unity_setup_gesture_layer

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

Description explains what the tool does but does not disclose behavioral traits such as whether it overwrites existing layers, requires specific Unity project setup, or any side effects. No annotations provided to 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 concise: one sentence for purpose, one for gesture list, and bullet-pointed parameters. No wasted words; front-loaded with key information.

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 simplicity, the description covers the main function and parameters. However, it lacks details on return value (output schema exists but not mentioned) and behavior on existing files. Adequate but not thorough.

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?

Description adds meaning beyond the input schema by explaining each parameter: project_path, output_path, and hand_gestures with allowed values ('default' vs 'custom'). Since schema has no descriptions, this is valuable context.

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 it creates a VRChat Gesture FX layer with hand gesture states and lists the 8 standard gestures. However, it does not differentiate from the sibling tool 'vrc_setup_gestures', which may have overlapping functionality.

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 vs alternatives (e.g., vrc_setup_gestures). It does not provide exclusions or prerequisites, leaving the agent to infer usage context.

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