create-room-as-host

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

With no annotations provided, the description carries the full burden. It discloses that the tool creates a room, sets a host message, returns an invite code, and requires a follow-up call to 'wait-for-room-response'. However, it lacks details on permissions, rate limits, error handling, or what happens if the room creation fails, leaving behavioral gaps.

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 front-loaded with the main action but includes verbose instructions like 'must be clearly given to the user so they can copy it', which could be more concise. Some sentences (e.g., about user direction) are redundant with parameter context, reducing efficiency.

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?

Given no annotations, no output schema, and a single parameter with full schema coverage, the description is moderately complete. It covers the tool's purpose, usage flow, and output (invite code), but lacks details on return values, error cases, or integration with sibling tools beyond 'wait-for-room-response'.

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 100%, so the schema already documents the single parameter 'hostFirstMessage' with its description. The description adds context by explaining that this message is 'the first message that will be sent as the host' and is based on 'user directive', but doesn't provide additional syntax or format details beyond the schema.

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 action ('create a room, and be the host') and resource ('room'), distinguishing it from siblings like 'join-with-invite' or 'exit-room'. However, it doesn't specify what type of room (e.g., chat, meeting) or platform, making it slightly less specific than a perfect score.

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 explicit guidance on when to use this tool: 'after calling this, please immediately call the wait-for-room-response tool'. It also implies usage context by mentioning 'The user should provide clear direction for the objective of the room', though it doesn't explicitly name alternatives like 'join-with-invite'.

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