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

No annotations are provided, so the description carries the full burden of behavioral disclosure. The single phrase 'create room' gives no information about state changes, persistence, permissions, idempotency, or side effects—so an agent cannot predict what calling the tool actually does beyond a vague create action.

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 definition is short, but that brevity reflects under-specification rather than efficient, purposeful writing. A useful one-line description would include the tool's object and action details; this one merely lists a verb and a noun.

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 tool with two required parameters and no output schema or annotations, the description is completely inadequate. The agent cannot know what the tool returns, what a room is, or what makes a valid call beyond the schema constraints.

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 names neither 'name' nor 'description' parameters. It adds no meaning beyond the raw JSON schema, leaving the agent to guess semantics such as whether the name must be unique or how description is used.

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 'create room' merely restates the tool name, providing no verb-resource detail beyond the name itself. It does not explain what a room is or what creating one entails, and it does not differentiate the tool from siblings like create_task or post_message.

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 on when to use this tool versus alternatives, no prerequisites, and no hint of when it would be inappropriate. The description offers no context for choosing create_room over any related tool.

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