manage_alias_addresses

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

Annotations already indicate mutation (readOnlyHint=false), idempotency (idempotentHint=true), and non-destructiveness (destructiveHint=false). The description adds no extra behavioral context beyond 'existing alias', which is already implied. It does not contradict annotations, so a neutral score is appropriate.

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 a single, focused sentence of nine words. It is front-loaded, contains no filler, and every word adds value.

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 tool, the description sufficiently covers the operation and target. The presence of an output schema reduces the need to explain return values. However, it could be more complete by noting when to prefer this over update_alias, but that is not essential for functionality.

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 provides 100% coverage with clear descriptions for all three parameters (alias_id, action, addresses). The description adds no additional parameter details, but the schema does the heavy lifting, so the baseline of 3 is appropriate.

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 'Add or remove addresses from an existing alias' uses a specific verb phrase (add or remove) and names the resource (addresses on an alias). It clearly distinguishes from sibling tools like create_alias and delete_alias, and implies a sub-operation on an existing alias rather than general update.

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 guidance on when to use this tool versus update_alias, which could also modify alias properties. The description implies usage through the name but does not state exclusions or alternatives, so an agent may struggle to choose between them.

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