Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description states 'No authentication required' and 'Tracks the download', disclosing a side effect and access requirement. Annotations are all false (not read-only, destructive, etc.), but the description adds useful behavioral context beyond annotations. It does not fully elaborate on other possible side effects, but for this tool the disclosed information is adequate.

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 description is three concise sentences, front-loaded with the core purpose, and includes only high-value information: return format, client support, side effect, and auth requirement. No waste.

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?

For a simple 2-parameter tool with an output schema, the description covers the essential context: what it returns, for which clients, the tracking side effect, and auth. No need to detail return values since an output schema exists.

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?

Schema coverage is 100% with both parameters already described with examples ('thinkneo-control-plane' and client types). The description does not add parameter-level details, but since the schema fully carries that burden, baseline 3 is appropriate.

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 description uses a specific verb ('Get') and resource ('installation config for an MCP server from ThinkNEO Marketplace'). It also differentiates from sibling registry tools by explicitly mentioning the ready-to-use JSON config for specific clients (Claude Desktop, Cursor, Windsurf, custom), making its purpose unmistakable.

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?

The description clearly implies this tool is for retrieving installation configuration, and provides context about the return format and no-auth requirement. It does not explicitly mention alternatives or when-not-to-use, but the context is clear enough for an agent to recognize this is the installation-focused sibling among registry tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
