B2B Social to Email

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

With no annotations provided, the description carries the full burden. It states the basic conversion but omits operational traits such as permissions, rate limits, credit costs, verification status, and empty-result behavior.

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 concise sentences and front-loads the main action. The second sentence largely restates the first rather than adding new information, so it is efficient but not perfect.

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?

There is no output schema and no annotations, so the description should explain return values and operational context. It does not describe the output format, failure cases, cost, or verification behavior, leaving the definition incomplete for an enrichment tool.

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 identifies profile_url as a B2B/social profile URL, which adds meaning, but provides no examples, platform restrictions, or format details beyond the schema's URI type.

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 clear verb and resource: find work email addresses from B2B profile URLs. It does not explicitly differentiate itself from sibling tools like find_email or find_personal_email, so it falls 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?

The description implies the use case by mentioning B2B profile URLs and work emails, but gives no explicit when-to-use guidance or alternatives to sibling tools such as find_email, find_personal_email, or email_to_profile.

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