discord_send_webhook_message

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 context. It only states the basic action and does not disclose error handling, rate limits, or capability to send embeds. This is insufficient for an agent to understand consequences.

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, well-structured sentence that efficiently communicates the core purpose without extraneous words. It is appropriately front-loaded.

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 six parameters, lack of annotations, and sibling tools, the description fails to provide adequate context. It does not explain optional parameters like threadId, username, or avatarURL, nor does it clarify the need for a pre-existing webhook.

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 zero description coverage, and the tool description adds no explanation for any of the six parameters. The agent must infer meaning from parameter names alone, which is inadequate for correct 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 the action (sends), the resource (message), the method (using a webhook), and the destination (Discord channel). It effectively distinguishes from sibling tools like discord_send which likely sends without a webhook.

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 (e.g., discord_send), nor does it mention prerequisites such as having a webhook ID and token. An agent cannot determine the appropriate context from this description alone.

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