generate_ad_copy

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

With no annotations provided, the description carries full burden and excels. It includes a dedicated 'Behavioral Transparency' section detailing side effects (read-only), authentication, rate limits, error handling, idempotency, and data privacy. No contradictions with missing annotations.

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 well-structured with sections but is somewhat verbose. The 'Behavior' and 'Behavioral Transparency' sections partially overlap, and the 'Args' list could be more concise. It is front-loaded with purpose, but contains redundancy.

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 6 parameters, 0% schema coverage, and an output schema, the description covers behavioral aspects well but fails to explain the output or tailor the generic 'analysis/classification' framing to ad copy generation. The output schema exists, so return details are not required, but a brief output description would enhance completeness.

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%, so the description must compensate. However, each parameter description (e.g., 'The product to analyze or process') is generic and adds no meaningful context beyond the parameter name. For a tool generating ad copy, expected values or constraints are not mentioned.

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 'Generate ad copy for a platform' and expands on behavior, but the 'When to use' section generalizes to 'structured analysis or classification', which slightly conflicts with the tool name. It does not distinguish from siblings like generate_headlines or generate_variants.

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 provides explicit 'When to use' and 'When NOT to use' sections, but does not compare to sibling tools or give specific scenarios for this tool versus alternatives. Guidance is present but generic.

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