create_device_tier_config

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

With no annotations, the description carries the full burden of behavioral transparency. It only discloses that the tool is disabled in read-only mode, but does not explain side effects, required permissions, potential irreversibility, or any other behavioral nuances. The bare statement 'Create a new device tier config' is descriptive but lacks depth.

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 exceptionally concise, containing only the essential purpose and a critical operational constraint. It avoids unnecessary fluff and is structured in a clear, direct manner.

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 creation tool with no annotations and a three-parameter schema, the description is sparse. It omits any information about prerequisites, effects on existing configs, or typical usage scenarios. The read-only mode note is helpful but insufficient for full context. The description relies heavily on the schema and tool name for understanding.

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?

The description does not elaborate on any parameters. While the input schema provides descriptions for 'config' and 'allow_unknown_devices', the tool description itself adds no parameter guidance. Since schema coverage is 100%, the absence in the description is less critical, but it still doesn't help the agent understand parameter relationships or usage context beyond what the schema already provides.

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 new device tier config.' This is specific and unambiguous, distinguishing it from sibling tools that manage other resources. It directly names the action and resource.

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 a clear usage constraint: 'Disabled in read-only mode.' This tells the agent when the tool cannot be used, which is an explicit exclusion. No alternative tools are mentioned, but there are no direct siblings for creating device tier configs, so this is adequate.

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