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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds only that the response is the 'full details' of the record, implying richer output than search results, but says nothing about error behavior for a bad id or output 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?

One short sentence that front-loads the resource and scope, with every clause earning its place through the id-provenance hint.

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 single-parameter read tool with annotations covering the safety profile and no output schema, the description supplies the essential lookup context. Only the behavior on an invalid or missing id is left unstated.

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 0% and the schema only types id as a string with no description. The description partially compensates by stating the id is a listing id obtained from search_services, which is genuine added meaning, but gives no format or failure semantics for the parameter.

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 resource (one listing) and a specific retrieval scope (full details by id), which an agent can distinguish from search_services and list_categories. It is clear but the verb is nominal ('full details of') rather than an explicit 'retrieve/fetch', so it falls just short of a 5.

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 parenthetical '(from search_services)' tells the agent the id originates from a prior search call, establishing a clear use context. It does not state when not to use it or what to do if the id is unknown, so no explicit alternatives are offered.

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