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

With no annotations, the description carries full burden for behavioral disclosure. It states core operations (format, validate, minify) and the tree view, but does not explain behavior for invalid JSON, error handling, or the exact return format. This is a basic but not comprehensive disclosure.

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 of seven words, front-loading the key actions and the unique tree view. Every word earns its place, with zero redundancy or irrelevant detail.

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?

For a simple tool with well-documented parameters, the description covers main functionality, but lacks usage guidelines and behavioral details like validation error handling. The missing output schema increases the need for clarity, yet the description remains minimal, so it is only adequate.

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?

Schema coverage is 100% with descriptions for all parameters (json, indent, minify, sortKeys). The tool description adds no meaning beyond the schema, so baseline 3 applies. The description's verbs (format, minify) loosely map to parameters, but no extra insight is provided.

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 'Format, validate, minify JSON with tree view' uses specific verbs (format, validate, minify) tied to a specific resource (JSON) and mentions a distinctive tree view feature. This clearly distinguishes it from siblings like json-schema-validator, json-to-csv, and code-formatter, which have different scopes.

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 guidance is provided on when to use this tool versus alternatives, such as json-schema-validator for validation or code-formatter for general code formatting. There is no mention of prerequisites, use cases, or exclusions, so an AI agent receives no context for selection.

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