A4/5.0
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It mentions 'FREE' and 'no payment required' which is good, but does not disclose what the sample contains or any limits. For a simple tool with no parameters, it is adequate but not rich.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is extremely concise: two short sentences that convey the essence without any fluff. Every word earns its place.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness4/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no parameters, no output schema, and low complexity, the description sufficiently communicates the tool's purpose as a free preview. It could mention the output format but is largely complete for its scope.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The tool has no parameters and schema coverage is 100%, so the description has nothing to add. With zero parameters, baseline is 4.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states it is a free sample of live DeFi yield pools, with the verb 'sample' indicating a preview. This effectively distinguishes it from the sibling tool 'defi_yields' which would provide full data.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines3/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description does not explicitly state when to use this tool versus 'defi_yields', but the word 'preview' in the name and 'sample' in the description imply it is for testing or exploration before using the full version.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

A3.7/5.0
Disambiguation4/5
The tools are organized into clear families (chain, crypto, defi, pm, enrich, scan) and each targets a distinct data type. The preview tools are explicitly labeled as free samples, reducing but not eliminating confusion with their paid counterparts. Some overlap exists between chain_wallet and chain_balance, and between enrich_domain and enrich_tech_risk, but descriptions clarify the difference.
Naming Consistency5/5
All tools follow a consistent resource_action pattern using snake_case (chain_balance, crypto_funding, enrich_domain). Preview tools consistently append '_preview' to their paid counterpart. The only minor variation is abbreviations like 'tx', 'pm', 'defi', but these are uniform.
Tool Count3/5
At 22 tools, the server is on the heavy side. The eight preview tools duplicate the functionality of their paid versions and inflate the count, though they serve a legitimate 'try before pay' purpose. The remaining 14 paid tools cover a wide range of risk data, making the count borderline appropriate.
Completeness4/5
The set covers on-chain balances, token security, DeFi yields, crypto prices, funding rates, prediction markets, domain enrichment, tech-risk CVE scanning, and MCP server auditing, which is a comprehensive risk toolkit. Minor gaps exist (e.g., no historical data, no address reputation, no token price by address), but the core workflows are well covered.
