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

With no annotations, the description carries the full burden. It mentions returning a quote form and a pitch, but does not disclose side effects (e.g., submitting a lead) or behavioral constraints such as required user information or whether this is a read-only operation.

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 very brief with two sentences and no fluff, front-loaded with the main purpose. While it is concise, the brevity sacrifices necessary details; however, it scores well on efficiency.

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?

For a consultation tool with 3 optional parameters, no annotations, and no output schema, the description is incomplete. It only gives a high-level output and fails to convey parameter usage, expected input, or what happens after submission, which is inadequate for an AI agent to use correctly.

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%, and the tool description does not explain the three parameters (destination, budget_notes, resort_preference) or how they are used. The description fails to compensate, leaving the agent without semantic guidance for the parameters.

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 helps plan a Sandals or Beaches honeymoon and specifies the output (quote form and why Pixie beats booking direct), which distinguishes it from search and deal tools. However, 'Help plan' is somewhat vague about the exact action (e.g., creating a consultation request).

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 guidance is provided on when to use this tool versus sibling tools like search_sandals_resorts, get_sandals_beaches_deals, or request_pixie_quote. The description does not mention prerequisites, alternatives, or exclusions.

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