B3.3/5.0
Behavior3/5

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

Annotations indicate this is not read-only, idempotent, or destructive, but the description adds minimal behavioral context. It implies a generation process but doesn't detail effects (e.g., whether toolpaths are saved, visible in the UI, or trigger simulations). No contradiction with annotations exists, but the description could better explain the tool's impact beyond the basic hints.

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

Conciseness5/5

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

The description is a single, efficient sentence that front-loads the core purpose without unnecessary details. It uses clear language and avoids redundancy, making it easy to parse while conveying essential scope information.

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 lack of output schema and annotations that only cover basic hints, the description is somewhat incomplete. It doesn't explain what the tool returns (e.g., success status, generated paths) or address potential complexities like error handling for invalid inputs. However, it adequately covers the tool's intent within the context of CAM operations.

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?

Schema description coverage is 100%, so parameters are well-documented in the schema. The description mentions 'specific operation or all operations,' which aligns with the parameters but doesn't add significant semantic value beyond what the schema provides (e.g., clarifying interactions between 'setup_name', 'operation_name', and 'generate_all').

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 clearly states the action ('Generate toolpaths') and specifies the scope ('for a specific operation or all operations in a setup'), which distinguishes it from general CAM tools. However, it doesn't explicitly differentiate from sibling tools like 'cam_post_process' or 'cam_get_operation_info', which might involve related CAM workflows.

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?

The description provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., requiring an existing setup or operation), exclusions, or comparisons to siblings like 'cam_post_process' for post-processing or 'cam_list_operations' for listing operations without generation.

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