create_inventory

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

With no annotations provided, the description carries the burden of behavioral disclosure. It accurately indicates a create operation with optional device population and adds context about inventory purpose. However, it does not disclose requirements like valid authorization groups, permissions, or potential side effects beyond creation.

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 front-loaded with the core action in the first sentence. The second sentence provides useful context for why inventories matter, and the third clarifies timing of device population. It is concise without excessive fluff, though the second sentence is slightly promotional.

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?

Given a complete input schema and an output schema, the description adequately explains the tool's purpose and options. It lacks explicit prerequisites (e.g., authorization groups must already exist), but the required 'groups' parameter is visible in the schema, making the description sufficient for a create operation.

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 input schema covers all four parameters with full descriptions, so the description adds little beyond what the schema already provides. The only added meaning is reiterating that devices may be populated 'during creation or later', which is already implied by the schema's devices field.

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 uses a specific verb 'Create' with a clear resource ('inventory') and notes optional device population, making the tool's purpose unambiguous. It also distinguishes from related sibling tools like add_nodes_to_inventory by clarifying that devices can be added later, and from create_device_group/create_template by explicitly naming 'inventory'.

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 explains the context of inventories ('logical organization of network devices') and states that devices can be added during creation or later, implicitly pointing to add_nodes_to_inventory for later additions. However, it does not explicitly name alternative tools or state when it should not be used, stopping short of full guideline clarity.

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