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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds valuable behavioral context beyond annotations: it does not upload files and does not need a wallet, which helps an agent understand side effects and authentication expectations.

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?

Three short sentences with zero waste, front-loading what the tool does. The additional notes about published figures and lack of wallet/file upload are relevant and proportionate.

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 five parameters, 0% schema description coverage, and no output schema, the description leaves too much unspecified. It covers the high-level purpose and safety context but does not explain what the quote output contains or what most input parameters mean, making correct invocation harder.

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%, so the description must compensate, but it only vaguely mentions pictures and an optional traits spreadsheet. It does not explain supply, mintPriceSol, collectionName, or how the images array fields are used, leaving most parameter meaning undocumented.

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: quotes the SOL cost of an NFTm launch from pictures and an optional traits spreadsheet. It clearly distinguishes itself from the sibling nftm_launch_collection, which performs the actual launch rather than estimating cost.

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 usage for cost estimation before launching, but does not explicitly say when to use this tool versus nftm_launch_collection. It provides useful context that it does not upload files and does not need a wallet, but no explicit alternatives or exclusions are given.

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