57%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A well-organized single-file overview that correctly steers toward verifying the evolving SDK API, but its core registration and transport guidance is non-committal and doc-deferring rather than copy-paste executable, and it carries some redundant explanation and repeated reminders. Strongest on structure, weakest on actionability and conciseness.
Suggestions
Replace the multi-variant registration guidance ("registerTool() or tool() depending on SDK version... check the docs") with one concrete, copy-paste-ready registration example for the current SDK, and move alternate signatures into a clearly labeled 'SDK version differences' note.
Add an executable stdio connection snippet instead of describing it abstractly ("create a stdio transport and pass it to your server's connect method"), so transport setup is actionable rather than deferred to the docs.
Trim the repeated 'check Context7/official MCP docs' reminders (they appear ~5 times) to a single canonical note, and drop the opening definition of what MCP/tools/resources are since Claude already knows this.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Mostly efficient and well-sectioned, but it opens by explaining what MCP/tools/resources are ("The Model Context Protocol (MCP) lets AI assistants call tools, read resources, and use prompts from your server") and repeats the "check Context7/official docs" reminder roughly five times. It is not a padded wall of text, so it clears level 1 but does not earn level 3. | 2 / 3 |
Actionability | It gives one concrete executable snippet ("npm install @modelcontextprotocol/sdk zod" and the McpServer construction), but the core guidance defers to the docs with multiple variant signatures ("registerTool() or tool() depending on SDK version", "some versions use server.tool(name, description, schema, handler), others use server.tool({ name, description, inputSchema }, handler)") and the stdio section has no actual code. This is incomplete, not copy-paste-ready. | 2 / 3 |
Workflow Clarity | An implicit build sequence exists (install -> create server -> register tools/resources -> choose transport), and there is sound architectural advice ("Keep server logic independent of transport"), but it is not presented as an explicit numbered sequence and has no validation checkpoints. It is not a destructive/batch workflow, so the level-1 cap does not apply, but it still lacks the explicit sequenced workflow needed for level 3. | 2 / 3 |
Progressive Disclosure | No bundle files exist (references/, scripts/, assets/ are absent) and the skill is a single ~75-line SKILL.md with clear, well-organized sections (When to Use, How It Works, Examples, Best Practices, Official SDKs). At this size there is no content that needs splitting out, so the monolithic, well-sectioned structure earns level 3. | 3 / 3 |
