list_mqtt_clients

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the tool lists clients but doesn't describe how it behaves—e.g., whether it returns all clients or paginated results, if it requires authentication, what the output format is, or any rate limits. This leaves significant gaps for an agent to understand the tool's operation.

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, clear sentence that efficiently conveys the core purpose without unnecessary words. It's front-loaded with the main action and resource, making it easy to parse, though its brevity contributes to gaps in other dimensions.

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?

Given the tool's complexity (a listing operation with one undocumented parameter), lack of annotations, and no output schema, the description is incomplete. It doesn't cover parameter usage, behavioral details, or output expectations, making it insufficient for an agent to effectively invoke the tool without additional context.

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 input schema has one parameter ('request') with 0% description coverage, and the tool description provides no information about parameters. It doesn't explain what 'request' should contain (e.g., filtering criteria, pagination options) or its format, leaving the parameter entirely undocumented and unusable without external knowledge.

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 clearly states the tool's purpose with a specific verb ('List') and resource ('MQTT clients connected to your EMQX Cluster'), making it immediately understandable. However, it doesn't explicitly differentiate from sibling tools like 'get_mqtt_client' (which likely retrieves a single client) or mention the scope of listing (e.g., all clients vs. filtered).

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention when to prefer 'list_mqtt_clients' over 'get_mqtt_client' (e.g., for bulk retrieval vs. single client details) or 'kick_mqtt_client' (for management actions). There's also no context on prerequisites or limitations.

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