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

Annotations already declare readOnlyHint=false, idempotentHint=false, and destructiveHint=false. The description adds useful context by stating the required scope (domains:write) and explicitly noting the operation mutates server state. It does not describe side effects like overwriting the existing SPF record, but this is partially covered by the annotations.

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 short and well-structured with labeled lines for HTTP method, category, scopes, and mutation effect. It is front-loaded with the core action and contains no filler.

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 description is incomplete for actually invoking the tool because the request body schema is not statically declared and no example or field list is provided. An agent can select the tool but cannot reliably construct a valid update payload based on this description alone.

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 documents id as a path parameter and body as an untyped object with additionalProperties allowed, but the body description explicitly says 'Schema not statically declared.' The tool description adds no parameter details, example payload, or guidance on what fields the SPF update body should contain, which is a critical gap for a mutation endpoint.

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 states a clear verb ('Update') and resource ('spf') and gives the HTTP path, so an agent can distinguish it from the sibling GET SPF endpoint. It is concise but does not elaborate on what updating an SPF record entails.

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?

No explicit when-to-use or when-not-to-use guidance is provided. The PATCH method and 'Mutating' note imply this is for changing an existing SPF configuration, but there is no mention of reading the current SPF first, prerequisites, or how this differs from other domain update tools.

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