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

Annotations already declare non-read-only, open-world, non-destructive behavior, and the description adds real side-effect context: a team reply arrives as a written quote, no obligation is incurred, and the user gets a confirmation e-mail with a tracking link. This explains the round-trip consequence beyond what the annotations convey. Minor gaps (no auth/rate-limit detail) keep it from 5.

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?

A single front-loaded sentence that leads with the core action before the outcome. It is dense and mostly earns its words, though slightly run-on and could be split for readability.

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 mutating, open-world tool with no output schema, the description explains what happens after invocation (team reply, confirmation e-mail, follow-up link), which is the key missing context. It omits explicit return values or consent handling detail, but with annotations covering safety it is largely complete.

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 only 50%, and the description compensates only weakly: it stresses that 'real contact details' are required, implying name/email/phone must be genuine, but adds no format or meaning for lang, product, or details beyond what the schema already says. Adequate but not compensating fully for the coverage gap.

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 states a specific verb+resource combination — sending a quote request to Denia Print — and distinguishes itself from price-lookup siblings like get_price by implying it initiates a human/team response rather than returning data. It doesn't name a sibling explicitly, so it falls just short of a 5.

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 gives a precondition for use ('Only with the user's consent and their real contact details'), which is useful guidance, but provides no explicit when/when-not or direct comparison to alternatives such as get_price or message_team. Usage context is implied rather than spelled out.

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