Generate UID

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

The readOnlyHint annotation already indicates no mutation, and the description adds that the result is a unique ID string. However, it does not disclose details such as whether the ID is random, persistent, or scoped to the project; this is a minor gap given the simple, read-only nature.

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 very short and front-loaded, with each sentence carrying necessary information. The return type statement is useful and directly explains output, so there is no filler or wasted content.

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?

For a zero-parameter tool with a read-only hint and an output schema, the description is sufficient. It states the action and the return value clearly, and there are no complex inputs, side effects, or usage conditions that need extra explanation.

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?

The tool accepts zero parameters, so there is no parameter burden to clarify. The description and schema are fully aligned, and the baseline of 4 for parameter-less tools 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 the action: generating a unique ID for Godot resources, and specifies the return as a unique ID string. The verb 'Generate' plus the resource type makes the tool's purpose unambiguous, even without sibling differentiation.

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 when a Godot resource UID is needed, but it does not explicitly state when to use this tool versus alternatives or mention exclusions. Since there are no obvious sibling tools doing the same thing, this is acceptable but still relies on inference.

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