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

No annotations are provided, so the description carries the full burden — and it discloses nothing. It does not say whether the tool is read-only, whether it returns prose vs. code, how large the output is, or whether it requires an existing project context.

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 sentence is a title echo with zero informational payload. There is nothing to front-load because nothing substantive is said.

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 an opaque name, an unexplained enum parameter, no annotations, and no output schema, the description should do all the work — instead it does none. An agent has no basis for choosing this over the many sibling planning/explanation tools.

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?

There is one parameter, 'mode', with a create/join/both enum, and schema description coverage is 0%. The description adds no meaning beyond the raw enum values — it does not explain what 'both' returns or how the modes change the explanation produced.

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 plus a parenthetical alias: 'MediaSFU ReactJS :: room.flow.explain (flow-explainer).' It never states a verb or what is actually explained (room creation flow? join flow? lifecycle sequence?), only that the tool is a 'flow-explainer'. This is tautological naming rather than a purpose statement.

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?

No guidance is given about when to invoke this tool, when not to, or how it relates to alternatives such as the sibling room.bootstrap, room.lifecycle.plan, or integration.plan. At best the name weakly implies 'use this to understand room flows,' which is inference, not instruction.

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