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: no indication of what "dedent" does to common leading whitespace, how tabs are handled, or whether input is mutated or returned.

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 brief, but the brevity reflects under-specification rather than efficiency: the single sentence is a redundant echo of the tool name and earns no informational value.

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 text-processing tool with two ambiguous parameters, no annotations, and no output schema, the description supplies essentially nothing an agent needs to select or invoke it 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?

Although schema coverage is 100%, the two parameters (text and input) have nearly identical, generic descriptions ("Text to process" / "Input to process"), and the description does nothing to clarify which is the intended payload or whether both are accepted. The baseline of 3 for full coverage is not warranted given the ambiguous duplication.

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?

"Dedent Lines: Dedent Lines" merely restates the tool name twice and offers no elaboration beyond the title. It conveys a vague sense of a text-transformation action on lines but does not disambiguate from siblings like x402-dedent, x402-indent-lines, or x402-trim-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 guidance about when to use this tool versus alternatives. With near-duplicate siblings such as x402-dedent and x402-indent-lines present, the absence of any routing guidance is a serious gap.

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