get_message_event

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It does not explicitly state that this is a read-only operation, nor does it describe potential errors, rate limits, or other side effects. The only behavioral hint is mention of the raw webhook payload in the return, which partially discloses the response format.

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, front-loaded sentence with zero wasted words. It conveys the action, resource, and a distinguishing detail efficiently.

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 that an output schema exists (not shown but indicated), the description needn't explain return values, and it does hint at the payload inclusion. However, it lacks usage context, such as when to use this tool vs. listing messages, and it doesn't clarify behavior on missing events or error conditions. For a simple read operation this is adequate but not rich enough for complete guidance.

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 coverage is 0%, so the description must compensate. It says 'by id,' which clearly implies the single event_id parameter is the identifier, but it doesn't elaborate on the parameter's meaning, format, or any constraints beyond being an integer. This adds some meaning but not enough to fully compensate for the complete absence of parameter documentation in the schema.

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 a specific verb (Get) and resource (one stored message event) and adds the critical detail that it includes the raw webhook payload. It clearly differentiates from sibling list_messages, which implies listing, without needing to name it explicitly.

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 on when to use this tool versus alternatives. It does not mention exclusions, prerequisites, or scenarios where a different tool (e.g., list_messages) would be more appropriate. The agent must infer usage from the name and context.

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