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

No annotations are provided, so the description carries the full burden. It usefully discloses the data source (DEXScreener) and a per-call cost ($0.001 USDC), which are important behavioral traits not in the schema. However, it omits other behavioral details such as rate limits, exact vs. fuzzy matching, or what happens on no results.

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?

Three short sentences, all front-loaded and informative. The cost is stated last but clearly, and no sentence is wasted.

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 one-parameter search tool with no output schema, the description covers purpose, return fields, and cost. It could be slightly more complete by hinting at matching behavior or result limits, but it is sufficient for an agent to call it 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%, and the sole parameter is already fully documented in the schema. The description repeats the same semantics ('by name, symbol, or address') without adding extra syntax or format guidance, so the baseline of 3 is appropriate.

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 states a specific verb ('Search') and resource ('DEXScreener for any token or pair') and clarifies that it returns price, volume, liquidity, and pair info across all DEXes. It distinguishes itself from single-purpose siblings like token_price and dex_liquidity by being a cross-DEX search, though it does not explicitly name alternatives.

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: search for a token or pair by name, symbol, or address to get aggregated data. There is no explicit guidance on when to choose this over siblings such as pair_data, token_metadata, or token_price, and no exclusions are stated.

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