visualize_schema

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

The description says 'Prompt for visualizing', which suggests it generates a prompt rather than executing directly, but this is not elaborated. With no annotations provided, the description should disclose more behavioral traits such as mutability, permissions, or output format beyond the output schema.

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 that front-loads the key action and tool output. Every word earns its place without 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?

Given the tool simplicity (zero params, output schema present), the description is minimally adequate. However, it could mention that it generates a Mermaid class diagram and that it is a prompt (not direct execution), to reduce ambiguity with sibling tools.

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?

There are no parameters, and the schema coverage is 100%, so baseline is 4. The description adds no parameter information, but none is needed since all parameters are already captured in the input schema.

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 action ('visualizing'), the resource ('knowledge graph schema'), and the method ('Mermaid class diagram'). It distinguishes from sibling tool 'get_neo4j_schema' which retrieves raw schema data, while this tool produces a visual diagram.

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?

No explicit guidance on when to use this tool versus alternatives like 'get_neo4j_schema' or 'clean_mermaid_diagram'. The usage is implied but not stated, leaving room for confusion.

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