List DNS Zone RRSets

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

Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true, and openWorldHint=true. The description adds the filtering capability but does not disclose pagination behavior or rate limits. It is consistent with annotations but adds little beyond them.

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?

Single sentence, front-loaded with key action and resource, no redundant words. Highly concise and structured effectively for quick parsing.

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?

The tool has 7 parameters, 1 required, and no output schema. The description is too brief; it does not explain the concept of RRSets, the zone context, pagination behavior, or return value expectations. For a tool of this complexity, more context is needed for an agent to use it correctly.

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%, so the schema already documents all parameters. The description mentions filtering by name, type, or labels, which aligns with parameters. However, it does not explain the required id_or_name parameter or pagination parameters. Baseline 3 is appropriate given high 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 clearly states the verb 'List' and the resource 'all RRSets in a DNS zone', distinguishing it from mutation and single-get siblings. It also mentions optional filtering, which adds specificity. However, it could explicitly separate from other list tools (e.g., hetzner_list_zones) but the resource is specific enough.

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 gives a clear context for use (listing/filtering RRSets) but does not provide explicit when-to-use vs. alternatives (e.g., use get for a single RRSet) or mention prerequisites (e.g., need zone id). Lacks exclusions or comparative guidance.

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