Create Contact Folder

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only says 'personal' folder, but does not mention side effects, permissions, return values, or any requirements. For a create operation, this is a minimal disclosure and misses opportunities to clarify behavior beyond the obvious action.

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: an English statement and a Chinese translation. Both are concise, front-loaded with the main action, and contain no redundant information. It is appropriately sized for the tool's simplicity.

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 simple with one parameter and no output schema, so the description is minimally sufficient. However, the lack of annotations means more context would be helpful, such as prerequisites or when to use it. The current description is adequate but does not exceed expectations for a simple create 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 description coverage is 100% for the sole parameter displayName, which is clearly described as 'Contact folder name.' The description adds no extra parameter information, but the baseline of 3 applies because the schema already handles the semantics.

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 personal contact folder' with a specific verb and resource, distinguishing it from sibling tools like contacts_create (creating a contact) and contacts_delete_folder (deleting a folder). The Chinese intents are an additional language clue, enhancing clarity.

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 the tool is used when creating a contact folder, but it does not explicitly discuss alternatives or provide exclusion criteria. No guidance is given on when to use this versus other folder-related tools, though the name and context make it somewhat obvious.

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