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

No annotations are present, so the description carries the burden. It compensates by stating that the tool 'Returns' information, labeling it 'Decision support only', and disclosing the ladder mechanics, including the default-resets-streak rule. It does not explicitly assert read-only behavior or discuss auth/rate limits, but the get/Returns framing makes the informational nature clear.

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 core behavior is front-loaded and the incentive mechanics are compactly summarized. However, the description includes promotional noise such as '[FREE]', 'invention #4347', and 'Underwritten by SolvScore (URL)', which do not help an agent select or invoke the tool.

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 one-parameter lookup with an output schema, the description covers what is returned, the incentive rules, and the decision-support boundary. The only notable omission is explicit parameter semantics, which keeps it from being fully 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?

The schema has one required parameter, agent_ref, with no description, and schema description coverage is 0%. The tool description never mentions agent_ref, its format, or how to obtain it, leaving the agent to infer it refers to the AI agent being evaluated. This is a real gap because the description does not compensate for the empty schema.

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 explicitly states that the tool returns the repayment incentive ladder, current SolvScore terms, loan history, the 4-rung ladder, and projected next-milestone terms, with concrete mechanics (APR step-downs, credit-limit bumps, streak reset). This clearly distinguishes it from related siblings like underwrite_agent_loan or get_credit_market_stats.

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 when an agent needs its repayment incentive terms and adds 'Decision support only' as a boundary. However, it does not explicitly name when to use this tool over alternatives or provide exclusion criteria, so the guidance remains implicit rather than explicit.

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