Quality

Content

92%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 well-structured and highly actionable, with executable code, a clear validated fallback workflow, and appropriate organization for a simple single-purpose skill. Only minor conciseness trimming would bring it to the top of the scale.

DimensionReasoningScore

Conciseness

Content is mostly lean with executable code blocks and minimal padding; the brief 'Problem' explanation adds useful context but could be trimmed slightly, keeping it just below the leanest anchor.

4 / 5

Actionability

Provides copy-paste ready, executable bash and Python for four methods plus a concrete example using run_shell and execute_code_sandbox, covering the common cases fully.

5 / 5

Workflow Clarity

A clear 4-step check-then-fallback workflow with an explicit validation checkpoint (step 2 inspects output for failure modes) before falling back; no destructive/batch operation, so no cap applies.

5 / 5

Progressive Disclosure

A single, self-contained SKILL.md with no bundle files, organized under clear section headers; per the simple-skill exception, well-organized short content scores 5 without external references.

Description

50%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 states a clear capability and an implicit trigger condition but lacks an explicit 'Use when...' clause and natural trigger synonyms, landing at the midpoint across all dimensions. It is functional but not as discoverable or comprehensive as the top anchors.

Suggestions

Add an explicit 'Use when...' clause naming concrete triggers, e.g. 'Use when read_file fails on a PDF or when the user needs reliable PDF text extraction'.

Include natural synonyms and file extensions users actually say, such as 'PDFs', '.pdf files', and 'extract text from PDF'.

Expand the action list slightly (e.g. mention metadata or table extraction) to push specificity and distinctiveness above the midpoint.

DimensionReasoningScore

Specificity

Names the PDF domain and the concrete action 'extract PDF text' via shell commands or Python libraries, but lists only a single action without comprehensive coverage of related operations.

3 / 5

Completeness

Has a clear 'what' (extract PDF text via shell/Python) but only an implicit 'when' (the 'when read_file PDF handler fails' clause), with no explicit 'Use when...' trigger guidance, which caps completeness at 3 per the rubric.

3 / 5

Trigger Term Quality

Includes relevant terms ('PDF text', 'PDF', 'read_file PDF handler') but omits natural synonyms users say like 'PDFs', '.pdf', or 'extract text from a PDF'.

3 / 5

Distinctiveness Conflict Risk

Scoped to a fallback niche (when read_file fails), which adds specificity, but 'extract PDF text' still overlaps broadly with general PDF skills, so overlap risk remains moderate.
