Get storage bucket

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the description is consistent but adds minimal behavioral context. It provides no additional details about authentication, rate limits, or what 'details' are returned. The scope ('one') is more about purpose than behavior, so the description meets the baseline without adding extra disclosure.

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 concise sentence with no redundant information. It is front-loaded with the action and resource, and every word contributes to understanding the tool's purpose.

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?

The tool is simple (one parameter, read-only, no output schema), and the description sufficiently explains what it does for an agent to select it. It could be slightly more complete by specifying what 'details' include or when to use it over siblings like get_bucket_metrics, but the current level is adequate for a straightforward get operation.

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% with the bucket_id parameter described as 'Bucket ID'. The description does not add additional parameter semantics beyond the schema, but it aligns with the parameter by implying the bucket is identified by ID. This matches 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 states a specific action ('Get'), a specific resource ('cloud storage bucket'), and a scope ('one'), which clearly distinguishes it from list_buckets and other sibling tools. This is a precise verb+resource+scope construction.

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?

There is no guidance on when to use this tool versus alternatives. It does not mention that it is for retrieving a single bucket by ID, while list_buckets is for enumerating multiple buckets, nor does it reference any other related tools.

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