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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds only that the result is the 'full' listing (as opposed to a search-result stub) and where the id comes from; it says nothing about what happens on a missing or invalid id.

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?

A single tight sentence with zero filler, and the key detail (id source) is placed immediately after the purpose. The telegraphic phrasing is at the edge of under-specification but nothing is wasted.

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 lookup with annotations covering safety, this is close to sufficient. However, there is no output schema, so the description carries some burden for describing what the 'full listing' contains, and it only gestures at that.

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 the single 'id' parameter is undocumented in the schema, so the description must carry that meaning. It does partially, by identifying the id as one produced by search_trades, but gives no format or example of the identifier.

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 the specific resource ('One business's full listing') and the lookup key ('by id'), and ties the id's provenance to search_trades, which cleanly separates it from the sibling search tool. It is a noun phrase rather than an explicit verb, but an agent can still tell exactly what it retrieves.

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_trades)' implies the intended workflow: run search_trades first, then fetch details here. There is no explicit statement of when not to use it, no mention of error behavior for unknown ids, and no comparison to quote_status or request_quotes.

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