Stylus ERC721

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

With no annotations, the description carries full responsibility for behavioral disclosure. It clearly states the output format (Markdown code block) and the lack of disk side-effects, which is valuable. It does not mention potential errors, permissions, or deployment behavior, but for a code generation tool these are the key aspects.

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 two sentences, front-loaded with the main purpose and immediate behavioral details. No wasted words or redundancy.

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?

The description covers the essential aspects: purpose, output format, and side effects. The schema documents parameters thoroughly. The lack of explicit mention of the Stylus/Rust platform is a minor gap, but the tool name provides that context, so the description is substantially complete.

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%, with each parameter (name, burnable, enumerable, info) already explained clearly. The tool description adds no extra meaning to parameters, so the baseline score of 3 is appropriate.

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 states a clear action 'Make a non-fungible token per the ERC-721 standard' and identifies the resource (token). It does not explicitly mention 'Stylus' or 'Rust', so it doesn't differentiate between sibling erc721 tools for Solidity or Cairo, which slightly reduces clarity.

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 is provided on when to use this tool vs alternative ERC-721 generators. The note about returning source code and not writing to disk is behavioral, not usage guidance. There are no explicit when/when-not or alternative recommendations.

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