discord_set_channel_permissions

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

There are no annotations, so the description must carry the full behavioral burden. 'Set' implies mutation, but it does not disclose whether it fully replaces the overwrite, how it interacts with existing allow/deny entries, what permissions are required, or whether the overwrite affects target-specific or server-wide defaults.

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 a single sentence with no filler, and the core resource ('channel') and operation ('set permission overwrites') are front-loaded. It is concise, though perhaps at the expense of necessary behavioral and parameter detail.

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?

With 6 parameters, no annotations, no schema descriptions, and an output schema that is not shown, a single sentence is not enough. An agent needs to know allowed target references, allowed permission names, allow/deny semantics, and the effects of omitting either option to use this tool 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 description coverage is 0%, so the description must compensate, but it does not. It adds some meaning to 'target' by mentioning @everyone, a role, or a member, but it does not explain the target format, valid allow/deny strings, the meaning of null defaults, or how guild_id/channel_id relate.

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 states a clear action — setting permission overwrites on a channel — and names the three target categories: @everyone, a role, or a member. It is specific enough to distinguish from the get-side siblings like discord_get_channel_permissions, but it does not explicitly contrast itself with discord_set_role_permissions or discord_get_channel_permissions.

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 no guidance about when to use this tool versus related tools such as discord_get_channel_permissions or discord_set_role_permissions. There is no mention of prerequisites, requirements, or when not to use it.

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