game_ui_theme

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

No annotations are provided, so the description must disclose behavioral traits. However, it only states 'Apply theme overrides' without explaining if overrides are permanent, cumulative, or affect child nodes. Side effects or required permissions 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?

A single sentence of 6 words immediately conveys the tool's action and target. Every word is necessary; no redundancy or extra information. It is front-loaded and efficient.

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 lack of output schema and annotations, and the presence of a nested object parameter, the description is too brief. It does not explain how overrides merge with existing themes, what the valid keys/values are, or what the outcome looks like. More context is needed for safe and correct usage.

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 100%, so both parameters have descriptions. The description adds no extra meaning beyond the schema. For high-coverage cases, this is the baseline. However, the nested 'overrides' object lacks details on keys or values, which would help agents construct valid input.

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 'Apply theme overrides to a Control node' clearly states the action (Apply) and the resource (theme overrides to a Control node). It distinguishes itself from sibling tools like 'manage_theme_resource' which is about managing theme resources globally, and other game_ui_* tools that handle different UI aspects.

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?

No explicit guidance on when to use this tool versus alternatives. Usage is implied by the name and description, but there is no mention of prerequisites, when not to use, or alternative tools. This leaves an agent without clear decision boundaries.

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