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

With no annotations, the description carries the full burden. It discloses the cost ($0.02 USDC), the network (Base), and the high-level output (APY, TVL, security read). However, it does not state whether this is a read-only operation, what the security read actually returns, or any failure modes or rate limits.

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 two concise sentences. It front-loads the core purpose in the first sentence and adds cost/chain context in the second. No unnecessary words.

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 single-parameter tool, the description gives a reasonable overview of what the tool does and key details like cost and network. However, missing parameter semantics and explicit usage comparison with siblings make it incomplete, especially with no output schema.

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 has one parameter 'pool' with no description, and the tool description never mentions it. With 0% schema description coverage and no additional explanation, the agent has no idea what format 'pool' should take (address, symbol, ID, etc.). This is a critical gap.

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 DeFi pool intelligence including live APY, TVL, and an on-chain security read. The 'pre-deposit' context clarifies its purpose. However, it doesn't explicitly differentiate from sibling tools like defi_pool_deep or defi_pool_top, so it's not fully distinctive.

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 phrase 'pre-deposit intelligence' implies when to use it (before investing into a pool), but there's no explicit guidance on when to choose this over siblings or when not to use it. No alternatives are mentioned.

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