compare_with_competitors

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

No annotations are provided, so the description must disclose behavioral traits. It only says 'compare' without indicating whether it's read-only, requires permissions, or what side effects occur. The existence of an output schema is not leveraged to explain return 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 single-sentence description is concise, but it sacrifices necessary detail. It could be restructured to front-load critical information while only slightly expanding length.

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 the tool has 4 parameters and no parameter descriptions, and the output schema exists but is undocumented, the description is incomplete. Agents lack information to correctly invoke the tool or interpret results.

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%, meaning no parameter descriptions exist in the schema. The tool description also fails to explain any of the four parameters (my_asin, keywords, marketplace, max_results), adding no semantic value.

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 the verb 'compare' and resource 'your product vs competitors', but it's vague about what aspects are compared. Sibling tools like 'analyze_competitor_prices' and 'get_competitive_pricing' overlap in purpose, so the description fails to distinguish this tool's specific functionality.

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?

No guidance is provided on when to use this tool versus sibling tools. There is no mention of exclusions, prerequisites, or alternative tools, leaving the agent to infer usage context entirely.

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