list_url_rewrite_rules_tool

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

No annotations are provided, so the description carries the full burden. It discloses only the return shape ('Ruleset with URL rewrite rules') and implies a safe read via 'List'; it says nothing about permissions, pagination, or whether an empty result is possible.

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?

Front-loaded with the action, followed by tight Args/Returns sections and no filler. It is appropriately sized for a one-parameter read tool.

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?

An output schema exists, so the description need not detail return values, and it correctly avoids doing so. What is missing is behavior the schema cannot express: auth requirements, pagination, and the relationship to the set/update siblings.

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 must compensate, and it does add real value by specifying zone_id as a '32-character hex string'. However, that is the entirety of the parameter documentation, leaving format errors and constraints to be discovered by trial.

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?

States a specific verb+resource ('List URL rewrite rules'), which clearly separates it from the sibling set_url_rewrite_rules_tool. It stops short of explicitly naming that sibling or the resource scope (zone-level), so sibling differentiation is implied rather than stated.

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 when-to-use guidance, no mention of the alternative set_url_rewrite_rules_tool for modifying rules, and no prerequisites. A reader can infer from the name that this is the read counterpart, but the description supplies nothing explicit.

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