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

Annotations indicate destructive and non-idempotent behavior, and the description adds that payment requires explicit wallet authorization and human review is needed. However, it doesn't detail what side effects or destructive actions occur beyond payment, leaving some ambiguity.

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 two sentences with the primary purpose front-loaded, followed by essential caveats about cost and review. Every sentence adds value with no waste.

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?

Given no output schema and many undocumented parameters, the description lacks essential details such as return format, meaning of payment fields, and side effects. It provides a high-level summary but is insufficient for an agent to fully understand invocation expectations.

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?

Schema description coverage is 0%, so the description must compensate. It mentions 'dimensions' and 'product details' which hint at parameters like door_width_in, but it fails to explain payment_signature, result_expires, idempotency_key, or other fields. This leaves many parameters undocumented.

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 clearly states the tool returns a door/swing/SlideDrive configuration and price range from dimensions and product details. This distinguishes it from the many content-generation siblings, though it could be more explicit about what 'product details' entails.

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 mentions the tool is a free preliminary estimate requiring human review, which gives context on when to use it, but it doesn't explicitly compare against alternatives or state when not to use it. The guidance is implicit rather than explicit.

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