pdf

Use when tasks involve reading, creating, or reviewing PDF files where rendering and layout matter; prefer visual checks by rendering pages (Poppler) and use Python tools such as `reportlab`, `pdfplumber`, and `pypdf` for generation and extraction.

Quality

Content

100%

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

A tight, actionable PDF skill body: executable commands, a sequenced workflow with a render-verify checkpoint, and clean sectioning with no token waste. It is exemplary for a single-purpose skill.

DimensionReasoningScore

Conciseness

The body is lean and assumes Claude's competence — it never explains what a PDF is or how libraries work, and every section (workflow, dependencies, quality checks) earns its tokens, matching the 'lean and efficient' anchor.

3 / 3

Actionability

Provides fully executable, copy-paste-ready commands ('pdftoppm -png $INPUT_PDF $OUTPUT_PREFIX', 'uv pip install reportlab pdfplumber pypdf', brew/apt install lines) plus specific tool guidance, matching the level-3 anchor.

3 / 3

Workflow Clarity

A clear numbered sequence (render → generate → extract → re-render) with an explicit validation checkpoint ('After each meaningful update, re-render pages and verify alignment, spacing, and legibility') and a final-checks checklist, satisfying the level-3 anchor; the task is non-destructive so no feedback-loop cap applies.

3 / 3

Progressive Disclosure

A single-purpose, well-organized skill with clear sections and no nested references (only a single assets/pdf.png), so per the simple-skills note well-organized sections alone warrant a 3.

Description

85%

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, well-scoped description with an explicit 'Use when' trigger and concrete named tools and actions. Its only weakness is limited keyword variety, which keeps trigger-term quality at the mid level.

Suggestions

Broaden trigger-term coverage by adding natural synonyms like 'PDFs', '.pdf', or 'forms' alongside 'PDF files' so it matches more user phrasings.

Consider naming the form-handling or table-extraction use cases explicitly if those are in scope, to further sharpen distinctiveness.

DimensionReasoningScore

Specificity

Names multiple concrete actions ('reading, creating, or reviewing PDF files', 'rendering pages (Poppler)', 'generation and extraction') plus specific tools (reportlab, pdfplumber, pypdf), matching the multi-action anchor rather than the single-domain anchor at 2.

3 / 3

Completeness

Explicitly answers both 'what' (reading/creating/reviewing PDFs, generation and extraction via named tools) and 'when' via an explicit 'Use when...' trigger clause, matching the level-3 anchor.

3 / 3

Trigger Term Quality

Includes natural terms ('PDF files', 'rendering and layout', 'reading/creating/reviewing') but lacks synonym variety such as 'PDFs', '.pdf', or 'forms' seen in the level-3 example, so it sits at 'some relevant keywords but missing common variations'.

2 / 3

Distinctiveness Conflict Risk

Targets a clear PDF rendering/layout niche with specific tooling, making it unlikely to trigger for non-PDF skills; matches the 'clear niche with distinct triggers' anchor.
