v1.0.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden but only says 'Analyze' – it doesn't disclose what 'analysis' entails (returned fields, ranking logic, whether it's a read-only operation), nor any rate or auth behavior. Too thin for a no-annotation tool.
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?
A single, front-loaded sentence with no waste. Efficient, though its brevity borders on under-specification rather than ideal conciseness.
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?
No annotations and no output schema mean the description must explain behavior and returns, but it doesn't. Optional-asin/brand tradeoffs and the meaning of 'competitor analysis' output are unaddressed.
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 coverage is 100%, so the schema documents asin, brand, and limit. The description merely echoes 'product or brand' without adding format, relationship, or default behavior beyond what the schema already provides. Baseline 3 applies.
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 verb (Analyze) and resource (competitors), scoped to a product or brand. However, it doesn't differentiate from siblings like smartscout_market_analysis or smartscout_opportunity_finder, leaving the intent somewhat vague relative to the crowded sibling set.
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 when-to-use guidance, no alternatives mentioned, and no exclusions. The description gives no signal about when this should be chosen over market_analysis or opportunity_finder.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
