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.

A well-engineered skill body: executable examples, a clearly sequenced workflow with validation checkpoints, and tight organization that surfaces non-obvious pitfalls without padding. Minor conciseness trimming is the only lever left.

DimensionReasoningScore

Conciseness

Largely lean and assumes Claude's competence; detailed sections (env placeholders, output_file_path, common pitfalls) earn their tokens by covering non-obvious gotchas, with only minor instances that could be trimmed.

4 / 5

Actionability

Fully executable, copy-paste-ready code blocks cover the common cases (list/connect/schema/call, add stdio/http servers, persist output to a file) with concrete parameter shapes.

5 / 5

Workflow Clarity

Clear sequenced workflow with status-based branching, explicit validation rules (always check result.ok, always fetch schema before calling), and an error-recovery feedback loop in the example.

5 / 5

Progressive Disclosure

Single self-contained SKILL.md with well-organized, clearly headed sections and no need for external bundle files; navigation is straightforward.

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, concise description that names concrete actions and pairs them with an explicit, distinctive load-trigger. Coverage of the full capability set is the only minor gap.

DimensionReasoningScore

Specificity

Lists several concrete actions ('Discover, connect to, and invoke tools on MCP servers') with only minor gaps in coverage (e.g., add/remove server not mentioned); falls just short of the comprehensive 5 anchor.

4 / 5

Completeness

Clearly answers both what ('Discover, connect to, and invoke tools on MCP servers') and when ('When the user message contains [@mcp:...] mention, you MUST load this skill first') with a concrete trigger phrase.

5 / 5

Trigger Term Quality

Strong natural keywords ('MCP', 'Model Context Protocol', 'MCP servers', 'MCP tools') plus the explicit [@mcp:...] trigger token, though a few common synonyms or variations are absent.

4 / 5

Distinctiveness Conflict Risk

A clear MCP-specific niche with a distinct [@mcp:...] trigger token, making conflict with other skills minimal.
