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

No annotations are provided, so the description carries the entire behavioral burden, and it discloses nothing: not whether the call is read-only, what it returns, whether mode changes session state, or what auth/setup it requires. The only behavioral hint lives in the schema's enum, not the description.

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?

It is short, but this is under-specification rather than conciseness — the single fragment merely echoes the name and conveys no actionable content to front-load.

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 a mode enum, no annotations, no output schema, and a dense sibling cluster, the description provides none of the context an agent needs to invoke it correctly or to prefer it over room.bootstrap or room.lifecycle.plan.

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% for the single 'mode' parameter (enum: create/join/both). The description does not explain what these modes select, what the default is when omitted, or how the choice affects the explanation, so it fails to compensate for the coverage gap.

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 is essentially the tool name restated with a parenthetical ('flow-explainer'). It hints at explaining a room flow but gives no verb+resource statement of what the tool actually produces, and it does nothing to distinguish itself from siblings such as room.bootstrap or room.lifecycle.plan.

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 when-to-use guidance, no prerequisites, no mention of when NOT to use it, and no routing among the many room-related siblings (room.bootstrap, room.lifecycle.plan, integration.plan). An agent has nothing to select on beyond the name.

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