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

The description fully discloses side effects: emailing the visitor, notifying Marian, filing the inquiry, and refusing if the hard gate is unmet. It also reveals workflow constraints such as only collecting name/email at this step and treating ELC membership as a parting gift, not a condition. This adds substantial context beyond the sparse annotations.

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 dense but purposeful, with each sentence carrying essential workflow or gate information. It is front-loaded with the tool's unique role, though the single block of directives could be better structured for quick scanning.

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 16 parameters and no output schema, the description provides strong workflow context: prerequisites, refusal behavior, post-success actions, and optional follow-ups. It does not clarify all parameter meanings or the exact refusal response, but for invoking the tool correctly the critical path is well covered.

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 only 50%, so the description must compensate, and it does explain the critical price_agreed gate and name/email roles. However, many parameters such as focus_area_ids, success_definition, offer_id, and role_band receive no additional semantic context beyond their names or schema hints.

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 action sequence: emails a formal itemized offer with a claim code, notifies Marian, and files the inquiry. It also explicitly brands itself as 'The ONLY tool' that collects contact details and concludes the 16-minute promise, clearly distinguishing it from sibling tools.

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 gives explicit when-to-use instructions: it is the terminal step after price agreement, with a hard gate requiring price_agreed=true. It also tells the agent when not to collect details ('never earlier') and what to do after success, including the booking link, ELC membership offer, and optional one ask.

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