B3.2/5.0
Behavior3/5

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

With no annotations provided, the description carries the full burden of behavioral disclosure. The verb 'List' implies a read-only operation scrap no explicit statement that the simulation is not modified, and no mention of what is returned or how errors are handled. This is minimally sufficient for a simple listing tool but lacks richer behavioral context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is front-loaded with the purpose and includes a compact Args section with no redundant prose. It earns its place, though the formatting includes a blank line and the parameter documentation could be embedded more tightly. Still, it is appropriately sized for a one-parameter read-only tool.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has one required parameter directly documented-labore no output schema or annotations, the definition is callable but incomplete. It does not state what the returned value looks like, whether it returns object names, paths, or handles, or how this tool relates to get_dop_object and get_dop_field. An agent would likely need additional context to confidently use the result.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema provides no description for node_path, and schema description coverage is 0%, so the description must compensate. The line 'node_path: DOP network node path' adds the key clarification that the parameter refers to a DOP network node path, which is useful beyond the schema title 'Node Path.' However, it does not provide examples, path format expectations, or what node types are valid.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific action and resource: 'List all DOP objects in a simulation.' This clearly identifies the operation's scope and differentiates it from sibling tools like get_dop_object, which suggests fetching a single object. It stops short of a 5 because it does not explicitly contrast itself with related DOP tools like get_dop_relationships or get_dop_field.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance on when to use this tool versus alternatives. The description does not mention sibling tools such as get_dop_object, get_dop_relationships, or get_simulation_info, nor does it state what kind of node_path is required or what scenario warrants listing all DOP objects. An agent must infer usage from the tool name alone.

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