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

Annotations are absent, and the description provides no behavioral details: no side effects, no effect on input, no return shape, no ordering, and no edge-case behavior. It does not contradict any annotations, but it also carries none of the disclosure burden.

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 only six words, but they are duplicated in a 'Label: Value' pattern that adds no information. This is under-specification rather than disciplined conciseness.

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?

With no parameters, no annotations, and no output schema, the description needed to explain what text the tool operates on and what result is returned. It does neither, leaving the agent unable to know how to invoke this tool meaningfully.

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 tool has zero parameters, so there are no parameter semantics to document. The schema already fully captures the parameter surface, and the baseline of 4 applies.

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 is 'Remove Non Ascii: Remove Non Ascii' — a verbatim restatement of the tool's name. It is a tautology and provides no specification of what input is processed, what counts as non-ASCII, or how this differs from many sibling remove-* tools.

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 given for when to use this tool versus alternatives such as x402-remove-accents, x402-remove-control-chars, or x402-remove-whitespace. An agent is given no trigger condition, no context, and no exclusions.

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