Change DNS Zone RRSet Protection

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

Annotations already indicate idempotency and safety (not read-only, not destructive). The description adds the behavioral context that this tool guards against accidental changes, which aligns with the idempotentHint. No contradictions; the description complements the annotations.

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 concise sentence, front-loading the action and purpose. Every word adds value; no redundancy.

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 simple protection toggle tool, the description covers the core functionality. However, it lacks any mention of return values (no output schema) or prerequisites like permissions. Given the low complexity and presence of annotations, it is minimally adequate but not fully complete.

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 parameters are described in the schema (100% coverage). The description adds clarity for the 'change' parameter, explaining its effect. The other parameters (id_or_name, name, type) are described sufficiently in the 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 clearly states the action: 'Enable or disable change protection on an RRSet'. It specifies the resource (RRSet) and the operation (toggle protection), distinguishing it from sibling tools like 'change_zone_protection' which target different resources.

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 mentions the purpose ('guard against accidental modification or deletion'), implying when to use it, but provides no explicit guidance on when not to use it or alternatives. The sibling tools provide similar protection for other resources, but the description does not differentiate or set usage boundaries.

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