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

Annotations already declare readOnlyHint=false, destructiveHint=true, and openWorldHint=true, so the write/destructive nature is covered. The description adds nothing beyond that: it never mentions that this is a two-step operation requiring a confirm_id token from a preview call before the write actually executes, which is the single most important behavioral trait here and is only discoverable by reading the schema.

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 front-loaded sentence with no filler or redundancy. It is efficient, though its brevity borders on under-specification rather than disciplined conciseness.

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 destructive, open-world mutation with 40% schema coverage, no output schema, and a non-obvious preview-then-confirm execution model, the description omits everything an agent needs to call it safely. Annotations carry the safety profile, but the confirmation requirement and parameter scoping are missing from the narrative.

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%, so the description should compensate, and it does not: it names only 'SKU' and 'price' and says nothing about currency, account_id scoping, or the confirm_id confirmation flow. All parameter meaning lives in the schema (and two of those descriptions are in Italian), so the description adds no semantic value.

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 states a specific verb and resource ('Update price for a SKU'), so the agent knows exactly what operation is performed. It does not, however, distinguish this single-SKU tool from siblings such as bulk_update_prices or reprice_to_buybox, leaving the agent to infer the boundary.

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?

There is no guidance on when to use this tool versus bulk_update_prices or reprice_to_buybox, no mention of prerequisites, and no hint of the preview/confirm workflow that the schema's confirm_id parameter implies. The agent gets a purpose but no routing information.

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