get_preview_app_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 behavioral disclosure. While '取得します' (retrieves) implies a read operation, there's no information about authentication requirements, rate limits, error conditions, or what specific 'app settings' are returned. The description doesn't mention whether this affects the preview environment or has any side effects.

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, efficient sentence that communicates the core purpose without any wasted words. It's appropriately sized for a simple retrieval tool and gets straight to the point.

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?

For a tool with no annotations and no output schema, the description is insufficiently complete. It doesn't explain what 'app settings' actually includes, what format the response takes, or any behavioral constraints. Given the complexity of kintone app configuration and the lack of structured metadata, more context is needed.

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?

With 100% schema description coverage, the schema already documents both parameters thoroughly ('app_id' and optional 'lang' with enum values). The description doesn't add any additional parameter context beyond what's in the schema, so it meets the baseline for high schema coverage.

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 ('取得します' - retrieves/get) and the resource ('プレビュー環境のkintoneアプリ設定' - preview environment kintone app settings), making the purpose immediately understandable. However, it doesn't explicitly differentiate from sibling tools like 'get_app_settings' or 'get_preview_form_fields', which would be needed for a perfect score.

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. With many sibling tools in the kintone ecosystem (like 'get_app_settings', 'get_preview_form_fields', 'get_preview_form_layout'), there's no indication of what distinguishes this tool from those similar-sounding alternatives.

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