discord_edit_webhook_message

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

Adds useful behavior beyond annotations: 'Replaces the provided fields' indicates partial replacement rather than full overwrite, and 'Requires the original webhook token' names the authentication prerequisite. Annotations already provide idempotent/read-only/destructive hints, and the description does not contradict them.

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?

Four short sentences, front-loaded with the core operation and then the required context. There is no filler or unnecessary repetition of schema details; the token emphasis earns its place as an auth requirement.

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 tool with three required parameters and a rich input schema, the description covers the key operational facts: target resource, replacement behavior, authentication need, and return behavior. It could be more complete with explicit sibling exclusions, but it is sufficient for correct invocation.

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 100%, so the individual parameter documentation carries the meaning. The description adds context about replacement semantics and token requirement, but does not explain specific parameters beyond what the schema already provides.

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?

Describes a specific action—editing a webhook-sent message using the webhook's ID and token—and clarifies it operates on a previously sent message. This distinguishes it from siblings like discord_edit_message and discord_edit_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?

Gives a clear use context: edit messages that were sent through a webhook, and states the prerequisite that the original webhook token is required. It does not explicitly name alternatives or exclusion cases, but the webhook-specific scoping makes routing unambiguous.

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