run_walmart_product

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

No annotations are provided, so the description carries full behavioral burden. It usefully discloses cost ('Flat 5 points per successful run'), which is a valuable behavioral trait beyond structured data, but it omits explicit read-only confirmation, error behavior, and any other operational constraints.

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?

Two sentences with zero waste. The purpose and returned fields are front-loaded, followed by a concise cost note that earns its place by informing invocation budgeting.

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 simple one-parameter read tool with no output schema or annotations, the description covers what is returned (brand, price, rating, specifications) and how to invoke it. It could be slightly richer on failure modes or return format, but it is largely 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 the schema already fully documents the single 'item' parameter including that it accepts a URL. The description adds no further parameter meaning beyond reinforcing 'by item ID', so the 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?

States a specific verb (Get), resource (full Walmart product details), and the key input selector (by item ID). The phrase 'by item ID' distinguishes it from search-oriented siblings like run_walmart_product_search, making the purpose unambiguous.

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?

Implies usage when you have an item ID, but never explicitly says when to choose this tool over run_walmart_product_search or run_walmart_product_reviews. No alternatives or exclusions are named.

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