create_attachment_action

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

No annotations are provided, so the description carries full burden. It states 'create' implying a write operation but doesn't disclose behavioral traits like required permissions, whether this is idempotent, rate limits, or what happens on success/failure. The description is minimal and lacks essential context for a mutation tool.

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, efficient sentence with zero waste. It's appropriately sized and front-loaded, directly stating the tool's function without unnecessary elaboration.

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 mutation tool with 3 parameters, no annotations, and no output schema, the description is incomplete. It doesn't explain what an attachment action is, what the tool returns, error conditions, or how it differs from related tools, leaving significant gaps for an AI agent to understand proper usage.

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?

Schema description coverage is 67%, with the 'inputs' object having detailed parameter descriptions but 'type' and 'messageId' lacking context. The description adds no parameter semantics beyond what the schema provides, so it meets the baseline of 3 given moderate schema coverage but doesn't compensate for gaps.

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 tool creates a new attachment action in Webex, which is a clear verb+resource combination. However, it doesn't specify what an 'attachment action' is or differentiate it from sibling tools like create_message or edit_message, leaving the purpose somewhat vague.

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. With siblings like create_message and edit_message that might involve attachments, the description offers no context about prerequisites, appropriate scenarios, or exclusions for this specific attachment action creation.

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