update_bind_zone

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

Annotations already declare readOnlyHint=false, idempotentHint=true, and destructiveHint=false, establishing the safety profile. The description adds no behavioral context beyond the action itself, such as whether changes require separate application (despite the apply_immediately parameter) or how partial updates are handled.

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 succinct sentence—'Update an existing BIND DNS zone by ID'—that is front-loaded and free of any filler. It is appropriately sized for the simplicity of the operation.

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?

The schema and annotations provide rich structured context, but the description lacks guidance on usage boundaries and does not clarify partial update semantics or the role of apply_immediately. It is minimally adequate for selecting the tool, but the agent must infer important behavioral details not supplied by the structured data.

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?

All five parameters are fully documented in the schema with descriptions, giving 100% coverage. The tool description itself adds no extra parameter semantics, so it correctly relies on the schema for meaning, meeting the baseline.

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 uses the specific verb 'Update' with the resource 'existing BIND DNS zone' and specifies 'by ID', clearly distinguishing it from create_bind_zone, delete_bind_zone, and other BIND management tools. It directly and unambiguously states what the tool does.

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 for modifying an existing zone by ID, but it provides no explicit guidance on when to use this tool versus create_bind_zone or delete_bind_zone, nor does it mention any prerequisites or alternative tools. The context is sufficient for basic selection but lacks clear exclusions.

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