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

With no annotations provided, the description carries full burden for behavioral disclosure. It states this is a creation operation (implying mutation) and mentions the return format, but lacks critical details like required permissions, whether tag names must be unique, error conditions, or side effects. The description adds minimal behavioral context beyond the obvious.

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 well-structured with clear sections for Args and Returns, and every sentence serves a purpose. It's appropriately sized for a 3-parameter creation tool, though the 'seat (account)' parenthetical could be slightly more elegant.

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 mutation nature (creation), 0% schema description coverage, and presence of an output schema (which handles return values), the description does an adequate but minimal job. It covers the basic action and parameters but lacks important context about permissions, constraints, and error handling that would be valuable for a mutation tool.

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 description explicitly lists all three parameters with brief explanations, adding meaningful context beyond the 0% schema description coverage. It clarifies that 'account_id' refers to a 'seat' and that 'tag_name' is the name to create. However, it doesn't provide format requirements, constraints, or examples for these parameters.

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 clearly states the action ('Create a new tag') and the target ('for a specific seat (account)'), providing a specific verb+resource combination. However, it doesn't differentiate from sibling tools like 'assign_tag_to_lead' or 'get_tags_for_seat', which handle related but different tag operations.

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 provides no guidance on when to use this tool versus alternatives like 'assign_tag_to_lead' (which assigns existing tags) or 'get_tags_for_seat' (which retrieves tags). There's no mention of prerequisites, constraints, or typical use cases beyond the basic action.

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