validate_xreal_setup

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

Annotations declare readOnlyHint=true, and the description confirms read-only behavior by stating 'validates' and 'reports issues'. No contradictions. Description adds context about what is checked beyond annotations.

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: first states overall purpose, second enumerates checks. No redundant information. Each sentence earns its place.

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?

The description covers the tool's function but does not specify the output format or what 'reports issues' means (e.g., list of strings, success/failure). Given no output schema, the description could be more explicit about return value structure.

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 all parameters described. The description lists checks but does not add new information beyond the schema's parameter descriptions. Baseline 3 is appropriate since schema already provides full 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?

The description clearly states the tool validates Unity project configuration for XREAL development and lists specific checks (NRSDK, Android settings, XR Plugin Management, permissions). It distinguishes from sibling tools like setup_xreal_project or build_xreal_apk.

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 implies usage for checking configuration before development or deployment, but does not explicitly mention when not to use or alternative tools. However, the purpose is clear enough for an agent to infer appropriate use.

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