Create Scalable Display bus

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

Annotations already indicate non-read-only, non-destructive, and open-world behavior. The description adds context about the scaffold's contents (tile maps, status, calibration notes) but does not disclose potential side effects like overwriting existing nodes or relying on a config file. This is adequate but not rich.

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, front-loaded sentence with no redundant words. Every word adds value, and it avoids repeating schema or annotation 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?

For a tool that creates a complex scaffold with 7 parameters and no output schema, the description is too terse. It does not explain the config_file's role, the structure of the scaffold, or what the agent can expect as a result. Given the low schema coverage, more context is needed.

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 43%, and the description does nothing to explain the undocumented parameters (active, canvas_width, canvas_height, display_count). It loosely relates 'display tile maps' to display_count/canvas dimensions but 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 states a specific verb ('Create') and resource ('Scalable Display TOP scaffold'), and lists key components (display tile maps, status, calibration setup notes). This clearly distinguishes it from sibling tools like create_blacktrax_tracking_bus, though it could be more explicit about what the 'bus' entails.

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?

There is no guidance on when to use this tool versus the many similar create_*_bus tools, nor any mention of prerequisites or alternatives. The description only states what it does, not when to choose it.

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