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

No annotations are provided, so the description carries the full burden. It usefully discloses the score range, included fields, and that there is no cost, but says nothing about preconditions (does the wallet need to be activated?), behavior for unknown wallets, or rate limits/commercial tiering despite marketing it as 'free'.

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?

Three short sentences, front-loaded with the core output, then the included fields, then the cost note. No filler; the only slight waste is that 'FICO-style' is marketing color rather than actionable information.

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 read with no output schema and no annotations, the definition covers what the result contains (score, grade, loyalty tier), which is the main thing. It still lacks error/edge-case behavior and any pointer to bureau_full_report or get_agent_passport for richer data.

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 0% and the single 'wallet' parameter is bare, so the description must compensate. It does partly by specifying 'any XRPL wallet', telling the agent this is an XRPL address rather than an internal ID, but gives no format or example.

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 resource and scope: a 300-850 credit score for an XRPL wallet, with the extra outputs (grade, loyalty tier) named. It is clear what the tool returns, but it never explicitly contrasts itself with the sibling bureau_full_report, so the 'public' vs 'full' distinction is left to inference.

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 word 'Free' plus 'public' hints that this is the lightweight, no-cost alternative to bureau_full_report, but no when-to-use or when-not-to-use statement is made. An agent must infer that it should pick this over the sibling for a quick score check.

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