Create Tag

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

Annotations already declare readOnlyHint=false and destructiveHint=false, so the description adds no extra behavioral context. It does not disclose side effects, permission requirements, or error conditions (e.g., duplicate names). The description is silent on anything beyond the act of creation.

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 extremely concise at five words, which is efficient, but it is under-specified. It lacks the substance needed to be useful, so while there is no verbosity, the brevity works against its effectiveness. It is not well-structured for comprehension beyond stating the obvious.

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?

With a complex nested input schema and an output schema present, the description is highly incomplete. It fails to explain how to construct the request, what the response contains, or any constraints. For a tool with such a detailed schema, this level of description is inadequate.

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 has a nested body object with multiple optional fields (color, match, is_inbox_tag, etc.), and schema description coverage is 0%. The description does not explain the body parameter, its structure, or the meaning of any of these fields, leaving the agent without semantic guidance beyond raw schema types.

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 states the verb 'create' and resource 'tag', which clearly distinguishes it from sibling operations like list, get, update, and delete. It is specific enough for an agent to know the tool's function, though it does not elaborate on scope or nuances.

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, such as needing an existing tag or when to prefer create_tag over update_tag or bulk_edit_tags. The description is purely functional with no contextual direction.

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