labels_create_label

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

With no annotations, the description must disclose behavioral traits. It only states creation without mentioning side effects, authorization needs, or error behavior (e.g., duplicate name). This is insufficient for an agent to understand the tool's impact.

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 only one sentence, which is concise, but it lacks structure and important details. It front-loads the action but omits parameter context and usage notes, making it under-specified for a tool with multiple optional parameters.

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 tool has 4 parameters, no schema descriptions, no annotations, and an output schema (not shown), the description is insufficient for complete understanding. An agent would lack crucial information about parameter formats, return values, and when to use this 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?

The input schema has 0% description coverage, and the description does not explain any parameters (name, icon, color, description). The agent receives no additional meaning beyond the bare schema definition, which lacks constraints or formats.

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 states the action clearly: 'Create a new label'. It mentions the specific WebSocket endpoint, which adds technical context. It is easily distinguishable from sibling tools like 'labels_delete_label' or 'labels_update_label', but does not explain what a label represents in the system.

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 is provided on when to use this tool versus alternatives, such as reusing existing labels. There is no mention of prerequisites or conditions under which creation would be inappropriate.

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