game_process_mode

Set a Godot node’s process mode to choose when it runs during pause, always, or not at all. Use it to control pause behavior and keep specific nodes active.

Instructions

Set node process mode (pausable/always/disabled)

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

C2.9/5.0
Behavior2/5

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

With no annotations provided, the description bears the full burden of disclosing side effects, but it does not explain what pausable, always, disabled, inherit, or when_paused actually do at runtime. It also doesn't mention whether this affects the node's children, whether it changes pause state, or what the consequences of 'disabled' are.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, front-loaded sentence with no wasted words. It is appropriately short for a simple setter-like operation, though it sacrifices some behavioral detail for terseness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a two-parameter tool with complete schema coverage, the description is minimally adequate: an agent knows the operation and can find the parameters in the schema. But since there are no annotations and no output schema, the lack of mode semantics and side effects leaves a moderate gap for a state-changing operation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the schema already documents both parameters. The description adds a partial list of mode values, but it omits 'inherit' and 'when_paused', and it does not clarify their meanings beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('Set') and identifies the target resource ('node process mode'), which is distinct from global pause or time-scale tools among the siblings. However, it lists only three of the five valid modes and does not explicitly differentiate from sibling tools like game_pause.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is given about when to use this tool versus alternatives such as game_pause or game_time_scale. The description simply states the operation without any context for selecting it.

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