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

Annotations already convey that this is a write operation (readOnlyHint=false) and idempotent (idempotentHint=true). The description adds only the note that the request is 'bound' and goes to a dealership, which is a mild additional behavior. No details on side effects, confirmations, or error conditions are provided.

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 one concise, front-loaded sentence with no wasted words. However, the brevity is a trade-off that omits important usage and parameter context, but the sentence itself is well-structured.

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?

Despite having 5 parameters, a nested customer object, and no output schema, the description offers only a one-sentence purpose statement. It does not explain what the tool returns, what constitutes a successful submission, how 'bound' is enforced, or any prerequisites. The description is inadequate for safe and correct invocation.

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% – no parameter descriptions exist. The tool description does not compensate: it fails to explain what 'binding', 'disclosure_text', 'comments', or the customer object structure mean. The agent is left with raw parameter names and validation rules only.

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 clearly states the action ('Submit'), the resource ('shopper's bound contact request'), and the recipient ('named dealership'). It distinguishes itself from sibling tools like lead_prepare by indicating this is the final submission step.

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 provides no guidance on when to use this tool versus alternatives, nor does it mention prerequisites or sequencing (e.g., that lead_prepare might need to run first). The title hints at a confirmation step but the description does not explicitly contextualize it.

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