Get DNS configuration status

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is covered. The description adds genuinely useful context beyond that: a concrete rate limit (100 requests / 10 seconds per shop) and the fact that the returned configuration is cached rather than freshly resolved.

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?

Two short sentences with no padding. The rate-limit note is placed first rather than the purpose statement, which is slightly less front-loaded than ideal, but the content is tight overall.

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 parameterless read-only tool with annotations covering the safety profile, the description says enough to call it correctly. With no output schema, more detail on what 'record status' contains or how stale the cache may be would help, but the essentials are present.

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 coverage is 100% and the single 'account' parameter is documented in the schema as a private shop profile label. The description adds nothing about the parameter, but with full schema coverage the baseline 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?

States a specific verb and resource: 'Returns the cached DNS configuration and record status for the shop's custom domain.' The word 'cached' usefully separates it from a live validation. It does not, however, name or distinguish itself from the sibling validate_dns, which an agent could plausibly confuse it with.

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?

There is no explicit guidance on when to call this versus validate_dns, which is the obvious alternative in the sibling list. No prerequisites or exclusions are given; the agent must infer usage from the tool name alone.

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