get_datastore_details

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

No annotations are provided, so the description bears full responsibility for disclosing behavior. It only states 'Get detailed information,' implying a read operation with no side effects, but fails to mention authentication, rate limits, or return format. This is insufficient for a tool with zero annotation support.

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 concise with two sentences, one for purpose and one listing parameters. It avoids excessive detail and is well-structured. However, it could be slightly more informative without sacrificing 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?

Although an output schema exists (not shown), the description lacks behavioral transparency, usage guidelines, and parameter semantics. It does not explain when to use this tool over list_datastores or other details tools, leaving gaps for an agent to make informed decisions.

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 0% schema description coverage, the description must compensate but only adds a minimal example for hostname ('e.g., vcenter.domain.local') and no additional context for datastore_id. The schema titles already convey basic meaning, so the description adds limited value beyond trivial examples.

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 'Get detailed information about a datastore,' which identifies the action and resource. It is specific to datastores and differentiates from sibling 'get_*_details' tools by resource type. However, it lacks detail on what 'detailed information' entails, leaving some 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?

The description provides no guidance on when to use this tool versus alternatives like list_datastores or other get_*_details tools. No contextual hints about prerequisites or conditions are given, leaving the agent to infer usage solely from the tool name.

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