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

With no annotations, the description carries the full burden and does well: it discloses the verdict thresholds (WELL_FUNDED >=10x, SOLVENT >=1x, THIN <1x), the UNBACKED and PRICE_UNKNOWN cases, the honest-404 behavior for unreadable files, and that the score derives from measured float and real credit. It omits auth, rate-limit, or caching behavior, keeping it short of a 5.

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?

Front-loaded with the use case, followed by inputs, return values, and the verdict enum. Every sentence carries information, though listing all five verdicts plus the provider blurb adds some density beyond what is strictly needed for selection.

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 two-parameter query tool, all the information an agent needs is present: when to call it, what to pass, and what it returns. An output schema exists, but the description's verdict/threshold detail usefully reinforces interpretation without being required.

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 0%, so the description must compensate, and it largely does: it defines 'agent' as an agent name/id or a 0x Base L2 wallet address and 'price' as an optional USDC-per-query value that overrides the known-product registry. Format guidance is strong, though it does not clarify accepted name formats or units beyond USDC.

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 (pre-flight solvency check) and a clear frame of use (before paying a counterparty). It is readily distinguished from siblings like get_agent_credit_score because it names the concrete output (liquid/price ratio and verdict), not generic credit scoring.

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 opening clause tells the agent exactly when to reach for this tool (pre-flight, before paying an agent) and the inputs it accepts. It stops short of naming alternatives or exclusions such as get_agent_credit_score, so it is clear context without explicit routing.

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