get_baro_i2c_address

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

No annotations are provided, so the description must carry full behavioral disclosure. It states this is a read operation (get) but does not describe side effects, authorization needs, or behavior when the prerequisite is unmet. Minimal transparency beyond the basic read nature.

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—one line containing the key information: purpose, type, default, and requirement. No superfluous words, front-loaded and efficient.

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 no-parameter getter with no output schema, the description covers the key aspects: what the value represents, its default, and a prerequisite. It could optionally explain valid address range or interaction with the barometer driver, but it is sufficiently complete for its simplicity.

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 schema coverage is 100%. The description adds value by specifying the type (UINT8) and default value (0) for the underlying setting, which is not captured in the schema. Baseline 4 for zero parameters is appropriate.

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?

Clearly states it gets the I2C address override for the barometer, with default 0 meaning auto-detect. The verb 'get' aligns with the name. Briefly distinguishes from the corresponding setter tool implicitly but not explicitly among siblings.

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?

Mentions a prerequisite (Requires: USE_BARO) but provides no guidance on when to use this tool versus alternatives like other get_* tools. No context on typical scenarios or exclusions.

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