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

Without annotations, the description carries full responsibility. It discloses the cost ($0.001 USDC/query) and the return fields (price, volume, liquidity), which adds behavioral context. However, it does not mention failure modes, symbol format expectations, or any side effects, leaving gaps.

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, front-loaded with the core purpose and followed by return fields and cost. Every sentence adds value with no unnecessary detail.

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 tool with one parameter and an output schema, the description is fairly complete. It states the cost and return fields, which are essential for usage, and the output schema covers return structure. It lacks some operational context like error handling, but it is adequate for a straightforward query tool.

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. The single parameter 'symbol' is only vaguely referenced as 'a token,' which adds little beyond the parameter name itself. It does not clarify the expected format (e.g., ticker symbol vs. full name) or any constraints.

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 gets DEX pair data for a token across exchanges, specifying the resource (DEX pairs) and the verb (get). It also distinguishes from sibling tools like get_quote or search_token by focusing on DEX pair data with price, volume, and liquidity.

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 usage for DEX pair data but provides no explicit guidance on when to use it versus alternatives like get_quote or search_token. It does not mention any exclusions or prerequisites, so usage context is only implied.

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