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

Annotations already declare read-only, idempotent, non-destructive, closed-world behavior; the description adds important privacy details (email and phone lines removed before reading and never returned) and states that nothing is stored. It also discloses the full set of checks performed, exceeding the annotation coverage without contradiction.

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 purpose and checks are front-loaded, and every sentence carries relevant information about behavior or privacy. The long check list is dense but appropriate and contains no filler.

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 rich annotations and 100% schema coverage, the description is largely complete for how the tool behaves and what it checks. However, there is no output schema and the description does not explain the returned findings or result format, leaving a modest gap for an analysis 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 100%, so the schema already documents all 8 parameters and nested fields. The description restates the text-vs-lines input mode and 8 KB limit but adds little parameter semantics beyond the schema.

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 specific verb and resource: it reads and checks a dealer's out-the-door quote line by line, listing the exact checks. The scope is clear, but it does not explicitly differentiate itself from the closest sibling compare_quotes.

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?

Gives clear context for when to use it: a single dealer quote needs validation against state caps, tax, add-ons, trade offers, and the walk line. It does not state when not to use it or name alternatives such as compare_quotes for multiple quotes.

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