Create Discord scheduled event

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

Annotations already declare this as a non-read-only, non-idempotent, open-world, non-destructive mutation. The description adds the channelId/location entity-type distinction, but it does not explain permissions, the confirm parameter, side effects, or rate limits beyond what annotations provide.

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 two front-loaded sentences with no filler, so it is structurally clean. However, it is arguably too terse for a 13-parameter creation tool, even if every sentence earns its place.

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?

This is a complex mutation with 13 parameters, nested objects, and no schema parameter descriptions. The description covers only the channel/location split and leaves most required and optional input semantics unexplained; the output schema relieves only the return-value burden.

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% across 13 parameters, and the description only explains channelId and location. Required parameters such as guildId, name, scheduledStartTime, entityType, plus confirm, privacyLevel, entityMetadata, image, reason, and scheduledEndTime are left undocumented.

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 gives a specific verb and resource: 'Create a Discord scheduled event.' It is clear what the tool does and the verb distinguishes it from list/update/delete siblings, but it does not explicitly route the agent away from those alternatives.

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?

It gives concrete guidance for choosing between channelId and location based on event type: voice/stage vs external. That is useful selection context, though it does not state when not to use this tool or compare it directly with sibling tools.

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