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

No annotations provided, so the description carries full behavioral burden, and it delivers nothing: no mutation semantics, no format expectations, no mention of whether it extracts links, converts links, or validates them. The description is silent on all behavioral traits.

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 short, but the brevity is under-specification rather than conciseness. Repeating the title twice wastes the only space available.

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 3-parameter tool with no annotations and no output schema, the description is completely inadequate. An agent has no basis to call 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?

Schema description coverage is 100%, which normally sets a baseline of 3, but the schema descriptions are themselves tautological ('Md to process', 'Text to process', 'Input to process'), so the structured data adds no meaning either. The description provides no parameter guidance to compensate.

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 'Markdown Links: Markdown Links', which merely restates the tool name/title. No verb, no resource scope, no distinction from the many markdown siblings such as x402-markdown, x402-markdown-html, or x402-markdown-toc. An agent cannot determine what this tool actually does with 'md', 'text', and 'input'.

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 when-to-use guidance, no alternatives, no exclusions. Given a swarm of markdown-related siblings, the absence of any routing information is fatal.

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