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

No annotations are provided, so the description must carry the full behavioral burden. It discloses important operational context like paid auth mode, price, and endpoint, but it does not state side effects, return format, or whether the operation is purely read-only. The cost/auth disclosure is useful, but core behavioral transparency remains limited.

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 heavily bloated with origin URL, hostname, brand, aliases, family key, keywords, repeated summary text, and pricing metadata. The useful tool summary is buried after machine-generated fields and repeated in 'Source description.' It is not front-loaded or concise.

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 four-parameter text-transform tool with no annotations, no output schema, and 0% schema description coverage, the description is incomplete. It gives a functional summary and use cases but omits parameter semantics, defaults, and return-value expectations. An agent would need schema inference 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 0%, so the description needs to compensate, but it only vaguely references an optional length limit and accent stripping behavior. It does not explain the required 'text' parameter, or the 'lowercase' and 'separator' parameters and their defaults. The schema is left largely undocumented.

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 summary states a specific verb and resource: 'Convert a title into a clean URL slug with accent stripping and optional length limit.' The purpose is clear and distinct from text-normalization or detection siblings. It does not explicitly differentiate against sibling tools, but the operation itself is unambiguous.

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?

Three 'Use case' lines provide clear contexts for when to use the tool, such as turning Persian or accented titles into URL slugs and generating permalinks. There are no exclusions or sibling alternatives, but the intended usage context is explicit enough for an agent.

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