create_alias

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

No annotations are provided, so the description carries the full burden. It explains what the tool does and parameter behaviors (e.g., default alias name, map_working_directory). However, it lacks disclosure of potential side effects, overwrite behavior, or error conditions, which is a gap for a mutation tool.

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 has a clear structure with an Args section and is front-loaded with the purpose. However, it is slightly verbose with line breaks and could be more concise without losing clarity.

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?

Given the complexity of 4 parameters and no annotations, the description covers parameter semantics thoroughly. It does not explain prerequisites (e.g., instance must exist) but assumes some Multipass knowledge. Since output schema exists, return values are not required.

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 0%, so the description fully compensates. It explains all four parameters: instance (name of instance), command (command to execute), alias_name (optional, defaults to command name), map_working_directory (auto-maps path if True). This adds significant meaning beyond the schema.

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 'Create a Multipass alias to be executed on a given Multipass instance.' It uses a specific verb ('Create') and resource ('Multipass alias'), and distinguishes from sibling tools like list_aliases and remove_alias.

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 description implies usage when one wants to create an alias but does not provide explicit guidance on when to use this tool versus alternatives, nor does it mention prerequisites or context. With many sibling tools, some 'when to use' context would be helpful.

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