create_label

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

With no annotations, the description carries the burden of behavioral disclosure. It clearly states the mutation (create) and notes the return value ('Returns: Created Label object'), but lacks details on side effects, validation rules, uniqueness, or permission requirements. This is adequate but not thorough.

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 structured as a clear docstring with a title, args list, and returns line. It is concise, with no extraneous information, and every sentence adds value. The parameter list is organized and easy to parse.

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 8-parameter complexity and lack of annotations, the description covers all parameters and states the return type. It does not mention when to use, edge cases, or constraints like required permissions, but these are secondary for a simple create operation. Overall, it is reasonably complete.

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 description provides meaningful context for every parameter beyond the schema's type-only definitions. For example, it explains 'project_id: UUID of the project', 'color: Label color (hex color code)', and 'parent: UUID of the parent label (for nested labels)'. This fully compensates for the 0% schema description coverage.

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 'Create a new label' uses a specific verb and resource, clearly distinguishing it from sibling operations like retrieve_label, update_label, and delete_label. The action is unambiguous and correctly named.

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 update_label or delete_label. There is no mention of prerequisites, intended use cases, or exclusions, leaving the agent without context for tool selection.

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