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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so the safety and external-data profile is covered. The description adds the useful detail that data is real-time and lists the metrics surfaced, but it says nothing about what happens with an ambiguous or empty query, how many pairs are returned, 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?

A single compact sentence that leads with the value proposition and metric list, with no filler. It is arguably too terse rather than too long, but nothing wasteful is present.

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?

With no output schema, the description does useful work by enumerating the returned metrics, but it omits the response structure beyond that and gives no guidance on the all-optional parameter set. For a three-parameter tool whose required set is empty, an agent cannot determine what a no-argument call would do.

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 100%, with all three parameters documented with examples, so the schema carries the parameter burden. The description adds no additional meaning about how query, chain_id, and token_address interact or which takes precedence, so the baseline 3 applies.

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 names a specific data resource (DEX liquidity, price, pair volume, market cap) and a specific source (DexScreener), so an agent can tell it retrieves token market data. The verb is vague ('analytics') and the tool name suggests an 'audit', but nothing states what the audit actually consists of, and no sibling tool is differentiated.

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?

There is no guidance on when to use this tool versus alternatives, and no explanation of which of the three optional parameters to supply or in what combination. An agent must infer that it is a token lookup by symbol, chain, or address without any stated condition selecting one over another.

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