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

Annotations already declare readOnly=true, idempotent=true, destructive=false and closed-world, so the safety profile is covered. The description adds genuinely useful return-content context (license fields, price, x402 purchase instructions), but says nothing about lookup failure behavior or what happens for unpublished assets.

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 sentence with no filler; the return-content payload is front-loaded and nothing is repeated from the schema or annotations.

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?

With no output schema, the description takes on return-value explanation and does so well for a simple single-parameter lookup. Minor gaps remain around error/empty cases and how to obtain a valid asset id.

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% for the single id parameter, so the description must carry the semantics; it tells us the id references a 'published asset', which is meaningful. However, it does not explain the 16-char hex format or where an id comes from, so the compensation is only partial.

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 concrete verb+resource (get one asset) and enumerates what the response contains (metadata, license fields, price, x402 purchase instructions). The phrase 'one published asset id' implicitly separates it from search_assets and list_sets, though no sibling is named outright.

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: the agent must already hold an id to call this, and 'one published asset id' hints at id-lookup versus search. There is no explicit when-to-use / when-not guidance or reference to search_assets as the discovery alternative.

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