godot_create_theme

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

The tool is a write operation (annotations: readOnlyHint=false) and saves a file via save_path, but the description does not disclose that it writes to disk, whether existing files are overwritten, or that it can optionally assign the theme to a node. Without annotations covering these behaviors, the description carries the burden but does not address them.

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 concise sentence that immediately conveys the core action. It is efficient, though it could be slightly expanded to add context without becoming verbose.

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's complexity (nested StyleBoxFlatConfig, many optional parameters, required save_path, optional apply_to_node_path), the description is severely lacking. It does not explain how to structure the overrides, what save_path is for, or how the parameters relate, leaving the agent ill-equipped to call the tool correctly.

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% according to context, and the description only vaguely mentions color, font, and stylebox without explaining the structured nature of the parameters (e.g., type-grouped objects, StyleBoxFlatConfig details, the requirement of save_path). It fails to compensate for the lack of schema descriptions.

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 states a specific verb ('Create') and resource ('Theme resource') and lists the overrides it supports (color, font, stylebox). However, it does not differentiate from nearby siblings like godot_apply_theme_override or godot_create_material, so it is clear but not uniquely distinguishing.

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?

There is no guidance on when to use this tool versus alternatives. It does not mention that it creates a new resource file, when to use it over applying overrides to an existing node, or any prerequisites such as an open scene. The agent is left to infer usage from the tool name.

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