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

With no annotations and no behavioral disclosure, the description fails to indicate whether this operation is read-only, destructive, or how it handles edge cases. It provides zero insight into the tool's actual behavior.

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 text is extremely short, but this is an under-specification problem rather than effective conciseness. There is no useful content or structure; it simply repeats the tool name.

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 has one undocumented parameter, no output schema, and no annotations, and the description provides no context about what 'paragraph split' means, what delimiters are used, or how results are returned. The definition is wholly inadequate.

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 coverage is 100% and the parameter is a generic 'Input to process', but the parameter name 'input' is uninformative; it does not clarify what kind of input is expected or what the tool will do with it. The description adds no semantic value beyond the schema's generic placeholder.

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 a tautology: 'Paragraph Split: Paragraph Split' simply restates the tool name without providing any actual information about what the tool does, how it processes input, or what output is expected. An agent cannot distinguish this from any other text-processing sibling.

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 on when to use this tool versus alternatives. The description gives no context about input formatting, expected text structure, or scenarios where paragraph splitting is appropriate.

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