list_accounts

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

The description discloses that the accounts are dummy (fake) and that responses undergo schema validation. With no annotations, it partially carries the transparency burden, but it doesn't clarify side effects, authentication, or rate limits; however, for a zero-parameter read-like operation, this is somewhat adequate.

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 a single concise sentence with no redundant information. It front-loads the action and resource.

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 has no parameters and an output schema exists, the description covers the essential purpose. It could benefit from stating the intended use case (e.g., testing/validation), but the term 'dummy' implies it adequately.

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 the schema fully covers parameter semantics. The baseline for zero parameters is 4, and the description need not provide additional parameter details.

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 clearly states the tool returns 1-2 dummy accounts, using a specific verb and resource. It distinguishes itself from get_accounts by noting these are dummy accounts, though it doesn't explicitly name alternative tools.

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 usage context is provided. The description does not mention when to use this tool versus get_accounts or other siblings, nor any exclusions or prerequisites.

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