setup_navigation_region

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

No annotations provided, so description carries full burden. It only states 'Add' without disclosing behavior like overwriting existing regions, required permissions, or effects on scene. Minimal transparency beyond action.

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?

Single sentence, no wasted words. However, it could front-load key aspects like dimension and parent path handling. Still concise and readable.

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?

Tool has 5 parameters including nested properties object, multiple region types, and optional parent. Description fails to mention that dimension parameter controls which type is created, or that properties can set navigation_mesh and enabled states. Incomplete guidance for complex tool.

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?

All 5 parameters have descriptions in schema (100% coverage), so description adds only the phrase 'with optional configuration' which loosely covers properties parameter. No additional semantic value beyond schema.

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?

Description uses 'Add' verb and specifies resource type (NavigationRegion2D/3D) with optional config, clearly distinguishing from sibling tools like setup_navigation_agent or remove_navigation_region. However, it could be more explicit about the tool's focus on region creation.

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 on when to use this tool vs alternatives like setup_navigation_agent or directly setting up regions. Sibling tools include both creation and removal of navigation regions, but description provides no context for selection.

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