wowaudit_list_historical_data

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

Annotations provide strong behavioral cues: readOnlyHint, openWorldHint, idempotentHint, destructiveHint=false. The description adds further value by noting the items listed (dungeons, world quests, Vault), which goes beyond annotations. However, it doesn't mention the lack of pagination or potential response size limits, which would be useful but not required given the annotations already assure safety and idempotence.

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 is clear and to the point. It conveys the key purpose and content without any extraneous words. It earns its place.

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 an output schema, the description need not explain return values. With 2 parameters (0 required), strong annotations, and clear purpose, the description is nearly complete. The only minor gap is the lack of mention about pagination or the fact that upstream API does not support it, but the input schema already notes that in the 'limit' description. Overall very sufficient.

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 coverage is 100%, so the baseline is 3. The description does not add any parameter semantics beyond the schema—it doesn't explain how 'limit' affects the output or how 'period' relates to the Blizzard context. Both parameters are well-documented in the schema already, so no deduction, but no added value either.

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 'List roster activity for a Blizzard period' and lists specific content types (completed dungeons, world quests, Great Vault options), which is specific and actionable. However, it does not distinguish this tool from sibling tools like wowaudit_get_character_history or wowaudit_get_loot_history, which might also list similar data, so it's not a 5.

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 when needing roster activity for a period, but provides no guidance on when not to use it or how it compares to alternatives like wowaudit_get_character_history. There's no explicit context about prerequisites (e.g., needing a valid period from wowaudit_get_period) or limitations (e.g., no pagination support). The annotation 'idempotentHint' suggests safe repeated calls, but this is not mentioned.

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