load_diagram

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only states the action 'load from file' without explaining side effects (e.g., replacing the current diagram), error handling, supported file formats, or permissions. This is inadequate for safe and correct usage.

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 concise sentence in Chinese, '从文件加载图表', with the verb and object front-loaded. It contains no unnecessary words or repetition, earning its place entirely.

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?

Given the tool has one parameter, no output schema, and no annotations, the description is too thin. It omits critical context such as return behavior, whether loading replaces the current diagram, supported file types, and potential errors. This leaves the agent with incomplete information for a task that could have side effects.

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 provides 100% coverage with the parameter 'filename' described as '文件名' (filename). The tool description adds no extra semantics beyond what the schema already states, and since schema coverage is high, the baseline of 3 is appropriate.

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 states '从文件加载图表' (Load diagram from file), specifying the verb 'load' and the resource 'diagram', which clearly distinguishes it from sibling tools like save_diagram and create_diagram. It is a concise and unambiguous statement of the operation.

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 description provides no guidance on when to use this tool versus alternatives such as save_diagram, export_diagram, or create_diagram. There is no mention of preferred scenarios, prerequisites, or exclusions, leaving the agent without selection criteria.

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