Quality

Content

85%

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 well-organized with executable examples and clear sequencing. Its main weakness is redundancy across the steps and error-handling sections, which slightly hurts conciseness.

Suggestions

De-duplicate the file-existence check and pdftotext invocation by presenting the canonical pattern once and referencing it, rather than repeating it in the Error Handling section.

Trim the speculative read_file parameter-naming tangent ('filetype' vs 'file_type') unless it documents a verified behavior, as it adds uncertainty without actionable value.

DimensionReasoningScore

Conciseness

The file-existence check and pdftotext invocation are repeated across Steps 1, 2, and the Error Handling function, and the speculative read_file parameter naming tangent adds padding; it is mostly efficient but could be tightened.

2 / 3

Actionability

Provides fully executable run_shell/pdftotext commands, an options table, copy-paste-ready snippets, and a prerequisite availability check.

3 / 3

Workflow Clarity

Steps are clearly sequenced (verify file, extract, handle errors) with a returncode/stderr check; the operation is non-destructive so a full validate-fix-retry loop is not required.

3 / 3

Progressive Disclosure

No bundle files exist; the single self-contained SKILL.md is well-organized into clear sections, which is appropriate for a simple skill.

Description

57%

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 clear and specific about a single PDF extraction task but lacks an explicit use-when trigger and broader natural keyword coverage. It is distinctive and concrete, just not comprehensive.

Suggestions

Add an explicit 'Use when...' clause, e.g. 'Use when read_file returns binary or garbled PDF content and you need searchable text.'

Broaden trigger terms to include 'PDFs', '.pdf', and 'document extraction' for better keyword coverage.

Consider mentioning additional concrete actions (e.g. preserving layout, extracting specific page ranges) to lift specificity from a single action to multiple.

DimensionReasoningScore

Specificity

"Extract text from PDF files using pdftotext" names a concrete action and tool, but describes only a single action rather than multiple specific capabilities.

2 / 3

Completeness

The description answers "what" but has no explicit "Use when..." trigger clause, which per the guidelines caps completeness at 2.

2 / 3

Trigger Term Quality

"PDF files" and "pdftotext" are relevant terms a user might say, but common variations like PDFs, .pdf, or "document extraction" are missing.

2 / 3

Distinctiveness Conflict Risk

The narrow focus on PDF text extraction via pdftotext as a read_file fallback is a clear niche unlikely to trigger for other skills.
