defi_get_chain_dex_volume

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

With no annotations provided, the description carries the full burden of behavioral disclosure, but it only states that it 'gets' data. It does not disclose whether the tool returns 24h volume, historical data, units (USD, token amounts), supported chain formats, or any API limitations. This is a significant gap for a tool that might involve network calls 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?

The description is a single concise sentence that immediately conveys the tool's purpose. It is front-loaded with the action and object, contains no filler, and is appropriately sized for the tool's simplicity.

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?

The description is minimally adequate for a one-parameter read-only tool, but it lacks important context such as what the 'volume data' includes (e.g., time period, currency, metric type), whether there are any prerequisites, or what the response structure looks like. Given that there is no output schema, the description should provide more detail about the return value to be fully complete.

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?

The input schema has 100% coverage with a single 'chain' parameter described as 'Chain name'. The description adds no additional meaning beyond what the schema provides, so the baseline score of 3 applies. The parameter is simple and self-explanatory, so no further elaboration is strictly necessary.

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', the resource 'DEX volume data', and the scope 'for a specific blockchain'. This distinguishes it from sibling tools like defi_get_dex_volume (which likely covers all chains) and defi_get_dex_protocol_volume (which is protocol-specific), so an agent can easily select this tool for chain-level DEX volume queries.

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 defi_get_dex_volume or defi_get_dex_protocol_volume. The description simply states what it does without any context on preferred use cases, exclusions, or sibling comparisons. This leaves the agent to infer usage from the name alone.

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