Edit Welcome Screen

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

Annotations indicate non-read-only, idempotent, open world, and non-destructive. The description adds meaningful context such as required permissions and prerequisite (Community features), plus return type ('Updated welcome screen settings'), which goes beyond 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 well-structured with a clear main sentence, a prerequisite line, a bulleted Args list, and a Returns line. It is mostly concise but the Args section repeats schema information, making it slightly longer than necessary.

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 tool's complexity (4 parameters, 1 required), no output schema, and moderate annotations, the description covers prerequisites, permissions, parameter details, and return value. It is complete for an agent to invoke correctly.

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 100%, so the description does not need to add much. The description restates parameter info in a structured list, adding minor formatting details but essentially duplicating the schema. This is adequate but not extra valuable.

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 'Edit the welcome screen configuration for a server.' This is a specific verb-resource combination and distinguishes from sibling tools like discord_get_welcome_screen and other edit tools.

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 usage context: requires Community features and MANAGE_GUILD permission. However, it does not mention when not to use it or suggest alternatives, though the sibling list includes get and other edit tools.

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