get_url_forwarding

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

No annotations are provided, so the description carries full burden. It implies a read operation but does not state side effects, permissions, rate limits, or error behavior. The description lacks transparency about what happens if the domain is invalid.

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 a single sentence, very concise. However, it is overly minimal and could be enriched with a bit more detail without losing conciseness (e.g., specifying it lists all rules). It does not waste words but also does not provide enough substance.

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?

Given no output schema, no annotations, and one poorly described parameter, the description is severely incomplete. It does not explain what the return data looks like, any pagination, or how to interpret results. The agent would have little guidance on how to use the tool effectively.

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%, and the description barely adds meaning. It mentions ``domain`` as a placeholder but does not explain what a valid domain format is or any constraints. The parameter's purpose is inferred from context but not explicitly clarified.

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 clearly states the verb 'List' and resource 'URL-forwarding rules' for a domain. It distinguishes from siblings like add_url_forward and delete_url_forward by indicating it's a listing operation. However, it could be more specific about listing 'all' rules.

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 on when to use this tool versus alternatives. The description does not mention prerequisites, typical use cases, or exclude scenarios (e.g., if domain doesn't exist).

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