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

No annotations are provided, leaving the description to cover behavioral traits. It indicates a read operation with prerequisites, but it does not disclose rate limits, data freshness, side effects, or behavior when 'games' parameter is used versus default (ALL).

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 a single sentence that efficiently conveys the tool's function, outputs, and a key prerequisite. No extraneous information.

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 complexity of aggregating across multiple MMOs and the lack of an output schema, the description omits critical details like return format, error handling, pagination, and whether the default is all games or filtered. Incomplete for agent decision-making.

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 low (33%). The description adds value for the overall purpose but does not explain the 'games' filter or 'include_history' parameter. The phrase 'ALL connected MMOs' contradicts the filtering capability, causing confusion.

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 aggregates a player's assets across MMOs, providing net worth, liquidity breakdown, and diversification recommendations. It uses specific terms and distinguishes from sibling tools like mmo_unified_market_search and mmo_economy_dashboard.

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 mentions the prerequisite 'Requires linked accounts' but does not explicitly state when to use this tool versus alternatives or provide when-not scenarios. Usage context is implied but not explicit.

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