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

With no annotations provided, the description carries the full burden of behavioral disclosure and discloses nothing. It doesn't say whether the operation is a pure transformation, where input comes from given the empty schema, what the return value looks like, or which lines are affected.

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?

Four words, but they are pure repetition: a 'Dedent Lines:' header plus the same phrase again. This is under-specification, not economy — there is no informative content to be concise about, and the redundant title prefix adds noise.

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 zero-parameter, no-annotation, no-output-schema tool, the description must at minimum state what text it operates on and what it returns; it states neither. An agent cannot know why x402-dedent-lines differs from x402-dedent or x402-indent-lines, so it is not minimally viable.

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 schema has zero properties, so schema coverage is vacuously 100% and the 0-param baseline applies. However, a dedenting operation normally requires text input, and the description never explains how the tool receives it — leaving the empty parameter surface genuinely ambiguous rather than trivially complete.

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 literally 'Dedent Lines: Dedent Lines' — a verbatim restatement of the tool name. It explains neither what dedenting does, what text it operates on, nor what result it produces. With dozens of text-manipulation siblings (x402-dedent, x402-indent-lines, x402-trim-lines, x402-text-indent), it offers zero differentiation.

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 sentence about when to invoke this tool or when to prefer a sibling. No conditions, no exclusions, and no alternatives are mentioned — an agent receives no guidance for selecting this tool over x402-dedent or x402-indent-lines.

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