analyze_competition

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

No annotations are provided, so the description carries the full burden for behavioral disclosure. It explains the analysis outputs and the optional marketplace scope, but does not disclose data sources, side effects, or whether it's a read-only operation. Since it's an analysis tool, the lack of side effects is implied but not explicit.

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 concise and well-structured: a one-sentence summary followed by a clean Args list. Every sentence adds value, and it is appropriately sized for a two-parameter tool.

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 simple tool with two params and no output schema, the description covers the essential aspects: what it does and what the parameters mean. It lists the analysis dimensions (count, pricing, saturation, gaps), providing a good sense of the output. It could mention limitations or data sources but is largely 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?

The schema description coverage is 0%, but the tool description provides clear semantics for both parameters ('niche: The niche to analyze', 'marketplace: Optional marketplace to scope to'). This fully compensates for the missing schema descriptions.

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 clearly states the tool's purpose with a specific verb ('Analyze') and resource ('competitive landscape'), and lists the exact outputs (competitor count, pricing, saturation, gaps). It distinguishes itself from sibling tools like research_market or find_trending_niches by focusing on competition analysis.

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 gives clear context: it analyzes the competitive landscape for a niche, with optional marketplace scoping. It implies when to use it (when competition analysis is needed) but does not explicitly mention alternatives or when-not-to-use. The clarity of the context earns a 4.

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