create_tag

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

With no annotations, the description bears the full burden of behavioral disclosure. It provides meaningful domain context by explaining that tags drive delay profiles, release profiles, import lists, and notification targeting, but it does not disclose duplicate-label behavior, idempotency, permissions, or return value.

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 two short sentences: the first states the action, and the second provides essential domain context. There is no filler, and the key action is front-loaded.

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?

The tool is simple with one documented parameter and no nested objects or output schema. The description explains the role of tags in the system, which is enough for an agent to understand the operation, though it could mention what the response contains or duplicate behavior.

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 schema already provides 100% coverage for the single 'label' parameter with a clear example ('4k' or 'kids'). The description adds no additional parameter-level meaning, so the baseline score of 3 is appropriate.

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 opens with the unambiguous verb-object pair 'Create a tag' and then explains why tags matter, referencing profiles and targeting. This distinguishes it from sibling tools like update_tag, delete_tag, and list_tags through the explicit create action.

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?

The description implies usage: use this when you need to create a new tag. However, it does not explicitly state when not to use it or contrast it with update_tag or delete_tag, leaving the selection reasoning mostly to the agent.

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