Set product prices

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

Annotations only provide readOnlyHint=false and destructiveHint=false. The description adds that changes are live immediately, which is a meaningful behavioral disclosure beyond the annotations. However, it does not specify whether existing prices are overwritten or merged for the given product/pricelist.

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 two sentences: first states the purpose concisely, second lists required fields and the production warning. Every sentence earns its place with no redundancy.

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?

The description covers the core purpose, required parameter structure, and production impact. It lacks details on return values or whether the call replaces existing prices, but given the relatively simple schema and no output schema, it is largely complete for an agent to use the tool 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 coverage is 100% with clear descriptions for all three parameters. The description restates the required fields per entry (currency_id, billing_cycle_months, price) but adds no new meaning beyond the schema. Baseline 3 is appropriate.

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 uses a specific verb ('Set/update') and resource ('prices for a product on a specific pricelist'), making the tool's function immediately clear and distinguishing it from sibling read tools like get_product_prices or general product updates like update_product.

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?

The description implies usage context (setting prices on a pricelist) and includes a production warning ('changes are live immediately'), but it does not explicitly mention when to use this tool versus alternatives or provide exclusion criteria. The guidance is implied rather than explicit.

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