create_label

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

The description aligns with annotations (readOnlyHint=false, destructiveHint=false) but adds no further behavioral context. It does not disclose side effects, permission requirements, or response behavior. The description contributes no value beyond what annotations already indicate.

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 a single, focused sentence with no redundancy. It is front-loaded with the primary action and object, making it highly concise 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?

For a tool with seven parameters, no output schema, and zero schema descriptions, the description is severely under-specified. It fails to address parameter meaning, expected behavior, or return values, leaving the agent with insufficient information for correct invocation beyond the schema's raw parameter names.

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?

With schema description coverage at 0%, the description should compensate by explaining parameter meanings. However, it only mentions 'project' and 'label' generically, offering no insight into the seven parameters (name, color, parent, project_id, sort_order, external_id, external_source). Required parameters project_id and name are not elaborated.

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 uses specific verb 'create' with resource 'label' and scope 'in a project', clearly distinguishing it from sibling tools like list_labels, retrieve_label, update_label, and delete_label. It unambiguously states the tool's function.

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. There is no mention of prerequisites, when not to use it, or references to update_label/delete_label for modification or removal. The description simply states the action without contextual direction.

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