Project Init

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

No annotations are provided, so the description carries the full burden of disclosure. It only states the creation action without detailing side effects, what happens to existing files, or the content of the manifest. Key behaviors like overwriting (the 'force' parameter) are not mentioned.

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 a single, efficient sentence with zero wasted words. It is front-loaded and to the point.

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 4 parameters and no output schema, the description does not explain the impact of options like enableBlender or enableLuau, nor what the manifest contains. A user cannot infer the full scope of the action.

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 good individual parameter descriptions. The tool's description adds no extra meaning beyond 'create manifest', so baseline 3 is appropriate.

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 'Create the local Roblox all-in-one MCP project manifest in the current workspace.' It uses a specific verb ('Create') and a specific resource ('project manifest'), and uniquely distinguishes this tool from siblings which are all Blender/Roblox/Unity/Unreal specific actions.

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 this is used for project initialization, but does not explicitly state when to use it versus alternatives, nor does it provide any do's/don'ts or prerequisites.

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