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

No annotations are provided, so the description carries the behavioral disclosure burden. It does communicate that the tool generates a draft and is pay-per-use at 8.0 USDC on Base, which is useful. It lacks details about output format, side effects, or failure behavior, but the core generative and cost behavior is present.

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 three short, front-loaded segments: target and purpose, input semantics, and pricing. There is no filler, and every segment adds information relevant to invoking the tool.

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 generation tool, the description covers the purpose, what to pass as input, and the cost, so an agent can make a valid call. There is no output schema and some ambiguity about the exact desired structure of 'requirements', which keeps it just below a perfect score.

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 schema only describes 'input' as 'service input', which is generic. The description adds meaningful semantics by stating 'input=requirements', telling the agent exactly what kind of string to supply.

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 uses the specific verb 'draft' with the concrete resource 'full commercial proposal/RFP response', making the tool's action immediately clear. The 'commercial' qualifier also helps distinguish it from sibling tools like 'grant-proposal', 'business-plan', and 'contract-draft'.

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?

Usage is implied: the tool is for SMBs that need a commercial proposal or RFP response from input requirements. However, it does not explicitly state when not to use it or name which sibling tools to choose instead, such as grant-proposal or business-plan.

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