get_angle_earth_ref

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

No annotations are provided, so the description fully carries the burden. It discloses the value range, units (UINT8, 0–100), default (100), and the behavior (returns the current proportion). This covers the essential behavioral traits for a simple read operation.

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 with additional details in brackets. It is front-loaded with the purpose and provides all necessary information without any fluff. Every word earns its place.

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?

Given the tool has no parameters and no output schema, the description is quite complete. It covers the purpose, range, default, and a usage recommendation. It could be slightly more explicit about the return value format, but it is implied.

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, so the baseline is 4. The description does not need to add parameter semantics, as there are none. It correctly describes the return value.

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 proportion of earth-frame reference used in angle mode. It defines the range (0-100) and explains the meaning of the endpoints (0=body frame, 100=full earth frame). This is specific and distinguishes it from other get tools in the sibling list.

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 recommendation ('100 is recommended for GPS rescue compatibility'), which guides the user on choosing the appropriate value contextually. However, it does not explicitly state when to use this get tool versus other tools (e.g., set_angle_earth_ref), though that is implicitly clear.

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