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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so safety is covered. The description adds genuinely useful context the annotations do not: the payload is a static ~24 KB script and it takes no arguments. It stops short of 5 by not saying anything about the return format or how the script should be consumed.

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?

Two sentences, zero padding, with the identity and content of the returned script front-loaded. 'Takes no arguments' mildly duplicates the empty schema, a small redundancy that keeps it from a 5.

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 output schema, the description carries the burden of describing the return value and does so adequately: an ordered question list with allowed answers, required flags, and conditional applicability, plus a size hint. Format details (JSON structure, how to interpret conditionals) are the only notable omission for an otherwise simple, argument-free reader.

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?

Zero parameters, so the baseline is 4. The description confirms 'Takes no arguments', which is consistent with the empty schema and prevents an agent from hunting for optional inputs, but adds no further semantics.

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?

States a specific verb and resource: it returns BuildBatch's full ordered question script for a room plan, and even enumerates what the script contains (questions, allowed answers, required flags, applicability conditions). That is far more than a restatement of the name. It does not explicitly contrast itself with siblings like quick_room_list or plan_room, so it stops short of a 5.

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 phrase 'for a detailed room plan' implies the context in which this script is needed, which faintly distinguishes it from the lightweight quick_room_list sibling, but there is no explicit when-to-use, when-not-to-use, or named alternative. Usage must be inferred.

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