displaybuddy_sync

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

No annotations are provided, so the description carries full burden. It explains the basic function but fails to disclose behavioral traits such as potential side effects (e.g., temporary display flickering when enabling/disabling sync), required permissions, or whether changes are persistent. Status action could be read-only but is not highlighted as such.

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 is concise with three sentences: one explaining the sync concept, one listing actions. No redundant information, every sentence adds value.

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 (2 params, no output schema, no annotations), the description covers the core functionality. However, it lacks information about return values (e.g., what status returns) and error handling (e.g., invalid display name). Adequate but not fully complete.

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%, with both parameters described in the input schema. The description adds context about sync's effect but does not provide additional parameter-specific details beyond what is in the schema. Baseline of 3 is appropriate.

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 manages display sync and explains the concept: all displays follow one source display's brightness, contrast, and volume. It lists three distinct actions (status, enable, disable), making the purpose specific and distinguishable from sibling tools like displaybuddy_set or displaybuddy_get.

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 implies usage for sync management but does not explicitly state when to use this tool over alternatives (e.g., when to use displaybuddy_set vs sync). No when-not-to-use scenarios or prerequisites are provided, leaving some ambiguity for the AI agent.

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