback loop.

Trim redundant inline code comments and consider condensing or removing the Quick Reference table, which duplicates the per-tool sections above it.

DimensionReasoningScore

Conciseness

Mostly lean code-first content that assumes Claude's competence (no "what is a PDF" padding), but includes redundant inline code comments and a Quick Reference table that repeats the preceding sections; trimmable rather than lean.

4 / 5

Actionability

Provides copy-paste-ready, executable code and commands across pypdf, pdfplumber, reportlab, pdftotext, qpdf, and pytesseract, covering the common PDF tasks concretely.

5 / 5

Workflow Clarity

Tasks are presented as self-contained snippets with clear implicit sequences, but batch operations (merge, split, encrypt, watermark) lack any validation/verification checkpoint that the output PDF is valid, so the batch-operation cap of 3 applies.

3 / 5

Progressive Disclosure

Structure is well organized and references are clearly signaled, but the repeatedly referenced REFERENCE.md and FORMS.md do not exist in the bundle, so navigation dead-ends rather than resolving one level deep.

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.

The description is comprehensive and well-structured, explicitly stating both what the skill does and when to use it with natural trigger terms and file extensions. It is a strong, low-conflict trigger description.

DimensionReasoningScore

Specificity

Lists many concrete actions ("reading or extracting text/tables", "combining or merging", "splitting", "rotating pages", "adding watermarks", "filling PDF forms", "encrypting/decrypting", "extracting images", "OCR"), giving comprehensive coverage of the PDF domain.

5 / 5

Completeness

Explicitly answers both what (the enumerated action list) and when ("Use this skill whenever the user wants to do anything with PDF files... If the user mentions a .pdf file or asks to produce one, use this skill").

5 / 5

Trigger Term Quality

Covers natural terms and synonyms including "PDF files", "PDFs", "PDF forms", and the ".pdf file" extension, matching the comprehensive anchor.

5 / 5

Distinctiveness Conflict Risk

Has a clear PDF-only niche with distinct triggers (".pdf file", "asks to produce one"), giving minimal conflict risk with other skills.
