game_canvas

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

Description says 'Create/configure' but doesn't disclose side effects, whether existing objects are modified or replaced, or any prerequisites. Annotations are minimal and don't compensate.

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?

Description is short and to the point, but could include more detail without adding fluff. No wasted sentences.

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?

Tool manages canvas layers and modulate, which are complex concepts in Godot. The description lacks explanation of how they relate, default behavior, or return values. Incomplete for a 6-parameter tool with no output schema.

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 baseline is 3. The description adds no extra meaning beyond what the schema already provides for parameters.

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?

Description clearly states the tool creates/configure CanvasLayer and CanvasModulate, which are specific resources in Godot. It distinguishes from siblings by focusing on canvas-related objects.

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 guidance on when to use this tool versus alternatives like game_canvas_draw or other canvas-related tools. Missing context for when to create vs configure.

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