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

With no annotations, the description carries the burden of behavioral disclosure. It implies a read-only analysis operation through 'Analyze' and 'recommendations', and adds the useful behavioral trait that labels can be used in addition to IDs. However, it does not explicitly confirm that no modifications are made or mention any side effects.

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 compact and front-loaded, with clear Args and Returns sections. Minor redundancy exists between the opening sentence and the Returns line, but no filler or unnecessary detail is present.

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 single-parameter analysis tool with an output schema, the description covers the essential invocation information. It lacks explicit guidance on prerequisites or error scenarios, but given the low complexity and the presence of an output schema, the description is adequately 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%, so the description must compensate. It does so by explaining that `gateway_identifier` accepts a label or an ID, adding meaningful semantic detail beyond the bare string type in the input schema.

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 a specific action ('Analyze and provide optimization recommendations') on a specific resource ('storage gateway'). The purpose is distinct from sibling tools like storage_gateway_get_gateway_status or storage_gateway_get_cost_analysis, though it does not explicitly name those alternatives.

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?

No guidance is given for when to use this tool versus other storage_gateway analysis or management tools. The only usage-related note is about identifier resolution ('Use gateway label or ID'), which is a parameter detail rather than contextual selection guidance.

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