Get DNS Snapshot

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

With no annotations, the description carries the full burden, but it does clearly imply a read-only operation via the word 'Get,' which is a key behavioral trait. However, it does not disclose return format, error behavior, or any prerequisites, which could be expected for a more complex tool.

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 sentence with no extraneous words, which is highly concise and front-loaded. It effectively communicates the core function, though it could be slightly more informative without adding verbosity.

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 tool's low complexity (simple 2-parameter read operation) and the absence of an output schema, the description is minimally adequate. It clearly states what it does, but does not explain what 'details' includes or how it fits into the DNS snapshot lifecycle with sibling tools like dns_get_snapshots and dns_restore_snapshot.

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 input schema fully documents both parameters (domain and snapshot_id) with descriptions, so the schema coverage is 100%. The description's 'specific DNS snapshot' aligns with these parameters, but adds no additional meaning beyond what the schema already provides, earning a baseline score.

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 a specific verb ('Get') and identifies the resource as 'a specific DNS snapshot details,' which clearly indicates the operation is to retrieve one snapshot. This distinguishes it from the sibling tool 'dns_get_snapshots' which likely lists all snapshots, though it does not explicitly reference the sibling.

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 like dns_get_snapshots or dns_restore_snapshot. It only states what it does without any contextual advice, leaving the agent to infer its place in the workflow.

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