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

With no annotations, the description carries the full behavioral burden and does so thoroughly: it discloses the two-step validation flow, the returned summary/consent line/confirmation token, the post-submission email-link gating before providers see details, and the exact consent meaning. This gives the agent a clear picture of side effects and required user interactions.

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 front-loaded with purpose and uses a clear step-by-step structure appropriate for a complex two-step tool. The verbatim consent quote is lengthy and duplicated from the schema, slightly reducing conciseness.

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 the two-step workflow, consent requirements, lack of annotations, and no output schema, the description is complete: it explains return values, side effects, and the post-submission email verification. An agent has everything needed to invoke it correctly.

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 coverage is 100%, so the schema already documents each parameter, establishing a baseline of 3. The description adds meaning by linking the confirmation token to step 1's output and clarifying that the same answers must be resubmitted, which enriches parameter semantics beyond the schema.

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?

States a specific verb ('Submits') and resource ('enquiry to HVAC Software Picker'), and clarifies it is not a purchase or guaranteed quote. However, it does not explicitly differentiate from sibling tools like compare_options or enquiry_describe, so it falls short of the top score.

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?

Provides explicit step-by-step conditions for when to call (step 1 with answers and consent; step 2 only if the person agrees) and references enquiry_fields for field keys. It does not name alternative tools for the core action, so no explicit alternative routing.

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