get_pwr_on_arm_grace

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

No annotations are provided, so the description carries full burden. It indicates a read operation (Get) and specifies the type (UINT8), range (0–30), and default (5). However, it does not explicitly state that it is a read-only, non-destructive operation, though that is implied. The added context is helpful but not exhaustive.

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, well-structured sentence that includes the parameter name, its purpose, and the value constraints (type, range, default). It is concise and front-loaded, with no unnecessary words.

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 getter with no parameters and no output schema, the description is complete. It conveys what the tool retrieves, why it exists, and the constraints on the returned value. No additional information 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?

The input schema has no parameters, and schema coverage is trivially 100%. The description adds value by providing the range and default value, which are not present in the schema. This extra information helps the agent understand the expected output without needing to refer to other sources.

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 retrieves the 'pwr_on_arm_grace' setting and explains its purpose: it's a grace period after power-on that blocks arming to prevent arming before receiver binds. While it uses a specific verb and resource, it does not explicitly differentiate from the many other 'get_' sibling tools, but the explanation of the parameter's role makes the purpose clear.

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, such as the sibling 'set_pwr_on_arm_grace'. It does not mention that to modify this setting, one should use the corresponding setter, nor does it explain typical scenarios for retrieving the grace period.

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