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

No annotations are provided, so the description must convey behavior. It describes the output comprehensively but does not mention side effects (likely none), authorization needs, rate limits, or error scenarios. This is adequate for a read-only tool but lacks full transparency.

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 a single sentence that front-loads the primary action and then lists outputs concisely. It is efficient without unnecessary words. Slightly longer due to detail, but still well-structured.

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 4 parameters and no output schema, the description covers the returned fields well and references a sibling tool (hd_search) for input. However, it lacks information on error handling (e.g., invalid SKU) or any prerequisites beyond the SKU. This is adequate but could be more complete.

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 each parameter is already documented. The description adds value by providing usage context (e.g., SKU from hd_search, postal code overrides storeId, default storeId). This enhances comprehension beyond the schema alone.

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 clearly states the action ('Fetch'), the resource ('full product card for a Home Depot Canada SKU'), and details the returned fields. It distinguishes from sibling tools like hd_search (which is for searching) and hd_store_availability (likely for specific availability).

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 use after obtaining a SKU, especially via the sku parameter example 'from hd_search results'. However, it does not explicitly state when to use this tool vs alternatives, nor when not to use it. More explicit guidance would improve selection accuracy.

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