get_account_status

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

With no annotations, the description carries the full burden of explaining behavior. It discloses that it performs a GET request to a specific endpoint, returns an AccountStatus object with possible status values, and suggests a follow-up action based on the result. It does not explicitly state read-only or authentication details, but those are implied by the retrieve action and the simple nature of the tool.

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 well-structured: a clear first sentence, a technical detail, a return specification, and a practical use case. Every sentence adds value, and the use case is concise but illuminating. No filler or redundancy.

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 absence of an output schema, the description adequately explains the return format, including the status field and all possible values. It also provides a real-world scenario, making the tool's purpose and expected inputs/outputs fully clear for a parameterless operation.

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, so no parameter explanation is needed. Per the rubric, a baseline of 4 applies for parameterless tools. The description focuses instead on the return value and usage context, which 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 ('Retrieve') and identifies a precise resource ('MQTT connection status for the linked account from the Busy Bar device'), making its purpose unmistakable. This distinguishes it clearly from sibling tools like get_transport or get_account_info, which cover different 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 explicitly states a use case: 'Check MQTT connectivity before pushing data that requires cloud sync; if the account is not connected, queue operations locally until reconnection.' This gives the agent concrete guidance on when to call the tool, and implies when it may be unnecessary, with no comparable alternative among siblings.

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