format_json_visualizer

Visualize JSON data as an interactive tree with collapsible nodes, copy values, validate syntax, and lookup paths.

Instructions

Menu ID: json_visualizer. JSON Visualizer. Visualize JSON as an interactive tree with collapsible nodes, value copying, syntax validation, and path lookup. Explore deeply nested structures easily. Use describe_tool with tool_id "json_visualizer" for full page guidance.

Behavior2/5

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

No annotations provided, so the description carries full burden. It mentions features like syntax validation but does not clarify whether the tool is read-only, how the interactive tree is returned (e.g., HTML), or any side effects.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise at 50 words and front-loads the purpose. However, it repeats 'JSON Visualizer' after the menu ID, wasting space.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the lack of annotations and output schema, the description is incomplete. It omits details on output format, error handling for invalid JSON, and the nature of the interactive visualization in an MCP context.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 0% schema description coverage, the description should add meaning. It states 'Visualize JSON' but does not explain the required 'json' parameter format, constraints, or expected input syntax.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states 'Visualize JSON as an interactive tree with collapsible nodes, value copying, syntax validation, and path lookup.' This specifies a verb and resource, distinguishing it from the sibling tool 'format_json' which formats JSON without visualization.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description suggests using this tool to 'Explore deeply nested structures easily' and directs to describe_tool for full guidance. It implies when to use but lacks exclusions or comparisons to alternatives.

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