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

With no annotations, the description carries the full burden. It discloses the API key requirement and that the feed is 'ranked' by PeepTrend, adding value. But it omits behavioral details like whether it is read-only, how region/language define 'market', or error behavior without a valid key. This is moderate transparency.

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 entire description is one concise sentence that front-loads the main purpose. Every word earns its place; no filler or repetition.

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 three parameters, no output schema, and no annotations, the description is too thin. It does not explain what the feed contains, how the parameters alter results, or how it differs from sibling tools like get_opportunity_detail. This leaves a significant gap for an agent to correctly select and invoke the tool.

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. It only vaguely references 'market' without explaining region/language. It does not mention the 'mode' parameter or its enum values (qualified, steam-only, watchlist). This leaves all three parameters semantically unexplained.

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 uses a specific verb 'Return' and identifies a distinct resource: 'PeepTrend's ranked Steam and YouTube opportunity feed for a market.' This clearly differentiates it from sibling tools like check_gaming_niche or get_opportunity_detail, which focus on individual checks or details.

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 implies usage for retrieving a market feed and states a prerequisite (PeepTrend API key). However, it does not explicitly say when to use this tool over alternatives, nor does it mention any exclusions. It provides clear context but lacks explicit guidance on alternatives.

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