list_billing_transfer_reseller_accounts_with_tenants

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

Annotations declare readOnlyHint=true and destructiveHint=false, so the read-only nature is covered. The description adds meaningful behavioral context by explaining that region, iamStatus, and lastRefreshTime are inherited from the parent DPMA root, and that the reseller node carries no IAM/region metadata. This goes beyond the annotations and clarifies the data structure.

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 starts with a broad, somewhat extraneous phrase about managing mappings, then gets to the core purpose. It includes useful detail about inherited metadata but could be more streamlined. The two-sentence structure is acceptable but the first sentence is vague and could be removed without losing value.

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?

The description gives good context on the output (reseller nodes with tenants) and metadata inheritance, but it lacks explanations for the parameters and does not clarify the exact conditions under which the tool is used vs other listing tools. With no output schema and low parameter coverage, the description could be more complete, but it covers the main functional aspect.

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 description does not mention any of the three parameters (X-Tenant-Id, includeRevoked, customerContext). Schema description coverage is only 33% (only customerContext has a description), and the description does not compensate by explaining what includeRevoked or X-Tenant-Id mean, or how they affect the results.

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 lists reseller PMA nodes with their connected end-customer tenants, and explicitly identifies it as the reseller-tier analog of a specific API. This distinguishes it from sibling tools like list_billing_transfer_program_management_accounts and list_billing_transfer_reseller_accounts by specifying the 'reseller-tier' scope and the inclusion of tenants.

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 explicit guidance on when to use this tool versus the sibling list_billing_transfer_program_management_accounts, list_billing_transfer_reseller_accounts, or list_billing_transfer_end_customers_by_reseller. The description mentions it is 'the reseller-tier analog' of another API, but does not explain in which scenarios one would prefer this over the other listing tools.

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