get_guild_info

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

No annotations are present, and the description does not mention side effects, permissions, or whether the operation is read-only. It provides no behavioral details beyond the basic function.

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 concise and to the point, with no unnecessary fluff. However, it could be slightly more detailed without becoming verbose, hence a 4 instead of 5.

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?

The description lacks essential context: it does not mention what happens when guild_id is null, the exact return format, or any error conditions. It provides only a high-level summary, which is insufficient for complete usage.

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?

The only parameter, guild_id, has no description in the schema and the tool description does not explain its purpose, format, or optionality. The description mentions 'about a Discord server' but never links it to the parameter, leaving semantics ambiguous.

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 tool's function: 'Get detailed information about a Discord server' and lists example data fields. This distinguishes it from sibling tools like list_guilds, which likely return summaries.

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 does not specify when to use this tool versus alternatives (e.g., list_guilds) or whether the guild_id parameter is required or optional. It lacks context on invocation scenarios or prerequisites.

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