Changes observed during successful MCP inspections.
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, openWorldHint=false and destructiveHint=false, so the safety profile is covered. The description adds that the tool is bound to one specific site and what fields it returns, but says nothing about auth, rate limits, or freshness of the overview, so it only modestly exceeds the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The first paragraph is front-loaded and useful, but the entire second paragraph is marketing copy about the site's camera/IoT products that does nothing to help an agent select or invoke the tool. Roughly half the description is filler that does not earn its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With no input parameters, no output schema, and annotations covering the safety profile, the description supplies the key missing context: which site it targets and what information it returns. It is essentially complete for such a simple read tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool takes zero parameters, so there is nothing for the description to disambiguate; the baseline for a 0-param tool is 4. The description correctly gives no parameter guidance because none is needed.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The first sentence gives a specific verb+resource: it returns an overview of the site, and it enumerates exactly what comes back (type, intro text, page count, main pages). The purpose is clear, but it never distinguishes itself from siblings like get_page or list_pages, so an agent must infer the boundary.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
It explicitly states when to use it: '最初にサイトの全体像をつかみたいときに使います' (use when you first want to grasp the whole picture), which implies an ordering relative to the other site tools. There are no explicit exclusions or named alternatives, so it falls short of a 5.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
