list_page_rules_tool

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

With no annotations, the description carries the full behavioral burden, and it does relatively little: it implies a read via 'List' but never states read-only safety, required permissions, pagination/limit behavior, or rate limits. For a list endpoint in a large API surface with zero annotation coverage, those omissions are material.

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 purpose followed by compact Args/Returns blocks with no filler. The structure is scannable and appropriately sized for a three-parameter list 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 return values need not be described, and parameters are covered. What is missing is behavioral context an agent would want: pagination behavior for a potentially large list, ordering defaults, and any read-safety signal absent from annotations.

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: it names each of the three parameters and supplies the enum-ish values the schema lacks (status: active/disabled; order: status/priority) plus the zone_id format (32-character hex string). The only gap is not stating which parameter is required or the default sort behavior.

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 and resource: 'List all page rules for a zone.' The resource is distinct from siblings like list_response_header_rules_tool and list_url_rewrite_rules_tool, so an agent can identify it as the page-rules lister. However, it never explicitly contrasts itself with those sibling list tools, so it lands at 4 rather than 5.

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 prerequisites, and no mention of alternatives among the many sibling list tools (response header rules, request header rules, URL rewrite rules). Usage is only implied by the verb 'List.'

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