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

With no annotations, the description carries the full disclosure burden, and it does add real context: submissions are routed by email to the practitioners, not a generic inbox. However, it says nothing about confirmation, storage, failure modes, or rate limits, and its claim that the tool 'needs' name, email/phone, and need conflicts with the schema, which marks zero required parameters.

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 short sentences with the purpose front-loaded and no padding. The informal phrasing ('Send us an inquiry') is slightly less precise than it could be, but nothing is wasted.

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?

An output schema exists, so return values need not be explained, and the schema covers all parameters. What is missing is what happens after submission and an accurate statement of constraints, since the description's implied required fields disagree with the schema's zero-required configuration.

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 100%, so the schema already documents all six fields, including the mutually-exclusive email/phone rule and the enumerated lines of work. The description only restates a subset ('name, an email or a phone, and what they need') and none of the optional fields, so it adds nothing beyond schema 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?

States a concrete verb and resource ('Send us an inquiry') plus the delivery mechanism ('reaches the people who do the work, by email'), which is enough to distinguish it from read-oriented siblings like read_page, case_studies, and company. It never names a sibling explicitly, so it falls short of the 5 benchmark.

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?

Usage is implied rather than stated: the agent can infer this is the contact/submission path, and the sentence about required inputs gives a shape for invocation. There is no explicit when-to-use, when-not-to-use, or reference to an alternative sibling tool.

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