mmo_meta_trend_analysis

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

No annotations are provided, so the description must fully convey behavior. It suggests a read-only analysis but does not explicitly state read-only nature, authentication needs, rate limits, or whether it modifies data. The description gives a general sense but lacks necessary behavioral details.

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 at three sentences, with the core purpose front-loaded. The second sentence is a question that adds tone but not essential information. Slightly more could be achieved without the question, but it remains efficient.

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 2 simple parameter enums and no output schema, the description provides a good overall context but lacks details on what the response contains, how to interpret results, and does not cover parameter options. It is incomplete for a tool with no other documentation.

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 input schema has 2 parameters with enums but no descriptions, and the description does not mention or explain them. With 0% schema description coverage, the description should compensate but fails to provide any parameter semantics beyond the enum values themselves.

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 it is for cross-game meta trend analysis, specifically identifying items spiking across all MMOs and detecting global patterns. This distinguishes it from sibling tools like mmo_economy_dashboard (likely single-game) or mmo_gold_conversion (specific conversion).

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 global trend analysis but does not explicitly state when to use this tool versus alternatives. It lacks guidance on when not to use it or which specific contexts it is best suited for.

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