defi_get_dex_volume

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

With no annotations, the description carries the full burden of behavioral disclosure. It does not mention whether the tool is read-only, what granularity or time range the volume overview covers, or what specific metrics are included. The term 'overview' is undefined, leaving the agent guessing about output characteristics.

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, front-loaded sentence that directly states the tool's function without any filler. Every word adds value, making it highly concise and well-structured.

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, parameterless read tool, the description is adequate but leaves gaps. Without an output schema, it doesn't explain what the 'overview' contains (e.g., metrics, time range, aggregation level). It gives the essential intent but not enough detail to fully set expectations 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?

The tool has zero parameters, so the schema provides complete coverage (vacuously). No parameter explanations are needed, and the description correctly focuses on the output rather than inputs. Baseline for 0 params is 4.

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 a specific verb ('Get'), resource ('DEX trading volume overview'), and scope ('across all protocols'). This distinguishes it from siblings like defi_get_chain_dex_volume and defi_get_dex_protocol_volume by emphasizing the aggregate, protocol-wide view.

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_chain_dex_volume or defi_get_dex_protocol_volume. The description merely states what it does without any contextual pointers or exclusions.

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