get_item

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

No annotations are provided, so the description carries the full burden for behavioral disclosure. The verb 'Get' implies a read-only operation, but the description says nothing about side effects, not-found behavior, permissions, or return format, leaving the agent with only the tool name as a clue.

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, front-loaded sentence with no filler or redundant information. For a simple get-by-ID operation, this level of conciseness is appropriate.

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?

The tool is simple with one required parameter and no output schema, so the description is almost usable on its own. However, it never defines what an 'item' is in this accounting domain, and the lack of an output schema leaves the agent without any expectation of the response shape.

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 schema has 0% description coverage, but the single parameter is named 'id' with an integer type and exclusiveMinimum 0, which is largely self-explanatory. The description reinforces that the ID identifies the item, though it adds no additional format or domain detail.

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 names a specific verb ('Get'), a resource ('item'), and a lookup key ('by ID'), which makes the tool's core action clear. It distinguishes this from sibling write and list tools like create_item and list_items, though it does not elaborate on what an 'item' is in this domain.

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?

There is no explicit guidance on when to use this tool versus alternatives like list_items, create_item, or update_item. The phrase 'by ID' implies a single-record lookup, but the description never states the condition, exclusions, or recommended alternative.

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