get_item_summary

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

No annotations exist. The description lists the fields returned but does not disclose any behavioral traits such as read-only nature, authentication requirements, or side effects. The lack of output schema exacerbates this gap.

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 a single sentence, front-loaded with key info, but it omits critical details about the parameter and return format. Its brevity sacrifices completeness.

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 simplicity of the tool (1 param, no nested objects), the description should at least clarify the parameter's nature and the return structure beyond listing fields. It fails to provide enough context for an agent to confidently select and invoke it.

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 single parameter 'name_or_id' has 0% schema description coverage, and the tool description does not provide any details on its meaning or expected format (e.g., numeric ID vs string name). The agent cannot infer how to populate it correctly.

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 retrieves a concise summary of an item with specific fields (name, category, cost, effect description). It implicitly distinguishes from sibling 'get_item' which likely returns full details, but does not explicitly differentiate.

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 provided on when to use this tool vs alternatives like 'get_item' or 'list_items'. The description does not mention use cases or exclusions.

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