get_alias

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

Annotations already cover readOnlyHint, destructiveHint, idempotentHint, and openWorldHint. The description adds that lookup is by local part, which is useful but does not explain return behavior, error handling, or edge cases, so it meets the baseline with 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?

Single sentence is appropriately concise for a simple read operation. Front-loaded with verb and resource. Could be slightly more descriptive without being verbose, but no wasted words.

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?

Despite rich annotations and two parameters, the description does not explain what 'alias details' includes or the output format. With no output schema, users are left guessing the return structure. Adequate but not complete for a read tool.

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 description must compensate. It explains that 'target' is the local part, but does not mention the optional 'domain' parameter or provide additional context on format or constraints. Only one parameter is partially explained.

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 'Get alias details by local part,' specifying the verb (Get) and resource (alias details) with a key parameter (local part). It distinguishes from sibling tools like list_aliases or create_alias, but assumes knowledge of what 'local part' means.

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 guidance on when to use this tool versus alternatives like list_aliases or get_domain. It does not mention when-not to use it, prerequisites, or conditions that favor this tool over siblings.

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