displaybuddy_set

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

No annotations are provided, and the description does not disclose key behavioral traits such as whether setting a property is absolute or incremental, what happens when omitting a property, whether changes are reversible, or any permissions or side effects. A mutation tool should include such details for safe invocation.

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?

The description consists of two concise sentences that immediately convey the tool's purpose and key targeting options. It is front-loaded and contains no redundant or extraneous content.

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?

For a setter tool with 8 optional parameters and no output schema, the description covers basic usage but lacks information about return values, error handling, or default behavior when multiple properties are omitted. It is minimally adequate but could benefit from more operational context.

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 100%, so the schema already documents each parameter's meaning. The description adds context about targeting ('specific display' vs 'all') but does not explain the interplay when both 'display' and 'all' are provided, nor does it provide additional meaning beyond the schema definitions.

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's function: setting display properties like brightness, contrast, volume, input source, or rotation. It distinguishes from siblings like displaybuddy_get or displaybuddy_preset_activate by indicating it modifies properties rather than retrieving or managing presets.

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 explains when to target a specific display by name or all displays at once, providing clear guidance on using the 'display' vs 'all' parameters. However, it does not explicitly state when not to use this tool or mention alternative tools for non-modification tasks, though these are implied by sibling names.

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