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 real value by disclosing the response contents (items with status, tracking numbers and carriers, images, options, totals, billing/shipping addresses, discounts, metadata) and the underlying endpoint, though it says nothing about error behavior for unknown IDs or rate limits.

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?

One dense but front-loaded sentence that opens with the identifying constraint, then lists return contents. The trailing 'GET /orders' is slightly imprecise (the real path is /orders/{id}) and is the only marginal filler.

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 one-parameter read tool with full schema coverage and read-only annotations, the description covers identification, return shape, and scope. With no output schema, enumerating returned fields is exactly the missing piece, and it is supplied.

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 coverage is 100% and the schema already defines order_id as the 'Gooten Safe Order ID' with the search tool as its source. The description's phrase 'by its Safe Order ID' merely echoes that, adding no format or validation detail beyond the schema; baseline 3 applies.

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 (get one order) plus the key discriminator, the Safe Order ID, and enumerates what comes back (items, status, tracking, addresses, totals). An agent can distinguish it from gooten_search_orders without opening either schema.

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 single-order-by-ID scope implies when to use it, and the schema points to gooten_search_orders as the source of the ID, but the description itself never states when to prefer this over the search tool or what to do if the ID is unknown.

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