Quality

Content

57%

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

The body is a well-organized, reasonably lean instruction-oriented overview that appropriately stays in one file, but it lacks executable code/commands and presents techniques as a catalog rather than a validated workflow. It scores mid-scale on most dimensions with progressive disclosure as its strongest aspect.

Suggestions

Add at least one executable example per main extraction path (e.g. a pdfplumber snippet for text/tables and a tesseract command line for OCR) to lift actionability.

Convert key flows into a short sequenced workflow with an explicit validation/verification checkpoint (e.g. verify extracted table row/column alignment before presenting).

Trim the 'Pitfalls to Avoid' section to non-obvious items only, removing guidance Claude already knows, to improve conciseness.

DimensionReasoningScore

Conciseness

The body is mostly lean bullet-form text with no 'what is a PDF' concept padding, but sections like 'Pitfalls to Avoid' restate things Claude already knows (e.g. 'Do not assume all text in a PDF is selectable') and several principle bullets are abstract, so it could be tightened to earn a 3.

2 / 3

Actionability

It names concrete tools (tesseract, pdf2image, cloud OCR) and specific output formats/data fields, but provides no executable code or commands, matching the 'some concrete guidance but incomplete / missing key details' anchor; for an instruction-only skill this partial concreteness is not a 1 but falls short of copy-paste-ready.

2 / 3

Workflow Clarity

The skill is organized as a catalog of techniques by document type rather than a sequenced multi-step workflow, and verification is only implicit ('Flag any content that could not be extracted reliably', 'note the confidence level') with no explicit validation checkpoints or feedback loops.

2 / 3

Progressive Disclosure

The skill is under 50 lines with no external references needed and no bundle files present, and the body is split into well-organized sections (Key Principles, Extraction Techniques, Analysis Patterns, Handling Complex Documents, Output Formats, Pitfalls), which per the rubric earns a 3 for simple single-file skills.

Description

50%

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 PDF-specific and reasonably clear on the 'what', but it reads as a role title rather than a concrete, trigger-rich description and omits any 'Use when...' guidance. It sits squarely at the middle of the scale across all dimensions.

Suggestions

Replace the role-title phrasing with concrete actions, e.g. 'Extract text, tables, and form fields from PDF files; summarize and compare documents.'

Add an explicit 'Use when...' trigger clause, e.g. 'Use when the user works with PDF files or mentions PDFs, forms, tables, or document extraction.'

Broaden trigger coverage with natural variations such as 'PDFs', '.pdf', 'forms', and 'tables'.

DimensionReasoningScore

Specificity

The description 'PDF content extraction and analysis specialist' names the domain (PDF) and a couple of actions (extraction, analysis) but frames them as a role title rather than listing multiple concrete actions like the score-3 anchor; it is above the score-1 vague examples because it is PDF-specific and action-adjacent.

2 / 3

Completeness

It answers 'what' (PDF content extraction and analysis) but provides no 'Use when...' clause or equivalent explicit trigger for 'when', so per the guideline completeness is capped at 2.

2 / 3

Trigger Term Quality

It contains the natural keyword 'PDF' and 'extraction', but lacks common variations a user would say such as 'PDFs', 'forms', 'tables', or '.pdf', matching the 'some relevant keywords but missing common variations' anchor.

2 / 3

Distinctiveness Conflict Risk

Scoping to PDF gives it a niche distinct from fully generic skills, but the broad term 'analysis' and absence of explicit distinct triggers mean it could still overlap with general document or data-analysis skills.
