list_dns_records_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 usefully discloses pagination behavior, the per_page ceiling of 100, and the default page size, which is real operational context. However it says nothing about authentication requirements, rate limits, or whether results are eventually consistent, leaving gaps for a no-annotation tool.

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 Args/Returns layout is front-loaded with the one-line purpose followed by scannable parameter lines. It is appropriately sized for a six-parameter tool, with only minor redundancy between the filter parameters and the tool name.

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 spelled out, and the description correctly just notes the list-with-pagination shape. Combined with complete parameter documentation, the definition is nearly sufficient, with the missing usage guidance and auth context being the only notable residue.

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 is the only source of parameter meaning and it delivers for all six: zone_id as a 32-character hex string, type with concrete enum-like examples (A, AAAA, CNAME, MX, TXT), name and content filters, page default 1, and per_page max 100. It does not clarify filter combination or matching semantics (exact vs substring), which keeps it short of a 5.

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 DNS records for a Cloudflare zone.' This cleanly separates it from single-record siblings like get_dns_record_tool, but it never names those alternatives explicitly, so the differentiation is inferred 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 what this tool does versus get_dns_record_tool or list_zones_tool, and no preconditions such as required API token scopes. A user must infer from the filters that this is the broad enumeration call.

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