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.

An efficient, highly actionable skill body: every command is copy-paste ready and the structure is clean for a simple single-purpose tool. The only improvement is trimming the redundancy between the intro paragraph and the When to Use bullets.

DimensionReasoningScore

Conciseness

The body is lean with no over-explanation of concepts Claude already knows; all guidance is commands and brief directives. Not 5 because the intro paragraph and the three "When to Use" bullets restate the same triggers (web pages, docs/articles, token efficiency), which could be merged.

4 / 5

Actionability

Fully executable copy-paste commands throughout: `npm install -g defuddle`, `defuddle parse <url> --md`, `-o content.md`, `-p title/description/domain`, plus a format table. The specific examples cover the common cases, matching the 5 anchor.

5 / 5

Workflow Clarity

A simple single-purpose skill where the single action is unambiguous ("Always use `--md` for markdown output"), with the install prerequisite stated. It is a read-only extraction with no destructive or batch operation, so no validation checkpoint is required; per the simple-skill note this can score 5.

5 / 5

Progressive Disclosure

The body is under 50 lines with no need for external references, and content is well-organized into clear sections (When to Use, Usage, Output formats). Per the under-50-lines guideline, this merits a 5.

Description

87%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.

A strong description with concrete actions, explicit what/when guidance, and smart positioning against WebFetch. The only weakness is slightly incomplete synonym coverage for natural trigger terms.

DimensionReasoningScore

Specificity

The description lists several concrete actions — "Extract clean markdown content from web pages using Defuddle CLI, removing clutter and navigation to save tokens" — naming the tool and specific behaviors. It falls short of 5 because coverage has minor gaps (e.g., metadata extraction, output formats are not mentioned).

4 / 5

Completeness

Explicitly answers both what ("Extract clean markdown content from web pages using Defuddle CLI") and when ("Use instead of WebFetch when the user provides a URL to read or analyze, for online documentation, articles, blog posts, or any standard web page") with concrete trigger phrases. Not 4 because the when-clause is already fully explicit and specific.

5 / 5

Trigger Term Quality

Good keyword coverage with natural phrases users would say: "URL to read or analyze", "online documentation, articles, blog posts", and "standard web page". Not 5 because common synonyms like "link", "webpage", or "scrape" are missing.

4 / 5

Distinctiveness Conflict Risk

The description carves out a clear niche (web content extraction) and explicitly disambiguates against the nearest competitor: "Use instead of WebFetch when the user provides a URL". Conflict risk is minimal, matching the 5 anchor.
