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

With no annotations, the description relies solely on 'List' to convey behavior, which implies a read-only operation. However, it does not disclose potential network calls, authentication needs, or error conditions. It is minimally sufficient but lacks depth beyond the verb.

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, information-dense sentence with no fluff or repetition. Every word adds value, making it perfectly concise.

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?

While the description fully answers 'what' and 'what kind', it is slightly terse. For a simple listing tool, it's mostly complete, but could have mentioned if any authentication is implied or if results are real-time. Still, the basic context is adequate.

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 tool has zero parameters, and the baseline for such cases is 4 per the rubric. The description does not need to explain parameters since none exist, and it doesn't add unnecessary complexity.

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 lists 'joinable open rooms and live in-progress games' on fluxdots.com, using the specific verb 'List' and distinct resources. This differentiates it from siblings like flux_host or flux_join, which imply different operations.

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?

While the description is clear, it provides no guidance on when to use this tool versus siblings or any exclusions. There is no mention of alternatives or preconditions, leaving the agent without explicit direction for when to select this tool over others.

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