create_label

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

No annotations are provided, so the description must fully disclose behavior. It only mentions nesting but fails to describe important behaviors such as whether duplicate labels are allowed, nesting depth limits, character restrictions, case sensitivity, or authentication needs. For a create tool, this is insufficient.

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 extremely concise with two sentences. The first sentence states the core purpose, and the second adds a valuable nesting tip. No unnecessary 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?

Given 5 parameters with 0% schema description coverage and no output schema, the description is severely incomplete. It only addresses one parameter and omits critical details about visibility settings and optional account/password fields. The tool's behavior regarding creation failure modes, uniqueness, and return value is not mentioned.

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 must add meaning for all parameters. It only explains the 'name' parameter with nesting syntax; the other four parameters (label_list_visibility, message_list_visibility, account, password) are left unexplained. This provides almost no value 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 the verb 'Create' and the resource 'label'. It also provides a specific usage tip about nesting with '/', which distinguishes it from sibling tools like delete_label or update_label.

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 gives a helpful nesting hint but does not explicitly state when to use this tool versus alternatives like update_label (for modifying an existing label) or list_labels (to view labels). No exclusion or when-not guidance is provided.

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