Scored across 2 tools
The two tools are broadly distinct: token_risk is a general pre-trade risk analysis across Solana and Base, while token_security targets Solana-specific mint/freeze and Token-2022 controls. The semantic overlap between 'risk' and 'security' could cause mild confusion, but the descriptions clarify different scopes.
Both tools use the same token_ prefix and underscore-separated noun structure. The naming pattern is perfectly consistent and predictable.
Two tools is minimal and sits at the low end of appropriateness for a specialized paid-analysis server. The count is not absurdly thin given the niche, but the surface feels sparse.
The pair covers general risk screening and a deep Solana control check, which is a reasonable core offering. Minor gaps remain, such as no Base-specific security/control analysis or batch/portfolio checks, but agents can work around these for basic paid risk assessment.

Paid pre-trade token risk analysis. Supports Solana and Base. The HTTP transport returns an x402 challenge before private analysis executes.

| address | Yes | Token mint or contract address on the selected chain. Example Solana: So11111111111111111111111111111111111111112. Example Base: 0x4200000000000000000000000000000000000006. |

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already cover read-only, idempotent, and non-destructive behavior. The description adds meaningful context beyond those annotations by disclosing that the tool is paid, that the HTTP transport returns an x402 challenge before execution, and that the analysis is private. This helps the agent anticipate the payment/auth flow without contradicting the read-only hint.
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, each contributing new information: the paid nature and purpose, chain support, and transport-level challenge behavior. The most important qualifier ('Paid pre-trade') is front-loaded, and there is no redundant repetition of the tool name or schema contents.
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?
Given the output schema is present and the annotations cover safety, the description captures the essential call context: purpose, supported chains, and the payment challenge flow. It does not spell out the exact risk-analysis output fields, but the output schema likely handles that, and the only minor gap is explaining what 'private analysis' means operationally.
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%, and the parameter descriptions already include chain enum values, defaults, and concrete address examples. The description adds no new parameter-level meaning beyond restating chain support, so a baseline score of 3 is appropriate.
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 clearly states the tool performs paid pre-trade token risk analysis and names the supported chains. It does not explicitly distinguish itself from the sibling token_security, so it lacks direct sibling differentiation, but the verb and resource are specific enough for an agent to understand the core purpose.
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 this is used before trading and supports Solana/Base, but it gives no guidance on when to choose this tool instead of token_security. There is no mention of exclusions, alternatives, or conditions under which this tool should not be used.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already provide safety hints (read-only, non-destructive, idempotent). The description adds valuable behavioral context beyond those hints by disclosing that the tool is paid and that its HTTP transport returns an x402 challenge before the private analysis runs. This is important operational behavior not present in annotations.
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?
Two concise sentences with no filler. The first sentence captures purpose and scope, and the second flags the payment/challenge behavior. All included information 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?
With a rich output schema, 100% schema documentation, and safety annotations, the description is nearly complete for invoking the tool correctly. The only notable gap is lack of guidance about how to satisfy the x402 challenge or when to choose the sibling token_risk tool, but the essentials are covered.
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 input schema covers 100% of parameters with descriptions, including the Solana chain constraint and the example mint address. The description adds no additional parameter-level meaning beyond what the schema already provides, so the baseline score of 3 is appropriate.
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 clearly states a specific resource ('Solana token-control analysis') and what it covers ('mint/freeze authority and Token-2022 control risks'). It does not explicitly differentiate from the sibling 'token_risk', but the naming and paid/Solana framing make the purpose reasonably distinct.
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 communicates clear context: this is a paid analysis, Solana-only, and requires handling an x402 challenge before execution. It does not explicitly say when to use this tool instead of token_risk, but the 'Solana only' constraint and payment gate give sufficient usage boundaries.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
