get_baro_bustype

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 the tool is a read operation ('Get'), which implies no destructive behavior, but it does not explicitly state that it is safe, side-effect-free, or what the return value looks like. The behavioral disclosure is minimal.

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 extremely concise, consisting of a single sentence plus a parenthetical note. It front-loads the purpose and includes essential details (type, default, requirement). Every element serves a purpose with no redundancy.

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 parameterless getter with no output schema, the description provides the purpose, type, default, and a prerequisite. However, it does not list all possible values (e.g., SPI, I2C) beyond the default, and it lacks details about the return format. It is adequate but could be more complete.

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 zero parameters, and schema description coverage is 100%. Per guidelines, with full schema coverage the baseline is 3. The description adds marginal value by noting the default ('default: SPI') and data type ('UINT8'), but since there are no parameters, this is already implied by the schema context.

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 that the tool retrieves the barometer bus type ('Get baro_bustype: Barometer bus type.'). The verb 'Get' indicates a read operation, and the resource is explicitly named. Among many similar 'get_*' tools, this one is distinct in targeting the bus type, making its purpose unambiguous.

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 mentions a prerequisite ('Requires: USE_BARO'), which provides some context, but it does not specify when to use this tool versus alternatives (e.g., 'set_baro_bustype' or other barometer-related getters). There is no guidance on when not to use it or what distinguishes it from siblings.

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