object_storage_create

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

No annotations exist, so the description carries the behavioral burden. It states the tool creates a resource and returns access credentials, but it does not disclose side effects, cost implications, permissions required, whether credentials are shown only once, or how this resource can be safely cleaned up.

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 short and well structured, with a purpose sentence followed by Args and Returns sections. No filler wording is present, although the Args/Returns formatting is mechanical rather than elegantly distilled.

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 two-parameter create call, the description provides enough to assemble the basics, but it lacks procedural guidance such as which sibling tool actually lists clusters and what happens to the returned credentials. With no annotations, missing behavioral and exclusion context keeps it from being complete.

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 compensates by explaining both parameters: cluster_id is the target cluster for the new instance, and label is a descriptive name. The pointer to a listing helper is useful, though the named tool is slightly inaccurate.

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 opens with a clear, specific action and resource: 'Create a new Object Storage instance.' The create verb and 'instance' distinguish it from object_storage_get/update/delete and other storage creation tools without ambiguity.

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 about when to choose this tool over alternatives. The only hint, 'use list_clusters to see options', is a parameter-level note and is left unattached to the actual sibling tool name object_storage_list_clusters. No when/when-not conditions are provided.

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