discord_copy_permissions

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

Annotations already declare destructiveHint=true and idempotentHint=true. The description adds behavioral details: 'The target's existing overwrites are overwritten' (aligning with destructiveHint) and 'Returns a confirmation.' It also specifies the Manage Roles permission requirement, providing additional context 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 three concise sentences: first sentence states the action, second sentence clarifies the effect, and third sentence provides permission and result. No wasted words, front-loaded with essential information.

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 (copying permissions), the description covers the core behavior, effect, permission, and return value. It lacks explicit mention of error scenarios or scope (e.g., role vs member overwrites), but annotations compensate for some gaps (e.g., destructiveHint). Overall sufficiently complete for an AI agent.

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% with clear parameter descriptions for source_channel_id, target_channel_id, and reason. The description does not add new parameter meaning beyond what the schema provides, so a baseline score of 3 is appropriate.

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 ('replace the target channel's permission overwrites with a copy of the source channel's'), specifies the resource ('permission overwrites'), and distinguishes it from sibling tools like discord_lock_channel_permissions by emphasizing the copy operation.

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 mentions a required permission ('Requires the Manage Roles permission'), which is a prerequisite. However, it does not explicitly state when to use this tool versus alternatives (e.g., discord_set_role_permission or discord_lock_channel_permissions), leaving usage context implied rather than explicit.

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