discord_send

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

With no annotations provided, the description carries the full burden. It omits critical behavioral details, such as whether the bot must be present in the server, any permission requirements, rate limits, side effects like message character limits, or what happens if a channel name is missing. The description does not compensate for the missing annotations.

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 very concise (one sentence), which is good for efficiency. However, it is under-specified for an AI agent; conciseness should not come at the cost of completeness. The structure is minimal but acceptable for a simple tool, though important details are missing.

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 three required parameters, no output schema, and no annotations, the description is insufficient. It does not explain the return value, error behavior, or edge cases like empty arrays or nonexistent channels. A more complete description would include usage examples or mention what the tool returns upon success or failure.

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 0%, meaning the description adds no information about the parameters. The parameter names (guildId, channelNames, message) are not explained—e.g., channelNames can be a string or array, but this nuance is absent. The tool description should clarify the expected format and usage of each parameter, but it does not.

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 verb 'sends' and resource 'message to one or more Discord text channels by name in a server'. It specifies the channel identification method ('by name'), which distinguishes it from sibling tools like discord_send_webhook_message. This is a specific and unambiguous purpose.

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 given on when to use this tool versus alternatives, such as when to use a webhook vs direct message sending. There is no mention of prerequisites like bot permissions or server membership, nor any when-not-to-use conditions. The description only states the action without contextual usage advice.

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