Load staged file into Cura

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

Annotations already declare readOnlyHint=false and destructiveHint=true, so the mutating nature is known; the description usefully adds that it will not slice or trigger a print. It does not, however, explain what 'loading' changes in the workspace or why the operation is destructive, nor anything about the confirmation-token requirement beyond the adjective 'confirmed'.

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?

Two tight sentences with the core action front-loaded and the boundary immediately after. Every clause earns its place with no filler or redundancy.

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 destructive, write-mode tool with no output schema and zero param documentation, the description covers purpose and scope but omits the confirmation flow that the required confirmation_token implies and the effect of project_mode. An agent could call it, but key mechanics remain unclear.

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% for three parameters, and the description compensates for none of them. It never explains file_path, the purpose of confirmation_token, or how project_mode's open_as_project/open_as_model enum changes behavior, so an agent must infer parameter meaning entirely from names and types.

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?

States a specific verb (loads) and resource (a confirmed staged model/project/G-code/UFP file) with a clear target (the active Cura workspace). The boundary sentence 'It does not slice or send a print' implicitly separates it from siblings like start_print and preflight_print_action, though it never names an alternative directly.

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?

The word 'confirmed staged' implies a prerequisite flow (create_cura_confirmation/confirm_cura_operation) and the 'does not slice or send a print' clause gives an implicit when-not boundary. But it never explicitly states when to choose this tool over cura_operation, start_print, or upload_gcode, leaving the routing to inference.

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