update_device

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

With no annotations provided, the description must disclose behavioral traits but only states that settings are updated. It does not mention whether the update is partial or full, any required permissions, side effects, or what happens to existing settings not in the payload. For a mutation tool, this is a significant gap.

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 front-loads the action and resource, with a parenthetical listing of key fields. It is concise, efficient, and contains no redundant 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 simple update tool with four schematically defined parameters, the description is adequate but not complete. It provides the core purpose and fields, yet lacks behavioral context (e.g., partial update semantics, prerequisites, or response format) that would be especially important given the absence of annotations and an output schema.

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%, so the schema already documents each parameter's meaning. The description adds minimal value by listing the fields in parentheses, but it does not provide any additional semantic detail beyond what is in the schema.

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 action ('Update') and the resource ('a DAKboard device's settings'), and explicitly lists the specific settings involved (name, IP address, assigned screen). This distinguishes it from sibling tools like update_screen and update_block, which target different resources.

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 context is clear: use this tool to update device settings. Though it does not explicitly name alternatives or exclusions, the scope is unambiguous given the resource focus and sibling names, providing adequate guidance without needing to spell out when not to use it.

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