hedera_transfer_nft

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

No annotations; description says 'unsigned' implying it doesn't execute the transfer, but doesn't explain further behavioral traits like signing requirement, fees, or error handling.

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?

Single sentence is concise but lacks structure; could be more informative without adding length.

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 and 5 parameters, description fails to mention return value (unsigned transaction) or prerequisites, leaving the tool's usage context incomplete.

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 20% and description adds no parameter details beyond the schema; key parameters like tokenId, serial, toAccountId are not explained.

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?

Description clearly states it builds an unsigned NFT transfer for a specific serial between two accounts, distinguishing it from fungible token or HBAR transfer siblings.

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?

No guidance on when to use this tool vs alternatives like hedera_transfer_token or hedera_approve_nft_allowance.

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