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

No annotations are provided, so the description carries the full burden. It mentions the tool retrieves 'comprehensive details' but does not disclose behavioral traits such as authentication requirements, rate limits, error conditions, or what happens if the account does not exist. The description adds minimal context beyond the basic operation.

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 appropriately sized with two sentences, front-loaded with the core purpose and followed by a usage context. It avoids unnecessary words, though the second sentence could be slightly more specific to enhance clarity.

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 low complexity (1 parameter, no nested objects) and lack of output schema, the description is adequate but incomplete. It specifies what details are retrieved but does not cover return format, error handling, or other contextual nuances needed for full understanding, leaving gaps for the agent.

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 input schema has 100% description coverage, with the parameter 'account_id' documented as 'The account ID.' The description does not add any additional meaning or examples for the parameter, so it meets the baseline of 3 where the schema does the heavy lifting.

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's purpose with specific verbs ('Get comprehensive details') and resources ('specific user account'), and distinguishes it from siblings like 'list-accounts' by specifying retrieval of detailed information for a single account rather than listing multiple accounts.

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 usage for 'user management and access control,' providing some context, but does not explicitly state when to use this tool versus alternatives like 'get-current-account' or 'update-account,' nor does it mention prerequisites or exclusions.

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