Update inventory-related settings

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

With no annotations provided, the description carries the full burden of disclosing behavior. It only states 'update' without mentioning what is modified, whether it replaces or patches settings, any permission requirements, side effects, or return values. This is insufficient for a mutation tool.

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 short sentence, but it merely restates the title in Japanese ('Update inventory-related settings' vs. 'Update inventory-related settings'). It earns no place because it adds no additional information; this is under-specification rather than concise effectiveness.

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 a complex nested 'settings' object, no output schema, and no annotations, the description is grossly incomplete. It does not explain what settings can be updated, how manage_number identifies the item, or what the response looks like. A adequate description would at least list common settings or reference the corresponding getter tool.

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 0%, and the description does not explain the 'settings' object structure or the meaning of 'manage_number'. The schema shows 'settings' as a generic object with additionalProperties, but the description gives no clue about valid keys or values. This leaves the agent completely in the dark about how to construct a correct invocation.

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 '商品の在庫関連設定更新' (Update inventory-related settings) identifies a clear verb and resource, but 'inventory-related settings' is vague and does not distinguish from sibling tools like rms_update_inventory (which updates inventory quantities) or rms_get_inventory_related_settings (which reads settings). Without listing specific settings or scope, it fails to differentiate adequately.

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 provides no guidance on when to use this tool versus alternatives, no prerequisites, and no exclusions. It does not mention that it complements rms_get_inventory_related_settings or that it differs from rms_update_inventory. The agent must infer usage from the name alone.

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