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

With no annotations, the description carries the full burden of behavioral disclosure. It adds useful context about the pricing model (constant product, virtual reserves) and a fixed price hint, but it does not explicitly state that this is a read-only quote that does not execute a trade, nor does it mention any edge cases, fees, or rate-limit behavior.

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 short and front-loaded, but the final fragment '$0.001 USDC' is ambiguous and unexplained, and the brevity comes at the cost of missing essential guidance. It is concise but not sufficiently structured or informative.

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?

Although an output schema exists, the tool has 5 parameters with 0% schema description coverage and no annotations. The description fails to cover parameter meanings, usage routing, or behavioral caveats, making it incomplete for an agent to invoke the tool correctly without additional inference.

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 description coverage is 0%, so the description must compensate, but it does not explain any of the five parameters. Terms like 'virtual reserves' loosely relate to quote_reserves and token_reserves, but amount_in, fee_bps, and payment are entirely undocumented, leaving the agent to guess their roles.

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 identifies the tool as a bonding-curve BUY quote using constant product and virtual reserves, and the BUY keyword distinguishes it from the sibling quote_sell. However, it does not explicitly state what the quote returns (e.g., amount out, price impact), leaving a small gap in purpose specificity.

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?

Usage is implied by the wording 'BUY quote' and the presence of quote_sell among siblings, but there is no explicit guidance on when to use this tool versus alternatives, nor any conditions such as 'use only for buy-side quotes'. No when-not-to-use advice is provided.

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