add_webex_membership

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

No annotations are provided, so the description carries the full burden. It mentions a return format but does not disclose behavioral traits such as idempotency, permission requirements, rate limits, or side effects like what happens if the membership already exists. The note about success/error is minimal.

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 structured with an Args/Returns docstring, which is clear but slightly verbose. The essential information is presented upfront, but the list format could be more concise. Every sentence contributes, but the return description is generic.

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 no output schema, no annotations, and 4 parameters with zero schema coverage, the description should be more complete. It misses important details like error handling, idempotency, and whether the operation is reversible. The return format description is too vague to be fully useful.

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?

With 0% schema description coverage, the description adds value by explaining each parameter, including the mutual exclusivity of person_id and person_email, and the optional is_moderator. However, it lacks format constraints or examples that could further aid understanding.

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 starts with 'Add a person to a Webex room,' which clearly states the action and resource. It distinguishes from sibling tools like 'create_webex_room' but does not differentiate from 'add_webex_space_membership' or 'add_webex_team_membership', though the mention of 'room' provides some context.

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 explicit guidance on when to use this tool versus alternatives. There is no mention of prerequisites, exclusions, or when not to use it. The description only lists parameters without usage context.

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