Delete domain pointer

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

Annotations already declare destructiveHint=true and idempotentHint=true, so 'Destructive:' largely restates structured data. The description does add real value with the actionable workflow 'confirm with the user before calling,' but says nothing about side effects, reversibility, or what happens on a missing pointer.

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, front-loaded with the operation and followed immediately by the safety instruction. The 'Destructive:' label duplicates the annotation, which is slight waste, but nothing is bloated.

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 two-parameter, fully documented destructive mutation with rich annotations, the description covers the essentials plus the confirmation requirement. It omits prerequisites and post-deletion effects (e.g., what happens to mail routed via that pointer), which would be the natural remaining gaps.

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 description coverage is 100% and both parameters carry clear descriptions ('the target domain the pointer points at', 'the pointer domain to remove, e.g. alias.com'). The description adds no syntax, format, or constraint detail beyond the schema, so the baseline 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?

States a specific verb and resource ('Removes a domain pointer from a domain'), which is distinct from the sibling delete_domain (which removes an entire domain) and from list_domain_pointers / create_domain_pointer. It does not explicitly name those siblings to route the agent, so it falls short of a 5.

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 guidance on when to use this versus delete_domain or how it relates to the pointer lifecycle (e.g., whether the pointer must exist first). The only instruction is a confirmation protocol, which is behavioral rather than selection guidance.

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