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

With no annotations present, the description carries the behavioral load and does so well: it discloses the payment rail (x402 in params._meta['x402/payment']), the price and settlement chain (USDC on Base, eip155:8453), and the transport (GET to a fixed URL). It does not say what happens with invalid or unknown mints, whether partial failures still incur the charge, or how the 10-item cap is enforced.

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?

Every clause is front-loaded and load-bearing: purpose and cap first, cost comparison second, then payment and transport details. No filler or repetition of the tool name.

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?

No output schema and no annotations mean the description is the only documentation, and it explains the payment mechanics thoroughly. However, it never describes the returned risk-score shape (fields, scale, per-mint errors) or the input string format, leaving gaps that matter for a paid batch call.

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% for the single 'mints' parameter, and the description only says it accepts 'up to 10 Solana mints'. Because the schema types it as a plain string, the format (comma-separated list? single mint per call?) is left ambiguous, which is the one detail an agent most needs to call it correctly.

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 ('Risk score for up to 10 Solana mints'), plus the scope limit (10) and the ordering ('sorted worst-first'). An agent can immediately tell this is the batched counterpart to solcheck__risk rather than a single-mint check.

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?

Implies when to use it via 'ONE $0.01 call' and 'Cheapest per-token risk check available here', which steers multi-mint workloads to this tool over repeated single calls. It stops short of an explicit exclusion ('use solcheck__risk for a single mint') or guidance on what to do when more than 10 mints are needed.

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