wow_price_history

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

No annotations are provided, so the description carries the full burden. It discloses the data source (MEOK Gaming Data Moat) and mentions output contents (averages, volume, volatility), but does not disclose rate limits, authentication needs, or whether the tool is read-only. Moderately 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 two sentences (19 words), front-loaded with the main purpose, and includes supplementary detail about return types and data source. No wasted 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 5 parameters, no output schema, and no annotations, the description adequately explains what the tool returns (time-series with averages, volume, volatility) and the data source. It does not detail the return format further, but the schema covers parameters well. Slightly above adequate.

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 100%, so baseline is 3. The description adds minimal parameter information beyond schema (e.g., hints at granularity via 'daily/hourly' but schema already has enum). No additional semantics for item_id vs item_name or days default.

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 action (retrieve), resource (historical price data for an item on a realm), and what is returned (time-series data with daily/hourly averages, volume trends, volatility metrics). This distinguishes it from sibling tools like wow_auction_search (current auctions) and wow_market_snapshot (snapshot).

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 historical price data but does not explicitly state when to use it versus alternatives, nor does it provide exclusion criteria. The context is clear but lacks explicit guidance.

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