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

Annotations already declare this is a safe, read-only, non-destructive, non-open-world operation. The description adds one useful behavioral detail, that location is off by default, but it does not describe the return shape or other default privacy settings; with annotations carrying the safety profile, this is adequate but not rich.

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 short sentences with no wasted wording, and the purpose is front-loaded. The second sentence adds a useful default-state fact without distracting from the main action.

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 no-parameter read-only tool, the description is nearly complete: it states what is returned and gives one default setting. It does not explain whether all privacy settings are returned or how this relates to set_privacy, but no output schema or parameter documentation is needed here.

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?

There are zero parameters, so parameter semantics are not applicable and the baseline is 4. The description does not need to explain parameter meaning, and the empty schema is consistent with the tool's no-argument nature.

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, 'Show', and resource, 'AskMyEV privacy settings', so the agent knows this is a read operation. It implicitly contrasts with the sibling set_privacy by using 'Show', but it does not explicitly name that alternative or clarify scope beyond privacy settings.

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 this tool is used when the agent needs to view the user's privacy settings, but it provides no explicit when-to-use guidance or exclusions. It does not mention when to use this versus set_privacy, leaving that routing inference to the agent.

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