set_button_style

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

With no annotations provided, the description carries full burden. It correctly discloses that only provided values are changed, implying no side effects on unspecified properties. This is sufficient for a simple style update tool, though permissions or destructive nature 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?

Single sentence, no wasted words. The purpose is front-loaded, and the critical behavior that only provided values are changed is immediately stated.

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 existence of an output schema (not shown), the description does not need to explain return values. However, with 7 parameters and zero schema descriptions, the tool needs more parameter guidance. The description is adequate for a simple update but lacks completeness in documenting all param behaviors.

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 coverage is 0%, yet the description adds no parameter-specific details. It does not explain format of 'color', 'bgcolor', 'size', etc. The agent must rely on parameter names alone, which may be ambiguous (e.g., 'bgcolor' vs 'color'). The description 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 clearly states the tool sets multiple button style properties at once, distinguishing it from single-property siblings like set_button_color and set_button_text. The verb 'Set' and resource 'button style properties' are specific.

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?

The description says 'All parameters optional — only provided values are changed,' which helps the agent understand when to use it (batch update) and that it is non-destructive. However, it doesn't explicitly mention when not to use it or alternatives like set_button_style_verified.

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