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

With no annotations, the description carries the burden and does well: it discloses that no execution occurs, no credits are consumed, returns a binding price with a 15-minute validity, and requires an API key. It could add error behavior or rate limits, but the essential behavioral contract is clearly communicated.

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 four sentences and front-loads the core purpose ('Request a FREE commercial quote'). It packs necessary information (price, validity, no execution, credits, next step, auth) without excess. Minor redundancy ('Rapid... for a region' could be tightened) but overall efficient.

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 is thorough about the quote behavior, validity, next step, and authentication. However, it lacks any specification of required input (e.g., how to define the region), which is a critical gap given the schema has zero parameters and no output schema. An agent cannot reliably invoke the tool without knowing how to pass the region.

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 are 0 parameters in the schema, so baseline is 4. However, the description says 'for a region' but provides no way to specify that region, and the input schema is empty (additionalProperties true, but no named parameters). The description therefore hints at an implicit input without explaining how to provide it, falling short of the baseline.

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 explicitly states 'Request a FREE commercial quote for: Deforestation Risk Score' with a clear verb and resource. It also distinguishes itself from the many sibling quote_* tools by naming the specific risk type, and from execute_quote by noting this is only a quote, not execution.

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 description clearly indicates when to use execute_quote next ('Use execute_quote with the quote_id to run it') and clarifies that this quote step consumes no credits versus execution. It does not explicitly state when not to use this tool, but the name and context provide sufficient differentiation. The API key requirement is also stated.

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