Restore DNS Snapshot

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

With no annotations provided, the description carries the burden of disclosing behavioral traits. It fails to mention that restoring a snapshot will overwrite current DNS records, any required permissions, or the irreversible nature of the operation. The single sentence only restates the action.

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 with no unnecessary words, making it easy to parse. However, its brevity leaves out critical information, but that is more a completeness issue than a conciseness issue.

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?

As a restore operation with no annotations and no output schema, the description is under-specified. It does not explain what happens to existing DNS records, prerequisites like needing to list snapshots first, or what the response contains. This is a significant gap for a mutating tool, so completeness is low.

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?

Both parameters (domain and snapshot_id) are already described in the input schema with 100% coverage. The description adds no additional meaning beyond restating that a domain is involved, and it does not clarify how to obtain a valid snapshot_id (e.g., from dns_get_snapshots). Baseline score of 3 applies due to full schema coverage.

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 'restore' and names the resource 'DNS snapshot for a domain,' clearly indicating this tool restores a DNS snapshot to a domain. It distinguishes from related siblings like dns_get_snapshot/dns_get_snapshots (view only) and vps_restore_snapshot (VPS snapshots) through the 'DNS' and 'restore' wording.

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 provides no guidance on when to use this tool versus alternatives such as dns_get_snapshots/dns_get_snapshot for viewing snapshots, or vps_restore_snapshot for VPS snapshots. It merely states the action without any context or exclusions.

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