get_defi_health

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

With no annotations provided, the description carries the full burden. It adequately describes the conceptual output (TVL trends, health scores) substituting for the missing output schema, but lacks operational details like data sources, caching behavior, or freshness of data.

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?

Single sentence with efficient colon structure. Front-loaded purpose ('Assess DeFi ecosystem health') followed by specific metric enumeration. No redundant words.

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?

Appropriately compensates for missing output schema by enumerating expected return data (TVL, revenue trends, concentration risk). For a zero-parameter read-only tool, this provides sufficient context, though data source or latency notes would improve it.

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?

Input schema contains zero parameters. Per scoring guidelines, zero parameters warrants a baseline score of 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?

Clear verb ('Assess') and resource ('DeFi ecosystem health') with specific output metrics listed (TVL, health score, concentration risk). Implicitly distinguishes from siblings like get_asset_context or get_chain_context by focusing on ecosystem-wide DeFi metrics, though lacks explicit comparison.

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?

Lists what data is returned but provides no guidance on when to use this versus alternatives like get_chain_context or get_macro_context. No prerequisites or conditions mentioned.

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