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

With no annotations provided, the description carries the full burden. It indicates this is a read operation ('Get') and describes what information will be returned (health, exports, network configuration). However, it doesn't disclose important behavioral aspects like authentication requirements, rate limits, error conditions, or whether this operation has 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 perfectly structured and front-loaded. The first sentence states the core purpose, followed by specific guidance about identifier resolution, then clearly separated sections for Args and Returns. Every sentence earns its place with no wasted words.

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 read tool with no annotations and no output schema, the description provides adequate basic information about purpose and parameters. However, it could be more complete by mentioning authentication requirements, error handling, or providing examples of the returned status structure beyond the high-level categories listed.

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?

The description adds significant value beyond the schema. With 0% schema description coverage for the single parameter, the description explains that 'gateway_identifier' accepts either a 'gateway label or ID' and mentions 'Smart identifier resolution.' This provides crucial semantic context that the bare schema lacks.

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 the tool's purpose with a specific verb ('Get') and resource ('comprehensive status information for a storage gateway'). It distinguishes itself from siblings like 'get_health_status' or 'get_status_overview' by specifying it's for storage gateways and includes exports and network configuration details.

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 clear context for when to use this tool ('for a storage gateway') and mentions smart identifier resolution (label or ID). However, it doesn't explicitly state when NOT to use it or name specific alternatives among the many sibling tools, though the specificity implies it's for storage gateways only.

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