send_webex_message

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

No annotations are provided, so the description must fully disclose behavior. It mentions the return type and parameter details but lacks information on rate limits, synchronous behavior, or error conditions. The description is basic and does not go beyond functional parameter descriptions.

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 a concise opening sentence, a clear parameter list, a return value note, and examples. It is not overly verbose, though the parameter list in text format could be slightly cleaner.

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 8 parameters, no output schema, and absence of annotations, the description covers the main functionality and parameters well. However, it lacks guidance on combining content types (e.g., text vs. markdown) and does not differentiate from sibling tools that handle similar tasks with specific features.

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 0% description coverage, so the description compensates by explaining each parameter's purpose, including mutual exclusivity of targeting parameters and specific use cases (e.g., 'parent_id' for threaded replies). Examples further clarify usage.

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 'Send a message to a Webex room or person' with a specific verb and resource. It covers the main parameters but does not explicitly differentiate from sibling tools like send_webex_adaptive_card or send_webex_message_with_mentions.

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 by noting the mutual exclusivity of room_id versus to_person_id/to_person_email and provides examples. However, it does not explicitly state when to use this tool over alternatives like send_webex_adaptive_card or send_webex_message_with_mentions.

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