discord_list_channels

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

No annotations are provided, so the description carries the full burden. 'List' clearly indicates a read-only operation, but there is no disclosure about permissions, pagination, what channel data is returned, or how a possible null guild_id behaves. Basic transparency is present, but depth is thin.

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 six words and every word contributes. It is front-loaded with the action and resource, and there is no filler or repetition of the tool name.

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?

For a simple one-parameter listing tool with an output schema, the basic purpose is reasonably complete. However, with no annotations and no parameter-level help, the description leaves the optional guild_id semantics and the boundary between this and sibling tools under-explained. It is a minimum-height viable definition, with room to improve.

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% and the description adds nothing meaningful beyond the word 'guild' for guild_id. The parameter name is self-descriptive, but the null/default behavior and how the tool selects a guild are undocumented in both the schema and the description.

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 specific action ('List') and resource ('channels') with a clear scope ('in a guild'), and the word 'all' distinguishes it from targeted tools like discord_get_channel. It lacks an explicit contrast with siblings, but the core purpose is unmistakable.

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?

There is no guidance about when to choose this tool over discord_get_channel, or what happens if guild_id is omitted. The appropriate usage is only implied by the verb and resource, not explicitly described.

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