get_inventory

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

No annotations are provided, so the description carries the full burden. It implies this is a read-only operation (inventory) but doesn't explicitly state behavioral traits like whether it requires authentication, has rate limits, or returns structured data. The description adds some context about what hardware components are included, but lacks details on output format or potential constraints.

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 highly concise and front-loaded, consisting of just two sentences that efficiently convey the tool's scope and usage without any wasted words. Every sentence adds clear value.

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 the tool has no parameters and no output schema, the description provides adequate context for a simple inventory tool, but lacks details on what the return value looks like (e.g., format, structure) and doesn't mention any behavioral constraints. It's complete enough for basic use but has gaps in transparency.

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 tool has 0 parameters, and schema description coverage is 100%. With no parameters to document, the description appropriately doesn't discuss parameters, and the baseline for this scenario is 4 as it doesn't need to compensate for any gaps.

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 specific verbs ('Complete hardware inventory') and resources ('CPUs, DIMMs, PCI cards, network adapters, and storage controllers'), and explicitly distinguishes it from siblings by answering 'What hardware is in this server?' which differentiates it from more specialized tools like get_network_adapters or get_storage_summary.

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 explicit guidance on when to use this tool ('Answers "What hardware is in this server?"'), which clearly indicates it should be used for comprehensive hardware queries rather than the more specific sibling tools that focus on subsets like network adapters or storage.

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