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

No annotations are provided, so the description must carry the burden. It does add context that the catalogue is 'curated' and 'editorially open', implying a maintained, possibly incomplete list. However, it doesn't mention data freshness, pagination, or that it's a read-only operation, leaving some gaps in behavioral disclosure.

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 description is dense but efficient, with two sentences covering purpose, contents, use case, and filtering. The first sentence is long but every clause adds detail. The second and third sentences are purposeful, though the filtering sentence partially repeats schema info. No fluff, but not as crisp as a two-sentence minimalist example.

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?

For a simple catalogue query with no output schema, the description adequately explains what results will contain (fee, addresses, liquidity notes, caveats) and the intended use case. It doesn't mention return format or error conditions, but that's likely unnecessary for a read-only filterable catalogue. Complete enough for an agent to select and invoke correctly.

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%, so baseline is 3. The description reinforces filtering by chain, max fee, or multi-asset support, but it doesn't add meaning beyond what the schema already explains (e.g., max_fee_bps drops providers exceeding the threshold). Description adds no new semantic detail.

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 provides a curated catalogue of specific flash-loan providers (Aave V3, Balancer V2, etc.) with detailed attributes like fees and addresses. It identifies the resource and scope (Ethereum mainnet), distinguishing it from sibling tools that handle agents, borrowers, or health data.

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?

It gives explicit context: 'Helpful for searcher agents picking the cheapest viable provider for a liquidation or arbitrage strategy.' This tells the agent when to use it, though it does not mention exclusions or alternative tools. Lacks explicit 'when-not-to-use' guidance, so not a 5.

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