v2.1.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It does disclose an important edge case: 'Unregistered agents get trusted: false with a registration CTA.' However, it does not mention permissions, rate limits, or whether the operation is read-only, though 'Single-call verdict' implies a safe read. Missing details on profile info scope and potential errors.
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 primary purpose and followed by return value and edge-case behavior. Every sentence adds value and there is no 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 tool is simple (one parameter, no output schema). The description covers the main function, return contents, and unregistered-agent behavior. It could be more complete by mentioning response format or potential errors, but for this low complexity, it is sufficiently complete for an agent to select and invoke.
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% for wallet_address, which already explains the parameter clearly. The tool description adds no additional meaning to the parameter, so the baseline 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 purpose: 'Single-call trust verdict for any wallet address' and lists specific outputs (score, tier, profile info). It distinguishes itself by emphasizing 'any wallet address' and 'single-call', but does not explicitly compare with sibling tools like team_trust_check or bridge_erc8004_trust_check, so it lacks full sibling differentiation.
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 explicit guidance on when to use this tool versus alternatives. The phrase 'Single-call' hints at a quick lookup, but there are no exclusions or named alternatives, leaving the agent to infer appropriate contexts from the tool name and sibling list.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
