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

With no annotations, the description clearly states behavioral traits: accepts no input and returns no personal or customer data, implying a read-only, safe operation. It does not contradict annotations (none 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 a single long sentence that front-loads the main purpose. It could be broken into two for clarity but is reasonably concise with no fluff.

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 the tool has no parameters and no output schema, the description lists all returned components, providing a complete picture. It does not mention error behavior or authorization, but these are less critical for a zero-input read 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?

The tool has zero parameters and schema description coverage is 100%. The description adds that it accepts 'no input', which is already implied by the empty schema, so no extra meaning is needed.

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 tool returns 'the official no-purchase evaluation sequence' and lists five specific components (buyer guide, fictional example audit, browser-only calculator, public workflow tests, no-card production trial). This distinguishes it from siblings like get_leadproof_trial or get_leadproof_evidence.

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?

No explicit when-to-use or when-not-to-use guidance is provided. The description implies the tool is for evaluation without purchase, but it does not contrast with sibling tools such as 'audit_lead_workflow' or 'get_leadproof_checkout'.

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