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

With no annotations present, the description carries the full burden and does it well: it discloses that the quote is binding, the quote_id is valid for 15 minutes, no execution occurs, no credits are consumed, and an API key is required via X-API-Key or Authorization headers. This lets an agent predict side effects and prerequisites accurately.

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 sentences deliver the action, the product definition, the return contract, the expiry window, the no-side-effect guarantee, the follow-up step, the credit behavior, and the auth requirement. Information is front-loaded with no filler or repeated schema content.

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 quote request with no input parameters and no output schema, the description covers everything an agent needs: what is returned (USD price and quote_id), the validity window, the side-effect-free nature, the next step via execute_quote, the credit implications, and required authentication. Nothing essential is missing.

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 is empty with additionalProperties allowed, so there are no parameter names or formats for the description to clarify. The baseline for a zero-parameter tool is 4, and the description appropriately focuses on the output and workflow rather than parameter details.

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 opens with a specific verb and resource: 'Request a FREE commercial quote for: Vegetation Health Index', then defines the product as 'NDVI-based vegetation health and stress index'. It clearly separates this quoting operation from execution by naming execute_quote, so the tool is not confused with its siblings.

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?

It explicitly tells the agent to use this tool for obtaining a quote and to call execute_quote with the returned quote_id when execution is actually wanted, including the fact that execution consumes prepaid credits. It does not explicitly contrast this quote tool with the many other quote_* siblings, but the resource name and NDVI descriptor supply that context.

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