DNS_restoreDNSSnapshotV1

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 implies destructive action but does not specify irreversibility, permissions, or side effects (e.g., overwriting all records). This is insufficient for a restore operation.

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, front-loading the core action and providing a brief clarification. No unnecessary words, making it highly concise and well-structured.

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 simplicity of the tool (2 params, no output schema, no annotations), the description is minimally adequate. It explains the 'what' and 'why' but lacks details on effects and prerequisites, making it only partially 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?

Schema description coverage is 100% (both 'domain' and 'snapshotId' have descriptions). The tool description adds no extra meaning beyond the schema, so 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 clearly states 'Restore DNS zone to the selected snapshot' and explains it reverts domain DNS to a previous configuration. It uses a specific verb and resource, and distinguishes from sibling tools like DNS_getDNSSnapshotListV1 and DNS_resetDNSRecordsV1.

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 'Use this endpoint to revert domain DNS to a previous configuration,' providing context for when to use it. However, it lacks explicit guidance on when not to use it (e.g., avoiding if a full reset is desired) and does not reference alternatives like DNS_resetDNSRecordsV1.

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