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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds nothing beyond that - it never says what is validated, whether a report or boolean is returned, or what 'client and server side' implies for execution.

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 single sentence is short, but it is short because it is under-specified, and it spends words on vendor branding ('client and server side from freedailypro') rather than the front-loaded purpose an agent needs.

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?

A one-parameter read-only tool is simple, and there is no output schema, so the description must explain the input format and the nature of the result - neither is present. The definition does not give enough for an agent to call it confidently.

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 0% for the single required 'text' parameter, and the description does not compensate at all - it never indicates whether the input is plain paper text, LaTeX, or a citation string. The agent must guess the expected input format.

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 phrase 'paper format checker' gestures at a verb (check) and a resource (paper format), but 'paper format' is never defined - it could mean academic citation layout, stationery size, or print margins. The trailing 'client and server side from freedailypro' is vendor attribution rather than clarification of what the tool actually does.

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 statement of when to use this tool, no comparison to any sibling (e.g. check_grammar, word_count, or the publishing_* tools), and no prerequisites or exclusions. The agent must infer usage entirely from the name.

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