setup_xreal_project

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

Annotations already indicate readOnlyHint=false, so the description's job is to add behavioral context. It does so by listing the configuration steps (Android build target, XR Plugin Management, NRSDK import). However, it does not mention whether the tool overwrites existing settings or is idempotent, but this is acceptable for a setup tool.

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?

The description is two sentences with no wasted words. The key action and usage are front-loaded. Every sentence adds necessary context.

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?

Given the tool has 8 optional parameters and no output schema, the description explains the overall purpose and steps. It could benefit from mentioning the result (e.g., modifies the current project), but it is still reasonably complete for a setup 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?

Schema coverage is 100% with each parameter having a description, so baseline is 3. The description does not add parameter-specific semantics beyond the schema; it names the high-level steps but does not map them to the individual parameters. No extra value beyond the schema is provided.

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 uses a specific verb ('Sets up'), identifies the resource ('Unity project for XREAL One Pro development'), and lists key actions (configure Android build, XR Plugin Management, import NRSDK). It distinguishes itself from siblings like import_nrsdk by being a broader setup tool and explicitly stating it's the first step.

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 description explicitly states 'This is the first step for any new XREAL mixed reality project,' which tells the agent when to use it. It does not list when not to use or name alternatives, but the context is clear enough given the sibling tools.

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