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

readOnlyHint=true already declares the safety profile, so the bar is lower; the description adds the upstream endpoint (GET /asset/{id}) and hints at returned attributes. It says nothing about what happens when the id does not exist or what happens with unknown/missing ids.

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 short sentences, zero filler, with the core behavior front-loaded and the API mapping trailing. Every element 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?

For a one-parameter read tool with readOnlyHint, full schema coverage and no output schema, the description is essentially sufficient — it identifies the record, the lookup key, and the main returned fields. Only error/not-found behavior 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 100% and the single `id` parameter is fully documented in the schema, so the baseline of 3 applies. The description's 'by id' adds no format, range, or sourcing guidance beyond the schema's integer/exclusiveMinimum constraints.

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 asset by id') and names the salient returned fields (type, location, status). The singular 'one asset' implicitly distinguishes it from servicetrade_list_assets, but that sibling is never named explicitly.

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 only implied by 'by id' — an agent can infer this is the single-record lookup versus the list tool, but there is no explicit when-to-use, no prerequisite statement, and no named alternative to route against.

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