DNS_getDNSSnapshotListV1

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

No annotations are provided, so the description must carry the full burden. It discloses the operation as a read (retrieve) but lacks details on side effects, authentication requirements, rate limits, or any behavioral traits beyond the basic action. The description is minimal, focusing only on purpose.

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 consists of two sentences (17 words) with no wasted words. It front-loads the action ('Retrieve DNS snapshots') and includes a usage directive. It is appropriately sized for a simple tool.

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 list operation with one required parameter and no output schema, the description provides sufficient context: what it does and when to use it. It does not explain the snapshot concept or response format, but given simplicity, it is mostly 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?

The schema has one required parameter 'domain' with description 'Domain name'. The description adds context by stating 'DNS snapshots for a domain,' reinforcing the parameter's role. With 100% schema coverage, the description adds marginal value but is adequate.

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 (retrieve) and resource (DNS snapshots for a domain) with explicit mention of viewing available backup points for restoration. It effectively distinguishes from sibling tools like DNS_getDNSSnapshotV1 (single snapshot) and DNS_restoreDNSSnapshotV1 (restoration).

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 a clear usage context: 'use this endpoint to view available DNS backup points for restoration.' It implicitly indicates when to use (before restoration) but does not explicitly state when not to use or contrast with alternatives, though sibling differentiation is clear from names.

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