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

No annotations are provided, so the description must disclose behavior on its own. It states the basic operation but omits all transformation behavior (lowercasing, accent stripping, separator choice, repeat collapsing, length limiting) and any error or idempotency behavior, which is a significant gap for a six-parameter utility.

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 front-loaded, grammatical, and free of waste. However, it is under-specified for a tool with six parameters and no annotations, so it is concise without being appropriately sized for the task.

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?

With no annotations, no output schema, 17% schema description coverage, and six parameters, the description should carry substantial explanatory weight. Instead it offers only one sentence and leaves parameter behavior and transformation rules completely undocumented.

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 only 17%, and the description does not mention any of the six parameters. Options like lowercase, separator, maxLength, stripAccents, and collapseRepeats are left entirely to schema names and defaults, so the description adds no meaning beyond the structured fields.

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 names a specific verb ('Generate') and resource ('URL slug') and states the input source ('from a string'). It clearly distinguishes the tool's purpose from siblings like url_encode or uuid_generate, though it does not explicitly compare itself to them.

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?

The description gives no explicit when-to-use guidance, no exclusions, and no alternatives. It does not tell an agent when to choose slug_generate over url_encode or other text utilities.

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