open_model_file

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

Annotations already declare destructiveHint=true, so the agent is warned that opening may alter or replace current state. The description itself adds no further behavioral context, such as whether the current model is replaced or unsaved changes are lost, but it does not contradict the annotations.

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 text is compact and front-loaded: one sentence states the core action, and one line documents the single parameter. The bilingual phrasing adds clarity without meaningful 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?

The essential input is documented, but the description does not explain the resulting state change, such as the opened model becoming the active model for subsequent API calls, nor the destructive consequence implied by the annotation. With no output schema, this lightly reduces completeness.

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 input schema only says 'File Path' with no description, so the description's 'Absolute or relative path to the .qtb file' carries the entire semantic burden and fully specifies how file_path should be provided. This fully compensates for the 0% schema description coverage.

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 uses a specific verb ('Open') and resource ('existing model file') and identifies the .qtb format, clearly distinguishing this loading operation from siblings like initialize_model or save_model_file. The action and target are unambiguous.

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 'existing' implies this tool should be used for loading a previously saved .qtb model, but the description does not explicitly state when to use it over initialize_model or save_model_file, nor does it mention prerequisites or exclusions. Usage context is only implied, not stated.

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