Get Instances Limits Customers By Id

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

The annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, and the description is consistent with a plain read. However, it adds nothing beyond that — no indication of whether the response is a single limits object, whether limits are per-customer or per-instance, or how missing limits are surfaced.

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?

Two words are trivially concise but are under-specification rather than economy; there is no front-loaded scope or constraint because there is almost no content at all.

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 two-parameter lookup inside a very large, densely overlapping sibling set, with no output schema and no annotation beyond safety hints, the definition supplies none of the disambiguating context an agent needs to call it correctly.

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 both required parameters ('id' and 'instance_id') are documented only by string-length constraints and an example. The description never clarifies whether 'id' refers to a customer ID or a limits record ID, so it fails to compensate for the coverage gap.

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 says 'Retrieve Customer Limits', which identifies a verb and a resource, so an agent can guess the general operation. But it gives no scope or qualifier detail and does nothing to distinguish this from close siblings like GetV1InstancesCustomersById, GetV1InstancesCustomersLimitIncrease, or GetV1InstancesCustomers.

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 statement of when to use this tool, when not to, or which sibling to prefer. In a sibling set containing both customer reads and limit-increase reads, that omission leaves selection entirely to inference from the name.

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