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

With no annotations, the description carries the burden but only partially: it discloses the output fields and the read-only nature is implied by 'Browse'. It does not explicitly state that no purchase is made, nor does it mention pagination, authentication, or rate-limit behavior.

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, front-loaded sentence states the verb/resource first, then the return fields, with no filler or repetition of schema details.

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 simple, all-optional-parameter browse tool with a fully documented schema and no output schema, the description's return-field list is sufficient to interpret results. A small gap remains: no explicit statement that this is a non-purchasing, read-only discovery action, and no response-shape detail (e.g., list of objects) beyond the field names.

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%, so the baseline is 3; the description does not add parameter-specific meaning beyond the schema. It mentions 'category' only as a returned field, not as a filter, so no extra semantic burden is placed on the description.

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?

The description uses a specific verb and resource ('Browse available capabilities on the Delvorn marketplace') and lists the exact returned fields, making it easy to distinguish from purchase/quote tools and from get_asset-style lookups. The mention that the returned asset ID is needed for purchasing reinforces its catalog-browsing role.

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 description implies a discovery-before-purchase use case ('asset ID needed for purchasing'), but it does not explicitly say when to choose browse_assets over siblings such as list_asset or get_asset, nor does it state exclusions.

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