cloud_storage_get_bucket_location

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the tool 'Get[s] the region' and describes a default bucket behavior, but lacks details on permissions required, error handling (e.g., if bucket doesn't exist), rate limits, or response format beyond a string. For a read operation with no annotation coverage, this is insufficient to fully inform agent behavior.

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 appropriately sized and front-loaded, with the core purpose stated first, followed by concise sections for arguments and returns. Every sentence adds value without redundancy, making it easy for an agent to parse quickly.

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 (1 parameter with nested objects, 0% schema coverage, no output schema, and no annotations), the description is incomplete. It explains the purpose and return type but does not address the input schema mismatch, behavioral aspects like error cases, or provide enough detail for reliable tool invocation. This leaves significant gaps for an agent to operate 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 has 0% description coverage and includes a nested object 'request' with no documented properties, while the description mentions 'bucket_name' as an optional parameter. This creates a contradiction: the description adds semantic meaning for a parameter not reflected in the schema, but fails to address the actual schema parameter 'request'. With low schema coverage and mismatched parameters, the description does not compensate effectively.

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 ('Get') and resource ('region where a bucket is located'), making the purpose specific and unambiguous. It distinguishes this tool from siblings like cloud_storage_list_buckets (which lists buckets) or cloud_storage_create_bucket (which creates buckets), as it focuses on retrieving location information for a specific bucket.

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 clear context for when to use this tool by specifying it retrieves bucket region information, implying it's for location queries rather than creation, deletion, or listing operations. However, it does not explicitly state when not to use it or name alternatives (e.g., cloud_storage_list_buckets for general bucket info), leaving some guidance gaps.

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