create_tag

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

With no annotations provided, the description carries the full burden of behavioral disclosure, but it only restates the action. It does not mention any side effects, validation rules (e.g., unique tag names), required permissions, or return behavior, which is a significant gap for a create operation.

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, clear sentence with no filler words. It is appropriately sized for a simple create operation and is front-loaded with the essential action, making every word earn its place.

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 low complexity (2 parameters, 100% schema coverage) and no output schema, the description is adequate at a basic level but lacks context about the tag's role in the system or whether the created tag is returned. It does not mention how tags relate to tasks or any unique constraints, leaving gaps for the agent.

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 100%, with both 'name' and 'color' already described in the input schema. The tool description adds no additional parameter meaning, so it does not exceed the baseline of 3 set by the rubric for high schema 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 tag' uses a specific verb and resource, clearly stating the action. It distinguishes from siblings like update_tag, delete_tag, and list_tags by specifying the create operation, so there is no ambiguity about what the tool does.

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?

There is no guidance on when to use this tool versus alternatives like update_tag or add_tag_to_task. The description merely restates the action without explaining prerequisites, use cases, or exclusions, leaving the agent without contextual decision support.

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