Add Tag

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

No annotations are present, so the description must carry the full burden of behavioral disclosure. It only says 'Creates' without mentioning side effects such as uniqueness constraints, potential errors, or idempotency, leaving uncertainty about the mutation behavior.

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, concise sentence that immediately states the action and purpose. It is front-loaded with the verb and contains no superfluous information.

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 simple create operation, the description is adequate but lacks details about error conditions, potential conflicts (e.g., duplicate tag names), or the outcome (e.g., return value). It does add some context by mentioning assignability to monitors, but it is not fully 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 input schema fully describes both parameters (name and color), providing clear definitions. The tool description adds no additional parameter information beyond what is already in the schema, so the baseline score applies.

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?

Description clearly states the tool creates a new tag, using a specific verb and resource. It implicitly distinguishes from sibling tools like listTags and deleteTag.

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?

It is evident that this tool is for creating tags, and the context 'that can be assigned to monitors' hints at its application. However, it does not explicitly state when to use it over alternatives or exclude certain scenarios, though the simplicity of the operation makes this acceptable.

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