remove_address_list_entry

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

Annotations already declare destructiveHint and idempotentHint, but the description adds valuable context by noting that removing a hostname entry also clears dynamic entries derived from it. This goes beyond the annotations and alerts the agent to a cascading effect, which is important for decision-making.

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 two sentences: the first states the core action and identification, the second adds a relevant note. It is front-loaded, concise, and free of filler. Every word earns its place.

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 is a simple removal with a required family parameter and an output schema. The description covers the purpose and a key side-effect, but omits clarification on family, address format, and any prerequisites (like device). Given the output schema exists, return values are not needed, but parameter semantics are incomplete, leaving the overall context only partially adequate.

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 0%, so the description should compensate by explaining the parameters. It mentions 'list name and address' but does not clarify the 'family' parameter, which is required and has an enum. It also does not explain address format or the relationship between family and the address. This leaves the agent guessing about required inputs.

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 action ('Removes an address list entry') and the identification method ('by list name and address'), distinguishing it from sibling tools like create, update, list, and get. It is specific and unambiguous.

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 purpose implies when to use it (to delete an address list entry), but there is no explicit guidance on when to prefer it over alternatives, nor any mention of conditions like 'use this only when you need to remove an entry permanently'. The note about hostname entries hints at a side-effect but does not frame usage context.

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