Quality

Content

65%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 skill is highly actionable with copy-paste-ready commands across many MCP scenarios, but it is over-long with repeated examples and inlines reference material that would benefit from separate files. Destructive workflows lack explicit validation checkpoints.

Suggestions

Move the server catalog, transport, and authentication detail into reference files (e.g., SERVERS.md, AUTH.md) and link to them from a concise overview to improve progressive disclosure.

Add explicit validate-then-proceed checkpoints to the Complete Workflow for destructive calls (e.g., verify a write_file succeeded by reading the file back before continuing).

De-duplicate examples that recur between Discovery, Common MCP Servers, and Best Practices to tighten token use.

DimensionReasoningScore

Conciseness

The body is mostly executable commands with little concept over-explanation, but several sections repeat earlier examples (e.g., Common MCP Servers re-lists filesystem/memory/github commands already shown in Discovery) and could be tightened.

3 / 5

Actionability

Commands are fully executable and copy-paste ready, with concrete examples spanning filesystem, memory, HTTP, and auth cases covering the common usage.

5 / 5

Workflow Clarity

Discovery steps and the Complete Workflow are sequenced, but workflows involving destructive tool calls (write_file, delete) lack explicit validate-after-call checkpoints; the destructive/batch cap limits this to 3 despite a present error-handling best practice.

3 / 5

Progressive Disclosure

Content is well-sectioned with a Quick Reference table, but ~370 lines of reference material (server catalog, auth, transports) are inlined in SKILL.md with no bundle files to split deeper detail into; the under-50-line exception does not apply.

Description

61%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 clearly conveys the skill's purpose and domain with concrete discoverable objects, but lacks an explicit 'when to use' trigger clause, which caps completeness. It is largely distinct and uses natural terminology.

Suggestions

Add an explicit 'Use when...' clause (e.g., 'Use when you need to call an MCP server without pre-configuring it, or when you want to discover available MCP tools/resources/prompts').

Broaden trigger terms with common synonyms (e.g., 'MCP integration', 'MCP tools', 'probe an MCP server').

List a couple more concrete actions (e.g., 'invoke tool calls', 'read resources', 'manage server aliases') to lift specificity.

DimensionReasoningScore

Specificity

Names the domain (MCP servers via the mcp CLI) and one concrete action ('discover tools, resources, and prompts'), but does not enumerate multiple distinct actions; it is a single action across three object types.

3 / 5

Completeness

Clearly states what the skill does, but there is no explicit 'Use when...' trigger clause; per the guidelines, a missing explicit trigger caps completeness at 3.

3 / 5

Trigger Term Quality

Includes natural terms a user would say ('MCP servers', 'tools, resources, and prompts', 'on-demand') with good coverage, though a few natural synonyms or variants are absent.

4 / 5

Distinctiveness Conflict Risk

The on-demand mcp CLI niche is mostly distinct with minimal overlap, though it could collide with other MCP-related skills absent explicit triggers.
