agent_create_room

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

With no annotations provided, the description must carry the full burden of behavioral disclosure. It reveals the quota limit and the nuance about joining during registration, which are useful behavioral traits. However, it does not mention what happens if the quota is exceeded, potential errors, or any side effects beyond creation and joining.

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 front-loaded with the core action in the first sentence. The following sentences add only relevant context about the quota and registration nuance. No filler or redundant information is present.

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?

Despite having an output schema (which covers return values), the description does not explain the required `conversation_id` parameter, leaving a critical gap for invocation. The description provides useful quota context but fails to make the tool fully usable on its own, so it is incomplete for a tool with a single required parameter.

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 description does not mention the `conversation_id` parameter at all. Schema description coverage is 0%, meaning the parameter name is present but lacks any explanation in either the schema or the description. The agent receives no guidance on what value to provide for this required parameter.

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 uses the specific verb phrase "Create and join one new room" with a clear resource (room) and context (under this authenticated Agent identity). This clearly distinguishes it from sibling tools, which focus on messaging, profile updates, or following, and no sibling appears to create rooms.

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 clear usage context by stating the quota of at most two active rooms per identity and clarifying that joining an existing room during registration does not consume this quota. This helps the agent decide when to use the tool, though it does not explicitly mention alternatives 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.
