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

With no annotations, the description carries the disclosure burden. It transparently mentions the $0.05 USDC cost on Base mainnet and indicates that the tool flags categories rather than performing mutations. However, it does not discuss auth, rate limits, or failure behavior.

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 succinct sentences: the first states the core functionality, and the second provides the cost. It is front-loaded and contains no unnecessary wording.

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 tool is a simple checker, but with no output schema and no annotations, the description should clarify the return value and edge cases. It lists the flag categories but does not explain what 'colliding' means or describe the output structure. The cost disclosure is useful but not sufficient to make the description fully 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 0%, and the description only indirectly maps 'image paths' to the 'files' parameter and 'SKU roster' to the 'roster' parameter. The optional 'sku_pattern' parameter is completely unexplained, and no deeper parameter semantics are added beyond the property names.

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 ('Match') and clearly identifies the resource (image paths and SKU roster) and the action (flag missing, extra, unknown, or colliding assets). This distinguishes the tool from sibling checker tools, which focus on different domains.

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 the tool is used when you have image paths and a SKU roster to compare, but it never explicitly states when to choose this tool over alternatives or when not to use it. No exclusions or prerequisites are mentioned.

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