godot_set_project_setting

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

The description adds the useful behavioral detail that changes persist to the project.godot file, which is beyond what the annotations reveal. It also conveys an upsert-like semantics ('Write or update') consistent with the idempotentHint annotation, though it doesn't describe validation or runtime effects.

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, front-loaded sentence with no filler. Every word carries useful meaning, and it is appropriately sized for the tool's simplicity.

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 straightforward config-write operation, the description plus annotations and schema provide enough context to call the tool correctly. The output schema is present, so return value details are covered. The main omission is usage differentiation, but that doesn't block a correct invocation.

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 description itself adds no parameter-level detail, but the nested schema documents name format, allowed value types, and response_format. Since the schema covers the semantics well, the baseline of 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 uses a specific verb ('Write or update') and a clear resource ('a configuration setting in project.godot'), making the tool's function immediately identifiable. It implicitly contrasts with the sibling godot_get_project_settings, though it doesn't name that sibling explicitly.

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 gives no guidance about when to use this tool versus alternatives. It doesn't mention that reading settings should go through godot_get_project_settings, nor does it explain any prerequisites or exclusions.

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