desktop_tool_catalog

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

No annotations are provided, so the description bears full responsibility for behavioral disclosure. It does not mention that the operation is read-only, requires no side effects, or any authentication needs. For a catalog tool, safety is assumed but not stated.

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 a single sentence in Chinese, concise and free of fluff. It immediately communicates the tool's purpose without unnecessary details.

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?

The description does not explain the format or content of the returned catalog (e.g., list of tool names, descriptions, or metadata). Despite no output schema, a user would benefit from knowing what the catalog contains. The context is incomplete for effective use.

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 has zero parameters, and schema coverage is 100% (empty object). According to guidelines, baseline for 0 parameters is 4. The description does not need to add parameter details since none exist.

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 states it returns a desktop MCP tool catalog to help select high-level tools. The verb 'return' and resource 'desktop MCP tool catalog' are specific. It clearly distinguishes from sibling tools that perform actions on desktop or other domains.

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 implies use for discovering available tools before selecting one. It provides clear context but does not explicitly state when not to use or compare to alternatives. However, the purpose is well-understood given the tool name and siblings.

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