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, yet it discloses nothing: not whether the operation is case-sensitive, whether it preserves order, what it does with adjacent vs. non-adjacent repeats, or what the return shape is.

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 consists solely of a duplicated name-title fragment with no informational payload. This is under-specification rather than conciseness — no sentence earns its place.

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 text utility this could be minimal, but with no annotations, no output schema, and two indistinguishable input parameters, the description leaves the agent without enough to invoke the tool correctly or predict its behavior.

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 nominally 100%, but both parameters are near-synonymous strings ('text' = 'Text to process', 'input' = 'Input to process'), creating real ambiguity the description makes no attempt to resolve. It adds zero meaning beyond the schema, so it falls below the baseline-3 case for well-covered schemas.

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 text 'Remove Duplicates Words: Remove Duplicates Words' is a tautology that merely restates the tool name/title with no added specificity. It doesn't clarify whether duplicates are removed per-line, case-sensitively, or globally, nor does it distinguish it from near siblings like x402-remove-duplicates or x402-duplicate-lines.

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 mention of alternatives, and no conditions under which this tool should be chosen over the many overlapping text-dedup siblings. Nothing in the description routes the agent.

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