get_defi_tvl

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

No annotations exist, so the description must fully disclose behavior. It only states 'Get', implying a read operation, but provides no details on data freshness, scope, pagination, or limits. The agent learns little beyond the tool's basic function.

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 short sentence, which is concise but may be under-specified. It could be slightly more informative without losing conciseness, e.g., specifying the data source.

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 no output schema and no parameters, the description is minimal. It lacks context about what 'DeFi Total Value Locked data' entails, whether it's current or historical, and how to interpret the result. This is insufficient for an agent to fully understand the tool's capabilities.

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?

There are zero parameters, and schema coverage is 100%. According to guidelines, baseline is 4. The description adds no parameter info, but none is needed since no parameters exist.

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 'Get DeFi Total Value Locked data', which is a specific verb and resource. It clearly identifies what the tool does, though it could specify scope (e.g., which blockchain). No sibling tool directly competes, so differentiation is not critical.

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 on when or why to use this tool versus alternatives. While no sibling seems directly related, context about use cases (e.g., fetching aggregate TVL for analysis) is missing, leaving the agent without decision support.

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