Create monitor layout panel

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

Annotations already indicate readOnlyHint=false and destructiveHint=false, so the agent knows this is a non-destructive write operation. The description adds that it creates a scaffold with specific parts, which gives some context about what actions it performs, though it doesn't disclose details about side effects, permissions, or network modifications.

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 a single sentence that is front-loaded with the primary action ('Create a Monitors DAT inventory scaffold') and then lists the included components. Every word adds value, with no redundancy or filler.

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?

The tool has 5 parameters, no output schema, and only a 40% schema description coverage. The description leaves significant gaps: it doesn't explain what a 'Monitors DAT inventory scaffold' is, what 'preflight checks' entail, or how parameters influence the result. The agent would likely be uncertain about expected behavior and output.

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 only 40%; the description does mention 'monitor maps' and 'GPU maps' which loosely relate to monitor_count and gpu_count, but it doesn't explain parameter semantics such as what include_direct_display_hint does or how parent_path is used. The description fails to compensate for the low schema coverage.

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 purpose: 'Create a Monitors DAT inventory scaffold' and lists specific components (monitor maps, GPU maps, preflight checks, setup notes). This specific verb+resource combination distinguishes it from sibling tools like create_control_panel or inspect_gpu_and_displays, which focus on different aspects.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites, contexts (e.g., when setting up multi-monitor systems), or scenarios where other tools would be more appropriate. No exclusions or alternative tool names are given.

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