Update the current user settings

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

Annotations already indicate the tool is destructive and not read-only. The description adds no additional context about behavioral traits, such as the need for confirmation (though 'confirm' parameter exists) or side effects. With annotations present, the burden is partially met, but more context would improve transparency.

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 very short but appears truncated and incomplete. It repeats the same phrase. It lacks necessary detail and is under-specified, which hurts usability despite its brevity.

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 destructive nature and the existence of safety parameters (confirm, dry_run), the description misses critical context. It does not explain the confirmation requirement or the preview mode. The output schema exists but is not referenced. The description is insufficient for an agent to use the tool safely.

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?

Schema coverage is 100% with descriptions for each parameter. The description does not add any additional meaning beyond what the schema provides, such as explaining the UserPayload or the purpose of 'confirm' and 'dry_run'. Baseline 3 due to high coverage.

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 title and description clearly state that this tool updates settings for the currently authenticated user. The 'me' in the name distinguishes it from other update tools like 'update_user' which target other users. However, the description does not explicitly differentiate it from siblings.

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?

No guidance is provided on when to use this tool versus alternatives. There is no mention of prerequisites, limitations, or when not to use it. The description simply states the action.

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