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

With no annotations, the description carries the full burden, and it does add one genuinely useful behavioral trait: pay-per-call pricing at $0.001 USDC. However, it says nothing about return contents, error behavior, rate limits, or auth requirements, so the disclosure is only partial.

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?

Three short, front-loaded sentences with no filler; the core purpose and the pricing fact both land early. The per-chain path listing is slightly internal/technical filler for an agent, keeping it from a 5.

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 one-parameter, no-annotation, no-output-schema tool the description is adequate on scope and cost, but it leaves the return shape of 'network health' and the relationship to solana_health undefined, so it is only the minimum viable.

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?

Schema coverage is 100% and the enum plus 'Chain to query' already documents the single parameter, so the baseline is 3. The description maps each enum value to a backing path, which adds minor meaning but not much that helps the agent choose a value.

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?

States a specific verb+resource ('Network health for a chosen chain'), so the agent knows exactly what it retrieves. It does not differentiate from the overlapping sibling solana_health, which appears to be a chain-specific variant of the same capability.

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?

There is no when-to-use or when-not-to-use guidance and no named alternative. The phrase 'for a chosen chain' only weakly implies scope, and the description never tells the agent when to prefer this over the sibling solana_health.

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