Account holder name

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

Annotations already fully cover the behavioral profile (readOnlyHint, idempotentHint, destructiveHint=false, openWorldHint), which lowers the bar, but the description adds nothing beyond that: no note on fallback behavior when no holder name exists, no indication of null/empty results, and no hint about which account/resource it applies to.

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?

A single short sentence with no filler and the essential information front-loaded. It is not over-verbose, though its brevity borders on under-specification rather than disciplined conciseness.

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 zero-argument getter whose annotations carry the safety profile and which has no output schema, the description is barely adequate. It does not clarify the return shape (a plain name string vs. a holder object) nor its relationship to get_account_holder, which is the main ambiguity an agent would face.

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 takes zero parameters, so there is nothing for the description to disambiguate; the baseline of 4 applies. Schema coverage is 100% and there are no arguments to misread.

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 states a verb and a resource ('Returns the account holder's name'), but it is essentially a verbatim restatement of the tool name/title. It gives no differentiation from close siblings such as get_account_holder, get_individual_details, or get_joint_account_details, leaving the agent unable to tell why this narrower tool exists.

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?

There is no when-to-use guidance, no statement of prerequisites, and no mention of the sibling get_account_holder that presumably returns the same information plus more. The agent must infer selection entirely from the tool name.

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