create_dns_credential

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It does well by warning that credentials will be visible in the AI conversation context, which is a critical side effect, and it explains the account/auth requirements. It does not mention overwrite behavior or validation details, but the security and access disclosures go beyond the bare minimum.

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 compact and front-loaded: the purpose appears first, followed by the important privacy warning and a concise access note. Every sentence contributes useful information without unnecessary elaboration.

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 two-parameter creation tool with no output schema and no annotations, the description covers the core purpose, critical privacy implications, and access requirements. It could be slightly stronger by noting what a successful call returns or how this step connects to later verification tools, but overall it is sufficient for correct invocation.

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 already documents both required parameters fully, including provider examples and the format for credentials as key-value pairs. The description adds little parameter-specific meaning beyond what the schema provides, so the baseline of 3 applies.

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 opens with a specific verb ('Store'), a clear resource ('DNS provider credentials'), and a purpose ('automated domain verification'). It clearly conveys what the tool does, though it does not explicitly differentiate it from sibling tools like connect_dns_provider or connect_cloudflare.

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 clear context for use: storing DNS provider credentials for automated domain verification. It also provides explicit access prerequisites and authentication steps. However, it does not specify when not to use this tool or point to alternatives like list_dns_credentials or verify_domain_with_credentials.

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