Export room data including names, numbers, levels, areas, perimeters, and departments from the Revit model for analysis and reporting.

Instructions

Export data for all rooms defined in the Revit model.

Returns room names, numbers, levels, areas, perimeters, and departments in a structured format suitable for analysis and reporting.

Args: ctx: MCP context for logging

Behavior4/5

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 exports all rooms and returns a structured format, implying a read-only operation. However, it lacks details on potential side effects, permission requirements, or failure modes.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise with two sentences and an args note, front-loading the purpose. Every sentence earns its place without unnecessary fluff.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no parameters, no output schema, and no annotations, the description provides adequate context: it names the exported data fields and indicates the output is structured. It could mention output format or limits, but overall it is sufficient for a simple data export tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has no parameters, and the schema coverage is 100%. The description does not add parameter information, but the baseline for zero parameters is 4, as there is nothing to clarify.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool exports data for all rooms in the Revit model, listing specific return fields (names, numbers, levels, etc.), which distinguishes it from sibling tools like export_document or export_ifc.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies use for room data reporting but does not explicitly state when to use this tool versus alternatives, nor does it mention exclusions or prerequisites.

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