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

With no annotations, the description carries the full burden and does disclose two meaningful behavioral traits: the tool is paid ($0.01 USDC fixed via x402) and it enforces a 1–5 mint batch limit. That cost/payment-mechanism disclosure is genuinely useful, though it stops short of describing rate limits, error handling, or what the safety checks actually evaluate.

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?

A single tightly-packed sentence front-loads the purpose, the cost, and the batch bound with no wasted words. Every clause earns its place.

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?

There is no output schema, so the description ideally should describe the return shape; instead it defers via 'same fields as token_check per mint', which is a partial hint but forces the agent to consult the sibling. Combined with no annotations, the definition is adequate for invocation but leaves the result contract underspecified.

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 100% — the schema already documents 'Comma-separated base58 mint addresses (1–5)'. The description's '1–5 mints' and 'same fields as token_check per mint' largely restate that constraint rather than adding syntax or format detail, so the baseline 3 applies.

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 — 'batch Solana token safety checks' — and explicitly scopes it to '1–5 mints'. It distinguishes itself from the sibling token_check by naming it and clarifying that it returns the same per-mint fields, so an agent can tell the batch variant apart from the single-mint tool.

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 'batch' combined with the '1–5 mints' bound implicitly signals when to use this over the single-mint token_check, and the reference to token_check establishes the relationship between the two. However, it never states an explicit when-to-use or when-not-to-use rule (e.g. prefer token_check for a single mint), leaving the routing partly to inference.

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