inventory_get

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

With no annotations provided, the description carries the burden of conveying behavior. 'Look up' clearly signals a read-only lookup with no mutation, and the scope is limited to the hops inventory. It doesn't discuss error cases or missing IDs, but for a simple getter this is reasonably transparent.

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 extremely compact and front-loaded: one clear action sentence followed by a single parameter note. Every sentence contributes necessary information with no filler.

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 one-parameter getter with an output schema, the description is complete. It states what is retrieved, the target inventory, and how to source the parameter. No additional behavioral context is essential for correct invocation.

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 adds meaningful provenance: 'id from inventory_list' tells the agent exactly how to obtain a valid server_id, going beyond the schema's bare 'Server Id' title.

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 and resource: 'Look up one server in the hops inventory.' It clearly identifies the tool as a singular getter, distinguishing it from inventory_list and inventory_this.

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?

It provides clear context by stating the server_id comes from inventory_list, implying the tool should be used when you already have an ID from that list. It doesn't explicitly name alternatives or exclusions, but the intended usage is obvious.

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