add_dns_static

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

The description only restates the action and does not disclose behavioral details such as what happens if the entry already exists, whether duplicate entries are created, or whether the change is persistent. The annotations indicate idempotentHint=false and destructiveHint=false, but the text adds no additional behavior beyond the name.

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 description is very concise, but its brevity crosses into under-specification. It repeats the title rather than front-loading useful semantic information; there is no structural helpful text such as expected combination of parameters.

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?

With six nullable parameters and no required fields, the description is incomplete. It doesn't explain what a valid target entry looks like, how TTL or comment behaves, or how address/cname/regexp are meant to be combined. Although an output schema exists, the input semantics are insufficiently described.

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?

The description provides no parameter semantics. Schema gives useful descriptions for name, cname, regexp, and address, but ttl and comment are unexplained, and the description doesn't clarify important constraints like how name, cname, regexp, and address interact or whether certain combinations are required/optional.

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 'Add a static DNS entry.' is essentially a restatement of the tool name (add_dns_static) and title ('Add Static DNS Entry'). It adds no conceptual distinction or details about what a static DNS entry entails or how it relates to siblings such as list_dns_static or remove_dns_static.

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 description gives no guidance about when to use this tool versus the many sibling tools (e.g., list_dns_static, remove_dns_static, make_lease_static). It provides no context for when this operation is appropriate, or when it should be avoided in favor of another tool.

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