webdev_json_schema_generator

Generate JSON Schema definitions from JSON data to validate and document your JSON structures.

Instructions

Menu ID: json_schema_gen. JSON Schema Generator. Generate JSON Schema definitions from JSON data for validation and documentation. Use describe_tool with tool_id "json_schema_gen" for full page guidance.

Behavior2/5

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

With no annotations, the description carries full burden for behavioral traits. It omits key details such as input structure, output format, idempotence, or authentication needs. The phrase 'Generate' implies mutation but lacks clarity on side effects or prerequisites.

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 short but includes an internal 'Menu ID' which is not directly useful. The core purpose is stated after the ID, which is acceptable but not optimally front-loaded. Every sentence serves some purpose, but there is some redundancy with the title.

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 no output schema and no parameter definitions, the description should explain return values and input expectations. It does neither. The suggestion to use describe_tool indicates incompleteness. For a tool with no structured schema richness, the description is insufficient.

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?

The input schema has no defined properties (only additionalProperties: true), so the agent does not know what to pass. The description mentions 'from JSON data' but provides no structure or required fields. With 0 defined parameters, baseline is 4, but the description fails to compensate for the empty schema.

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

Purpose4/5

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

The description clearly states the tool's purpose: 'Generate JSON Schema definitions from JSON data for validation and documentation.' This is a specific verb+resource. However, it does not distinguish from the sibling tool 'data_json_schema_validator' which validates against a schema, so a perfect score is not warranted.

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

Usage Guidelines2/5

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 vs alternatives. It only suggests using describe_tool for full guidance, but does not give any context about when this tool is appropriate. No when-not or alternative mentions.

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