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

No annotations are provided, so the description carries the full behavioral burden. It discloses the return fields and even flags a useful quirk (productUrl is a full storefront URL to use directly), but it does not state whether this is a read-only operation, rate limits, whether it spans all connected stores by default, or pagination behavior despite the schema mentioning _pagination.hasMore.

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 front-loaded with the core purpose, then lists return fields, then usage scenarios. It is one dense sentence plus a return-value list plus a usage sentence. It is slightly over-packed in the return field enumeration, but there is no wasted text.

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 read-only tool with a 3-parameter schema and no output schema, the description is adequate but incomplete. It covers return fields and usage well, but without annotations it should have disclosed read-only nature, whether the operation mutates anything, and pagination behavior. The mention of _pagination.hasMore in the schema is a hint, but the description does not connect it.

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 baseline is 3. The description does not add syntax or constraints beyond what the schema provides for limit, store, or _offset. It does mention a default of 20 for limit and 'omit to query all connected stores' for store, but these are already in the schema descriptions.

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 (Get) and resource (product catalog) and enumerates the exact data dimensions returned: inventory levels, pricing, cost, margins, status, SEO metadata. This is specific enough to distinguish it from get_products_by_channel, get_product_analytics, and get_top_products, though the distinction from get_inventory is somewhat blurred by the overlapping inventory dimension.

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?

It explicitly lists the questions the tool answers: 'products, pricing, profitability, cost price, stock levels, or SEO/meta tags.' This gives the agent clear trigger conditions for selecting this tool over siblings without guessing.

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