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

There are no annotations, so the description carries the full burden. It clearly discloses the SAFE / NOT SAFE verdict, country-level results, concrete fixes, and supported local image formats. It avoids claiming mutation, and 'Analyze' implies a read-only operation, though it does not explicitly address side effects, failures, or required permissions.

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 efficiently structured: a one-sentence purpose, a concise return summary, and a clear Args section. Every sentence adds necessary information, and there is no filler or repetition of schema fields.

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 two-parameter tool with an output schema, the description covers the core requirements: purpose, return value, input path restrictions, optional countries, and default behavior. It is nearly complete, but it does not mention alternatives or edge cases such as unsupported file types or failure behavior.

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%, but the description compensates fully. It explains that image_path must be a local PNG, JPEG, or WebP image, and describes the countries parameter as an optional comma-separated list with an example and a documented default of top GDP markets.

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 and resource: 'Analyze an image for cultural-sensitivity issues across markets before launch.' This is clear and distinguishes the tool from OCR or translation siblings by its focus on cultural-sensitivity checking, though it does not explicitly name or contrast sibling tools.

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 phrase 'before launch' implies a pre-flight review use case, and the optional countries parameter suggests market-specific checks. However, the description does not state when to use this tool instead of related tools like localize_image or extract_image_text, nor does it provide any exclusion criteria.

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