dns_set_zone_options

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

No annotations are provided, so the description must disclose behavioral traits. It states 'update' implying mutation and 'key/value pairs' suggesting partial updates. However, it does not specify behavior on missing parameters, idempotency, zone existence requirements, or return value, leaving moderate gaps.

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 two sentences with no superfluous words. It front-loads the purpose and adds a brief usage hint. Every sentence contributes meaning.

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 a mutation tool with 4 parameters and no output schema, the description covers the action and usage pattern but omits output details (e.g., what is returned) and any validation behavior. It is adequate but not fully comprehensive.

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 input schema has 100% description coverage, so the bar is baseline 3. The description adds 'plus any option key/value pairs' and examples, reinforcing the schema meaning but not providing new semantic value beyond what the parameter descriptions 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?

The description clearly states the verb 'Set' and resource 'configuration options for a zone'. It gives concrete examples (notify settings, zone transfer ACLs) which distinguishes it from sibling tools like dns_create_zone or dns_zone_options, making the purpose unambiguous.

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 implies usage context: to modify existing zone settings. It does not explicitly contrast with alternatives (e.g., dns_zone_options for reading, dns_set_settings for server settings), but the phrase 'Set configuration options for a zone' combined with sibling names provides sufficient guidance. Missing explicit 'when not to use' prevents a 5.

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