update_bind_settings

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

Annotations declare readOnlyHint=false, idempotentHint=true, and destructiveHint=false, which already convey the core safety profile. The description adds no behavioral context beyond 'Update,' such as potential service disruption, the role of apply_immediately, or whether changes are staged. It does not contradict annotations, but it provides no additional transparency.

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 a single sentence that is direct and front-loaded with the verb and resource. It contains no filler or redundant information, making it highly concise and efficient.

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 the presence of an output schema and complete parameter descriptions, the tool is functionally usable from structured data alone. However, the description lacks high-level context about effects, such as whether changes require a service restart or how apply_immediately impacts behavior, making it adequate but not fully comprehensive for a 7-parameter settings update tool.

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 provides descriptions for all 7 parameters (enable, listen_on, rate_limit, log_severity, forwarder_ips, apply_immediately, dnssec_validation), achieving 100% schema description coverage. The description adds no extra parameter semantics, so the baseline score of 3 is appropriate.

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 states 'Update BIND DNS server settings,' which clearly specifies the verb (update), resource (BIND DNS server), and scope (settings). This distinguishes it from zone-specific operations such as update_bind_zone, and from other DNS update tools like update_dns_resolver_settings or update_dns_forwarder_settings.

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 guidance on when to use this tool versus alternatives. It does not mention that get_bind_settings should be used for reading current settings or that update_bind_zone is for zone configuration. The description simply states the action without contextual prerequisites or exclusions.

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