validate_mermaid_syntax

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. It mentions '尝试简单转换' (attempting simple conversion) as the validation method, which implies a read-only, non-destructive operation, but doesn't clarify error handling, performance implications, or what '简单转换' entails. For a tool with zero annotation coverage, this leaves significant gaps in understanding its behavior.

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 extremely concise and well-structured: a purpose statement followed by clear parameter and return sections in bullet-like format. Every sentence earns its place without redundancy, and it's front-loaded with the core functionality. The bilingual presentation (Chinese purpose, English labels) is efficient for clarity.

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's low complexity (single parameter, no nested objects) and the presence of an output schema (which handles return values), the description is reasonably complete. It covers purpose, parameter semantics, and return type at a high level. However, it lacks usage guidelines and detailed behavioral context, which are minor gaps in this simple validation context.

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 description explicitly documents the single parameter 'mermaid_code' as '要验证的 Mermaid 图表语法代码' (Mermaid diagram syntax code to validate), adding meaning beyond the schema's basic title 'Mermaid Code'. However, with schema description coverage at 0%, it doesn't provide format details, constraints, or examples. The baseline is 3 since it compensates somewhat but not fully for the schema's lack of descriptions.

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 clearly states the tool's purpose as '验证 Mermaid 图表语法' (validate Mermaid diagram syntax) and specifies the method '通过尝试简单转换' (by attempting simple conversion). It distinguishes from sibling tools like 'convert_mermaid_to_image' by focusing on validation rather than conversion to image format. However, it doesn't explicitly differentiate from 'get_supported_options' which might relate to syntax options.

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. It doesn't mention sibling tools 'convert_mermaid_to_image' or 'get_supported_options', nor does it specify scenarios where validation is preferred over direct conversion or option checking. There's no indication of prerequisites or exclusions for usage.

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