CreateZones

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

Annotations already declare destructiveHint=true, readOnlyHint=false and openWorldHint=false, so the safety profile is covered by structured data. The description adds nothing beyond that: it never says zones are persisted to the model, whether the operation is undoable (archicad_undo exists as a sibling), or how batch failure is handled.

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 short sentences with the action front-loaded and no wasted explanation. The parenthetical category tag is mild noise but the core statement is tight.

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 batch creation tool with a deep nested schema the definition is thin: it never mentions the manual-vs-automatic geometry choice or what the call returns (no output schema exists, and created zone identifiers are what an agent typically needs next). The rich schema and annotations carry most of the load, leaving this merely adequate.

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 100% and every nested field (geometry modes, stampPosition, favoriteName override semantics) is already documented inline, so the baseline of 3 applies. The description adds no syntax or format meaning beyond what the schema provides.

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 ("Creates Zone elements"), which cleanly separates it from CreateWalls, CreateSlabs, CreateColumns and archicad_create_room. The trailing clause "based on the given parameters" is filler and the parenthetical "(Tapir, Element Commands)" adds no distinguishing information.

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 when-to-use guidance, no prerequisites (e.g. active project/story), and no pointer to alternatives such as CreateWalls or archicad_create_room. Nothing tells the agent when this tool is the right choice over a sibling creation command.

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