Quality

Content

85%

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

A well-structured, actionable skill body with executable code at every tier and an explicit validation/retry feedback loop. Its only meaningful weakness is conciseness: the per-tier examples and the implementation pattern overlap, adding redundant tokens without adding guidance.

Suggestions

Consolidate the per-tier code blocks with the 'Implementation Pattern' function to remove duplicated library usage and reduce token cost.

Trim restating comments and narrative lines like 'Start with command-line tools that often handle edge cases better' since the commands already convey the intent.

DimensionReasoningScore

Conciseness

The body is mostly lean with minimal concept-explanation padding, but it duplicates the tier libraries across both the per-tier sections and the 'Implementation Pattern', and includes narration and comments that restate the code, so it could be tightened.

2 / 3

Actionability

Provides concrete executable shell commands, complete import-and-call Python snippets for multiple libraries, and a copy-paste-ready extract_pdf_resilient function with content thresholds.

3 / 3

Workflow Clarity

The Tier 1→2→3 sequence is clearly ordered with explicit validation checkpoints ('Check if output contains meaningful content'), a validate_extraction function, and an error-recovery feedback loop via the decision table.

3 / 3

Progressive Disclosure

No bundle files exist and none are needed; the body is self-contained and organized into clearly headed sections (Purpose, When to Use, Fallback Sequence, Decision Criteria, Best Practices), meeting the well-organized-sections bar for skills without external references.

Description

75%

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 concise, third-person description that explicitly covers what the skill does and when to use it, with a distinctive fallback niche. It is held back from the top specificity/trigger scores by describing a single capability and thin keyword coverage rather than a list of actions and natural user terms.

DimensionReasoningScore

Specificity

Names the PDF-extraction domain and a concrete mechanism ('multi-tier', 'sequential fallback strategies') plus a trigger condition, but lists essentially one capability rather than multiple distinct concrete actions.

2 / 3

Completeness

Answers both 'what' ('multi-tier PDF extraction with sequential fallback strategies') and an explicit 'when' trigger ('when initial reading fails'), satisfying the equivalent-trigger-guidance requirement rather than relying on implication.

3 / 3

Trigger Term Quality

Includes the natural term 'PDF extraction', but the 'when initial reading fails' clause describes a situation rather than user-spoken keywords and omits common variations like 'PDF', 'PDFs', or 'scanned PDF'.

2 / 3

Distinctiveness Conflict Risk

The multi-tier fallback/retry niche triggered on read failure is clearly distinct from generic happy-path PDF skills and unlikely to conflict.
