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

No annotations are provided, so the description carries the full behavioral burden, and it discloses nothing: not whether the operation is idempotent, what normalization rules apply, what the return shape is, or how the three input parameters interact. This is a total gap for a mutation/transform tool.

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?

It is short, but the brevity comes from under-specification rather than economy — there is not a single informational sentence, and the colon-duplicated title wastes the only space available.

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 3-parameter transform tool with no annotations, no output schema, and no schema-level semantics, the description should at minimum state what is normalized, what the return value is, and how it differs from the other normalize tools. None of that is present.

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 description coverage is nominally 100%, but the three parameter descriptions are tautologies ("Form to process", "Text to process", "Input to process") that add no discriminating meaning, and the parameters themselves (form/text/input) are ambiguous and overlapping. The description adds nothing, and the schema text does not compensate.

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?

"Normalize: Normalize" restates the tool name twice and never names a resource or domain. With siblings x402-normalize-array, x402-normalize-vector and x402-normalize-whitespace in the same namespace, an agent has no basis for distinguishing this tool from those or from x402-standardize / x402-text-clean.

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 when-to-use guidance, no prerequisites, and no mention of the three near-identical siblings that compete for the same intent. The agent is left to guess from the name alone.

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