v0.1.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full behavioral burden. It clearly discloses that it fetches and signs only the exact challenge, returns a fixed submit URL and body, and does not submit. It does not cover auth requirements, rate limits, or whether signing alters wallet state.
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?
A single sentence, front-loaded with the tool action and scoped by 'only' and 'without submitting.' Every phrase earns its place; there is no filler.
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?
For a zero-parameter preparation tool with no output schema, the description explains the inputs needed (none) and the return shape (fixed submit URL and body). It does not explain when to choose this over other wallet tools, but otherwise it is sufficient for correct invocation.
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?
There are zero parameters and the schema description coverage is 100%, so the baseline is 4. The description adds no parameter meaning because there are no parameters to describe.
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 specific verb+resource: fetch and sign Voidly's exact seller-registration SIWE challenge, and return the submit URL/body without submitting. It is clearly not a tautology and is distinguishable from generic wallet tools, but it does not explicitly differentiate itself from any sibling by name.
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 implied: use this tool to prepare a Voidly seller-registration submission rather than to submit it. The 'without submitting' clause clarifies a boundary, but no alternative tool is named for the actual submission step and no explicit when-to-use/when-not-to-use guidance is given.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
