ue_project_set_plugins

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

No annotations are provided, so the description carries the burden. It discloses that the tool modifies the .uproject file and that the editor must be restarted if open. This is useful but does not detail persistence behavior or error handling.

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 and front-loaded with the core action. It uses efficient language to convey the main purpose and a key side effect. No unnecessary words.

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 main effect (modifying .uproject) and a key behavior (restart requirement). However, it lacks details about return values, error states, and the exact format of parameters. For a mutation tool with no output schema, this is adequate but not fully complete.

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 description coverage is 0%, and the description does not explain the parameters 'enable', 'disable', or 'uproject'. It only implies that plugins are enabled/disabled, but does not specify that parameters are arrays of plugin names or what the uproject parameter expects. This forces the agent to infer meaning from the tool name and context.

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 enables/disables plugins by writing to the .uproject file, which is a specific verb+resource. It also notes it's useful for existing projects, providing context. However, it does not explicitly differentiate from sibling tools like ue_set_project_setting.

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 mentions that to use the bridge, PythonScriptPlugin and RemoteControl must be enabled, giving a specific use case. It also advises restarting the editor if already open. But it lacks explicit guidance on when to use this tool versus alternatives or prerequisites beyond the bridge scenario.

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