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

The description carries the full burden because no annotations are provided. It adds the 'Browser-based tool' hint, but does not disclose whether password-protected PDFs are supported, what happens to the original file, or what the output looks like. This is a notable gap for a tool that modifies files.

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 extremely concise, with one sentence giving the core action and a parenthetical adding context. No wasted words or redundant content.

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 is simple with zero parameters, but there is no output schema and no annotations, so the description should explain what the user gets (e.g., a downloaded unlocked PDF). It states what the tool does but omits return-value details and limitations, making it adequate but incomplete.

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 tool has zero parameters, so the input schema is trivially complete and the description does not need to explain parameter meaning. The baseline of 4 applies.

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 uses a specific verb ('Remove') and precisely states the target: edit/print/copy restrictions on PDFs. This clearly differentiates the tool from sibling PDF utilities like pdf-password or pdf-redact.

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 is given about when to use this tool versus alternatives such as pdf-password or pdf-edit, and no prerequisites or caveats are mentioned. The only extra context, 'Browser-based tool', does not help with tool selection.

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