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

No annotations provided, so the description carries full burden. It does not state what happens to the numbers (removed vs. kept), whether the input is mutated, what the output looks like, or any edge cases. The single word 'Strip' is insufficient for a mutation/text-processing 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?

Extremely short, but not front-loaded with useful information. It is concise but under-specified; every sentence (just one) does not earn its place because it repeats the name.

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?

The tool has two parameters, no output schema, and no annotations. The description is far too sparse to compensate. An agent would not know what to expect, especially with the ambiguous second parameter 'input' whose purpose is unclear.

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 100%, so the schema already documents both parameters ('text' and 'input'). The description adds nothing beyond the schema, but the baseline for high coverage with no param info in the description is 3.

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 'Strip Numbers: Strip Numbers.' restates the tool name without adding meaning. It does indicate the operation (strip numbers from text), which is marginally clearer than the name alone, but it is effectively a tautology.

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 on when to use this tool versus alternatives. Siblings like x402-extract-numbers or x402-strip-punctuation exist but are not referenced. The agent has no criteria for selection.

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