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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so safety is covered. The description adds the REST endpoint and the returned field set, but says nothing about pagination limits, result caps, or auth requirements beyond the structured fields.

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 sentences, no waste: the resource and returned fields come first, and the endpoint is appended as a compact identifier. Every clause earns its place.

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?

With no output schema, the description usefully names the fields returned, and pagination/sorting are covered by the schema. The only gap is the lack of explicit differentiation from the single-record get_customer_equipment sibling.

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 100%, so paging, sorting, field selection and expand are fully documented in the schema itself. The description contributes no additional parameter meaning, which is the correct baseline when 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?

States a specific verb and resource ('List the equipment on file for a customer') and even enumerates the fields returned (make, model, serial, warranty/install dates), so the agent knows exactly what comes back. It does not explicitly distinguish itself from the sibling get_customer_equipment, leaving the list-vs-single distinction to be inferred from the names.

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?

Usage is implied by the 'for a customer' framing and the required customer_id, but there is no explicit when-to-use guidance, no mention of when to prefer get_customer_equipment, and no note about how to page through large equipment sets beyond what the schema says.

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