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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the safety profile is covered. However, the description adds no behavioral context beyond 'update'—it does not mention the two-step preview/confirm workflow implied by the confirm_id parameter, nor auth requirements or reversibility.

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?

A single short sentence with no waste and front-loaded purpose, but it is too thin for the tool's complexity. It is concise to a fault, omitting necessary structure for a destructive mutation with a confirmation flow.

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 destructive annotation, the confirm_id workflow, 5 parameters with low schema coverage, and no output schema, the description is severely incomplete. It gives only the bare purpose and leaves critical operational details to be discovered elsewhere.

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 40%, and the description provides no parameter semantics at all. It does not clarify currency, account_id, or the confirm_id preview process; only the intuitive sku/price pair is hinted at by the phrase 'for a SKU'.

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 basic verb+resource ('Update price for a SKU'), but does not differentiate from siblings like bulk_update_prices or reprice_to_buybox. The scope is minimal and no distinguishing detail is offered.

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 guidance, prerequisites, or alternatives. The agent must infer that this is for a single SKU update versus bulk operations, with no exclusions or routing hints.

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