Behavior3/5

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

With no annotations, the description must disclose behavioral traits. It partially does by listing the types of data returned (top movers, trending items, etc.), indicating it's a read-only operation. However, it does not discuss limitations (e.g., rate limits, real-time vs cached data) or any side effects, leaving some ambiguity.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two sentences, front-loaded with the core purpose, and uses an effective analogy. Every word adds value with no redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description adequately covers the tool's purpose and outputs for a simple tool with three parameters. However, the lack of an output schema means the description should specify the return format more precisely (e.g., array of objects, fields included). It is close to complete but could be slightly more explicit.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema provides descriptions for all three parameters with 100% coverage. The description adds a metaphor but no additional semantic value beyond what the schema already conveys. Baseline score of 3 is appropriate since the schema does the heavy lifting.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: 'Get a complete market snapshot for a realm' and lists specific outputs like top movers, trending items, price spikes, volume anomalies. It distinguishes from sibling tools (e.g., wow_auction_search, wow_price_history) by framing it as a broad market overview akin to a stock ticker.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage via the metaphor 'like a stock market ticker for Azeroth', suggesting it's for quick, broad market insights. However, it lacks explicit guidance on when to use this tool versus alternatives (e.g., for detailed item searches or price history) and does not mention when not to use it.

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