set_gps_auto_config

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

No annotations are provided, so the description bears full responsibility for disclosing behavior. It mentions the default value and the purpose but does not explain the effects of setting it to OFF, valid input values beyond the default, or any side-effects. This leaves significant gaps in transparency for a mutation tool.

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 brief (two sentences plus a bracketed note) and front-loads the purpose. It efficiently conveys the core function and a usage tip without 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 setter with one parameter and no output schema, the description covers the main purpose and gives a usage condition. However, it fails to specify valid or expected values (e.g., 0/1 or ON/OFF), and the type mismatch undermines completeness. It meets the minimum threshold but has clear gaps.

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 describes one parameter with 100% coverage. The description adds a default value ('ON') and a type hint ('UINT8'), which clarifies the expected input. However, there is a contradiction: the schema says type 'string' while the description says 'UINT8', causing potential confusion about the actual value format (e.g., numeric '1' or string 'ON').

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 sets 'gps_auto_config' for automatic UBlox module configuration, listing specific configurable aspects (baud rate, update rate, message types). It avoids tautology and uses a specific verb-resource pair, though it doesn't explicitly differentiate from sibling set_* tools.

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?

Provides a usage condition 'Leave ON unless you pre-configure the module with uCenter,' giving some guidance on when to disable. However, it lacks explicit alternatives or a clear when-not-to-use statement, and does not reference other tools in the sibling list.

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