create_a_label

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

No annotations are present, and the description merely states a create action. It does not disclose permissions, scope (global vs. scoped), side effects, or return behavior beyond the bare 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?

Overly brief single sentence that provides no structure or additional information; conciseness sacrifices utility.

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 presence of many sibling label-related tools, the description is incomplete. It does not clarify how this tool relates to labeling contacts or conversations, nor what the label entity contains.

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?

Input schema has zero properties, so description carries full burden. It adds no meaning beyond the tool name, failing to explain what constitutes a label or required fields.

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?

Description is a tautology: 'Create a label' restates the tool name without specifying what kind of label or differentiating from sibling tools like contact_add_labels or conversation_add_labels.

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 vs. alternatives, no prerequisites, no exclusions. The description provides no usage context.

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