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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds nothing meaningful beyond restating the endpoint and pointing to describe_operation for native request schemas; it does not describe return behavior, permissions, or any operational constraints.

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 short but contains a duplicated endpoint sentence that earns no place. The pointer to describe_operation is the only distinct content, making the overall structure repetitive rather than front-loaded with useful information.

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 retrieval tool with a nested query object, 0% schema description coverage, and no output schema, the description should at least identify the resource and clarify the parameters. It instead gives only the endpoint path and a pointer to describe_operation, leaving the agent without enough context to invoke the tool confidently.

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 description coverage is 0%, and the description only implies that :id is a path parameter. It does not explain the query object, the id format, or any constraints, so it fails to compensate for the undocumented parameters.

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 only repeats the HTTP endpoint already present in the title, effectively restating the name/title. It does not explain what an account mapping is or how this retrieval differs from sibling account-mapping tools such as get_account_mappings_5900b624a5f0d38407bcecf4 or get_account_mappings_effective_a95a52002e99b0c2b83ac112.

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 guidance on when to use this endpoint, when not to use it, or which sibling to choose for related queries. The agent is left to infer the use case entirely from the path.

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