dex_get_pair

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

No annotations are provided, so the description must fully disclose behavioral traits. It does not state whether the tool is read-only, what happens if a pair is not found, or any permission requirements. This lack of transparency could lead to incorrect expectations.

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 a single concise sentence with no wasted words. However, its brevity sacrifices important details that are necessary for an agent to use the tool correctly. It is efficient but incomplete.

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?

Given the complexity (3 optional parameters, no output schema, no annotations), the description is inadequate. It does not specify expected output, error behavior, or parameter relationships, leaving significant gaps for the agent.

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?

With 0% schema description coverage, the description must add meaning. It hints that 'id' refers to pair_id and 'token contracts' refers to token_a/token_b, but does not clarify required combinations, data types, or constraints (e.g., whether both token_a and token_b are needed together). This is insufficient for proper parameter usage.

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 verb 'get' and the resource 'canonical DEX pair', and specifies identification methods (by id or token contracts). However, it does not differentiate this tool from siblings like dex_list_pairs or dex_get_price, missing an opportunity to clarify when to use this specific tool.

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?

No guidance is provided on when to use this tool versus alternatives such as dex_list_pairs (list all pairs) or dex_get_price (get price). The agent is left uncertain about context and selection without explicit usage hints.

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