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

With no annotations, the description carries the full burden of behavioral disclosure, and it reveals nothing: no input requirements, no side effects, no return shape, no edge-case behavior. For a 0-parameter tool with no output schema, an agent receives zero behavioral signal beyond what the tool name itself implies.

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 short, but this is under-specification, not conciseness. It front-loads a redundant label ('Min Max Normalize') and then supplies a garbled fragment; no sentence earns its place because neither sentence communicates usable information.

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?

This is a data-transform tool with no annotations, no output schema, no parameters, and a two-phrase description. Missing entirely are the input mechanism, the output format, the normalization formula, and degenerate cases like all-equal inputs causing division by zero. The definition is far below the minimum needed for an agent to invoke the tool correctly.

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 schema has zero properties, so it documents no parameters, and the description does not compensate by explaining how the data to be normalized is supplied. A min-max normalization operation inherently needs a dataset or value to transform, yet nothing tells the agent how to provide it, leaving the tool effectively uncallable.

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 'Min Max Normalize: Minimum of max normalize' is a tautological restatement of the tool name followed by an ungrammatical fragment that conveys no verb, no operation, and no resource. It fails to state that this performs min-max scaling of data to a range, and it does nothing to distinguish the tool from siblings like x402-normalize, x402-standardize-array, or x402-clamp.

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?

There is no guidance about when to use this tool versus any of its many normalization/standardization siblings (e.g., x402-normalize, x402-normalize-array, x402-standardize, x402-feed-normalize). No context, conditions, or exclusions are provided, so the agent must guess which tool is appropriate.

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