DNS_restoreDNSSnapshotV1

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

Without annotations, the description must convey behavioral traits. It indicates a mutation (restore/revert) but does not disclose side effects, required permissions, rate limits, or whether the operation is destructive or reversible. The basic intent is clear, but depth is lacking.

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-loaded with the primary action, and contains no redundant information. Every word earns its place, making it efficient and clear.

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 no output schema, the description adequately explains the purpose but lacks details on prerequisites (e.g., need existing snapshot), return values, or idempotency. It does not connect to sibling tools like DNS_getDNSSnapshotListV1 for discovering snapshots, leaving some gaps.

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 additional meaning beyond the schema's 'Domain name' and 'Snapshot ID'. While the schema suffices, the description does not enhance parameter understanding.

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 explicitly states 'Restore DNS zone to the selected snapshot' and 'revert domain DNS to a previous configuration', clearly identifying the verb (restore), resource (DNS zone/snapshot), and action (revert). It distinguishes from sibling tools like DNS_resetDNSRecordsV1 and DNS_updateDNSRecordsV1, which perform different operations.

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 says 'Use this endpoint to revert domain DNS to a previous configuration', which provides clear context for when to use. However, it does not explicitly state when not to use or compare to alternatives like DNS_getDNSSnapshotListV1 for listing snapshots first, leaving some ambiguity.

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