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

No annotations are provided, so the description must fully disclose behavioral traits. It mentions configuration and verification but does not clarify whether the tool is read-only or modifies files, what happens on failure (e.g., missing SDK), or any side effects like setting environment variables. This lack of transparency leaves the agent uncertain about the tool's safety and outcomes.

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 short, well-structured with clear sections for purpose and parameter details. Every sentence adds value, and the parameter list is formatted cleanly. There is no redundant information.

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 tool has two parameters and an output schema (not shown). The description lacks details about return values or side effects, which are important for a setup tool. However, given the simplicity and the presence of an output schema, the description is minimally adequate but could be enhanced with more context on outcomes.

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 0%, so the description must compensate. It fully explains both parameters: project_path (path or env var fallback) and verify_sdk (boolean with default). This adds significant meaning beyond the schema structure, enabling correct usage.

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 configures Unity project path and verifies VRChat SDK installation, detailing specific checks (VRCSDK3-AVATAR, assemblies, structure). This is a specific verb+resource combination that distinguishes it from sibling tools like unity_build_avatar or unity_import_fbx.

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 initial project setup or verification before other VRChat operations, but does not explicitly state when to use or exclude, or mention alternative tools. Usage context is clear but lacks guidelines on prerequisites or scenarios where this tool is inappropriate.

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