cf_list_dns_records

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

With no annotations provided, the description carries the full burden of behavioral disclosure. 'Lists' implies a non-destructive read, but nothing is said about pagination behavior, filtering semantics, rate limits, or what the response contains. For a tool with page/perPage parameters, the absence of any pagination note is a notable gap.

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?

One efficient sentence with no wasted words, but it largely restates the tool name (cf_list_dns_records → 'Lists DNS records'). This is under-specification rather than deliberate brevity; there was room to add filtering or pagination context without bloating the description.

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 5 parameters, no output schema, and no annotations, a single sentence is inadequate. Missing guidance on how zoneId is obtained, what type/name filters do, and pagination behavior leaves the agent to experiment or read the schema. The definition is not catastrophic (the resource is clear), but it is far from complete for a tool with this parameter count.

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 20%, so the description should compensate, but it mentions no parameters at all. Only zoneId has an inline description in the schema; name, page, type, and perPage are left to inference. The description adds zero value beyond what the parameter names already convey.

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 ('Lists') and resource ('DNS records for a Cloudflare zone'), clearly identifying a read operation scoped to Cloudflare. It is distinguishable from cf_create_dns_record (write) and cf_get_analytics by resource, though it doesn't explicitly contrast with monitor_dns_lookup.

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. It doesn't mention that cf_get_zones would be needed to obtain the zoneId, nor how it differs from monitor_dns_lookup or monitor_dns_propagation for DNS inspection. The agent must infer the use case entirely from the tool name.

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