wow_cross_realm_arbitrage

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

With no annotations provided, the description must convey behavioral traits. It states that the tool 'detects' opportunities and 'returns profit calculations', implying it is a read-only analysis tool. However, it does not disclose whether it modifies any data, requires specific permissions, or handles errors. This is adequate but could be more transparent.

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 just two sentences, conveying the core functionality and return value without any extraneous information. It is front-loaded with the main purpose and efficient in its use of words.

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 5 parameters, 8 sibling tools, and no output schema, the description fails to explain the return format, error handling, or how to interpret the results. It only mentions 'profit calculations after estimated transfer costs', leaving significant gaps for an agent to use the tool effectively.

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 already describes all parameters (80% coverage), so the description adds minimal value beyond naming 'source' and 'target' realms. It does not explain parameter relationships or provide examples. The baseline 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.

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

The description clearly states the verb 'Detect' and the specific resource 'cross-realm arbitrage opportunities', distinguishing it from sibling tools like wow_auction_search (general auction search) and wow_crafting_profit_analyzer (crafting profit). It also mentions the return of profit calculations, which further clarifies its purpose.

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 does not provide any explicit guidance on when to use this tool versus its siblings. There is no mention of prerequisites, scenarios where this tool is appropriate, or when to avoid it. This omission leaves the agent without contextual direction.

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