Get Object Storage bucket metrics

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

Annotations already declare readOnlyHint=true and openWorldHint=true, and the '[READ]' tag merely repeats that. The description adds only the API base URL and version, which is mildly useful for endpoint context but says nothing about what metrics are returned, time ranges, authentication, or rate limits. No contradiction with annotations.

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?

A single compact line with no filler, and the read/endpoint information is front-loaded. However, brevity here reflects under-specification rather than disciplined conciseness.

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?

With no output schema and 0% parameter coverage, the description should explain what metrics are returned and what the bucket parameter expects; it does neither. For a metrics retrieval endpoint, the return-value semantics are the single most important thing an agent needs, and they are absent.

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%, so the schema only says 'bucket' is a non-empty string. The URL template '{bucketName}' is the sole hint that the parameter is a bucket name, with no format, example, or namespace/account qualification. This barely compensates for the coverage gap.

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 is essentially a restatement of the tool name in URL form ('GET .../buckets/{bucketName}/metrics'), with no statement of what the metrics actually are or what they measure. It identifies the resource and verb only implicitly through the endpoint path, and does nothing to distinguish it from siblings like get_storage_report or list_storage_api_buckets.

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 when-to-use guidance, no prerequisites, and no mention of alternatives such as get_storage_report. The endpoint reference implies this returns metrics for one bucket, but nothing tells the agent when this is the right tool versus other storage reporting tools.

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