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

With no annotations, the description carries the full behavioral burden, and it does disclose a genuine operational trait: per-call pricing of $1.50 paid via x402/USDC on Base, which tells the agent this is a metered, crypto-paid service. However, it says nothing about output behavior, latency, or result format, so the disclosure is 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?

Two tight sentences with the purpose front-loaded before the pricing note. No filler, though the pricing detail could arguably be relegated to metadata.

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 simple one-parameter AI service with no output schema, the description covers what it is and its cost basis. It does not convey what kind of negotiation output to expect or any constraints, leaving a modest but real gap.

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 is a single 'prompt' parameter and schema coverage is 100%, so the schema already documents it fully. The description adds no syntax, format, or example beyond what the schema provides, matching the baseline 3 for high 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 names a specific domain resource ('negotiation assistant and strategy advisor'), which lets an agent distinguish it from generalist siblings like ai_consultation or chatbot. It lacks a concrete verb (advise/generate/analyze), so it stops short of a 5, but the purpose is unambiguous.

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 guidance, no exclusions, and no mention of alternatives such as ai_consultation. An agent must infer that this is for negotiation-related prompts only.

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