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

With no annotations, the description carries the burden, and it does disclose price ($0.012 USDC), a settlement, and a stateful per-wallet aspect ('since this wallet last called it'). However, it omits the two-step payment flow and any authorization/failure behavior; these are only covered in the schema's parameter description, not the tool description itself.

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?

Two sentences with no filler: the first front-loads the product and price, then lists contents; the second gives a crisp value proposition. Every word earns its place.

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?

The description tells the agent what data areas are included but not the output format or return structure, which matters given there is no output schema. The payment flow is covered in the schema, so an agent can still call it correctly. Overall adequate for a bundled read-oriented data tool, with a notable gap around response shape.

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 already documents the only parameter (payment) thoroughly, including the call-without-it-once flow, giving 100% schema coverage. The description adds no parameter-level meaning beyond the overall price. Baseline 3 is appropriate.

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 identifies the tool as a decision-ready overnight risk brief and enumerates its contents (DEX-vs-CEX spreads, liquidation zones, funding predictions, sentiment, stablecoin health, recorded changes). This maps cleanly onto sibling tools, clearly distinguishing it as a bundle. The lack of an explicit verb is minor since the tool name supplies 'get'.

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 second sentence gives actionable selection criteria: 20% cheaper than buying the five parts separately and one settlement instead of five. This strongly implies using this tool when you want the full set and individual sibling tools when you need only a subset. It does not state exclusions, but the economic logic provides clear guidance.

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