get_account_details

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

There are no annotations, so the description carries the full burden. It communicates that the tool returns account information, which implies a read-only operation, but it does not explicitly state that it has no side effects, nor does it mention authentication needs or rate limits. The absence of any parameter-related side effects mitigates this, but the description could be more explicit about safety and operational characteristics.

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 two sentences, front-loaded with the tool's purpose, and every sentence adds relevant information. There is no redundant or filler content.

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 simplicity (no parameters) and the presence of an output schema, the description is complete enough. It spells out what data the agent can expect (email, limits, counts) and is well aligned with the sibling context, making the integration context fully understandable.

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 accepts zero parameters, so there is no parameter semantics burden on the description. Per the scoring baseline for 0-parameter tools, a score of 4 is appropriate. The description does not need to add parameter-level detail.

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 and resource: 'Get UptimeRobot account details.' It clearly distinguishes itself from sibling tools like get_monitors and get_alert_contacts by focusing on account-level information. It also enumerates the return content (email, monitor limits, monitor counts), leaving no ambiguity about its purpose.

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 makes the context clear: use this tool when you need account-level details. There is no sibling tool that overlaps with 'account details,' so no exclusions or alternatives are strictly necessary. However, it does not explicitly state 'when to use this vs. others,' so it stops short of a perfect score.

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