create_dns

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

With no annotations, the description must carry the safety and side-effect disclosure burden. It states the record-creation action and recommends dry-run, but doesn't explain whether existing records are replaced, whether special permissions/zone ownership are needed, how proxied/root/sensitive flags affect the write, or what response is returned. This is thin for a mutating DNS 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?

Two short sentences, front-loaded with the core operation and closing with a safety preference. There is no filler, and the single most important execution hint ('Prefer dry_run first') is included.

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?

For an 8-parameter mutating tool with no output schema and no annotations, this description is too sparse to be self-sufficient. It omits selection criteria versus upsert/update, effect of dry_run, handling of root/sensitive records, and return behavior, so the agent must infer or inspect the schema heavily.

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 63%, leaving ttl, allow_root, and allow_sensitive undocumented in the schema, and the tool description does not fill those gaps. It repeats the record types already in the type enum and adds only the word 'one,' which is minor value beyond the input schema.

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 opens with a concrete verb and object: 'Create one A, AAAA, CNAME, or TXT record.' This clearly identifies the operation and resource, and 'one' scopes it to a single record. It does not explicitly contrast with update_dns or upsert_dns, but the create verb is unambiguous enough for basic selection.

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?

The only usage guidance is 'Prefer dry_run first,' which tells the agent to plan before writing but not when to choose create_dns over update_dns or upsert_dns. The intended context (new record creation) is implied by the name and phrase, but no explicit when/when-not or alternative routing is given.

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