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

The description discloses key behavioral traits: payment of 0.618 USDC via x402, permanent public registration of the name, and the optional tx_hash parameter indicating a two-step workflow. No annotations are provided, so the description carries the full burden, and it does so adequately.

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?

The description is a single, well-structured sentence that front-loads the key concept and includes essential details (price, wallet address via x402) in parentheses. No wasted words.

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?

While the description explains the workflow adequately, it lacks explicit mention of the tool's output or return value. For a two-step process (get instructions then submit tx_hash), the expected result after each step is not described. This is a gap given the absence of an output schema.

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 100%, so the schema already documents parameters. The description adds value by explaining the workflow (omit tx_hash to get payment instructions), which ties the parameters together and provides context beyond the schema.

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 clearly states the tool's purpose: dedicating a free NFT without ownership, paying directly to the artist, and linking the user's name permanently. It distinguishes from the sibling 'nft_dedicar' by explicitly noting 'sem precisares de possuir o NFT'.

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?

It provides clear context for when to use the tool (when you don't own the NFT) and outlines the steps. However, it does not explicitly list alternatives or when not to use it, though the sibling name 'nft_dedicar' implies the alternative for owners.

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