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 meaningful traits: it is a paid call ($0.005 USDC via x402), it performs direct on-chain reads, and failed lookups are not charged. It omits authorization/rate-limit context, but the payment and settlement semantics are the operationally important details here.

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 sentence is front-loaded and dense with useful content, but the trailing sentence advertising /shop/, /sponsor tips, and /ledger is unrelated to selecting or invoking this tool and dilutes the definition.

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?

With no output schema and no annotations, the description compensates reasonably by enumerating the checks performed and the riskLevel heuristic, plus pricing/settlement terms. What is missing is sibling disambiguation and any indication of what a returned payload looks like beyond the field list.

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?

Only one parameter (mint) and schema coverage is 100%, so the schema already fully documents it as a base58 SPL/Token-2022 mint address. The description adds nothing syntactic or semantic beyond the schema, matching the baseline of 3 for fully-covered parameters.

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+resource ('Solana token safety check') and enumerates exactly what is inspected (mint/freeze authority, Token-2022 extensions, metadata mutability, holder concentration, riskLevel). It does not differentiate itself from the sibling token_check_batch or mint_preflight, so an agent must infer that this is the single-mint variant.

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?

No when-to-use guidance and no exclusions; the agent is never told when to prefer this over mint_preflight or token_check_batch. The only conditional information ('failed lookups are not settled') is billing behavior, not usage guidance.

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