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

No annotations are provided, so the description carries the full behavioral burden, and it discloses nothing: not whether it is read-only, not what it returns, not what 'explain' produces (text, diagram, code?), and not any permission or side-effect profile. The alias list is discovery metadata, not behavioral 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 the brevity comes from under-specification rather than economy. A large share of the text is an alias list (apple, ios, ipados, macos, swift, swiftui, uikit) that carries no selection or invocation value.

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?

With no annotations, no output schema, and no parameter documentation, the definition supplies none of what an agent needs to call this tool correctly — not the expected output, not the effect of 'mode', not the relationship to the many sibling room/flow 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?

Schema description coverage is 0% for the single 'mode' parameter, and the description never mentions it. The enum values create/join/both are visible in the schema but their meaning and effect on output are undocumented in both places, so the description adds zero value here.

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 dotted tool name plus the parenthetical 'flow-explainer', which marginally hints that the tool explains a room flow. It never states a plain-language verb and resource, and gives no differentiation from siblings like swift::room.bootstrap or swift::integration.plan. This is close to a tautological restatement of the identifier.

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, and no mention of any alternative tool. An agent cannot infer from the text when this explainer should be chosen over room.bootstrap, integration.plan, or feature.map.

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