get_defi_news

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

With no annotations provided, the description carries the full burden for behavioral disclosure. It only states the purpose and gives no information about return format, pagination, sorting, freshness, or any caveats. For a news-fetching tool, this is a significant gap.

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 is front-loaded with the core action and resource. Every word earns its place, and there is no redundant information.

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 the tool's simplicity (one optional parameter, no output schema), the minimal description is borderline adequate, but it omits details like what fields are returned, whether results are chronological, or if there are any location/source caveats. The lack of annotations and output schema increases the need for such context.

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 fully documents the single 'limit' parameter with a description and default, so schema coverage is 100%. The tool description does not add any extra parameter semantics, meeting the baseline for adequate schema coverage.

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 tool fetches DeFi-specific news and lists example topics (yield farming, DEXs, lending protocols), which distinguishes it from general crypto news tools like get_crypto_news. However, it does not explicitly differentiate itself from other news siblings beyond the 'DeFi-specific' tag.

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?

The description implies the tool is for DeFi-related news but provides no explicit when-to-use vs alternatives, nor any exclusion guidance. The presence of many sibling news tools means an agent might need more direction, but the 'DeFi-specific' scope gives a basic hint.

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