Get Discord channel

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

Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true and openWorldHint=true, so the safety profile is fully covered. The description adds nothing beyond that—no note about live API calls to Discord, permission requirements to view the channel, or behavior when the channel is missing or inaccessible.

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 single sentence is front-loaded and free of padding, which is good, but its brevity comes at the cost of any substantive information—it is under-specification framed as conciseness.

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?

An output schema exists, so return values need not be explained, but for a tool with two required, undescribed ID parameters and no usage guidance, the description leaves the agent without enough to invoke it confidently or recover from a wrong-ID error.

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 both required parameters (guildId, channelId) are documented only by regex patterns. The description does not explain that these are Discord snowflake IDs, nor clarify the parent guild vs. target channel relationship, so it fails to compensate for the coverage gap.

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?

States a specific verb+resource: fetching metadata for a single Discord channel, which distinguishes it from the many list_* siblings. However, it never explicitly contrasts with discord_list_channels or discord_get_guild, so the agent must infer the singular-vs-list distinction.

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 when-to-use guidance, no prerequisites, and no mention of alternatives such as discord_list_channels when the channel ID is unknown. The agent is left to infer that this tool requires a known channelId and is not a discovery mechanism.

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