set_gps_ublox_acquire_model

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

With no annotations provided, the description carries the full burden but only reveals that the tool sets a UINT8 value with a default. It does not disclose behavioral traits such as whether the change is persistent, requires a reboot, or has immediate side effects, leaving important behavior unclear.

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: a single sentence followed by bracketed extra info. It front-loads the purpose and includes essential details (type, default) without any superfluous words, earning every character.

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 annotations or output schema, the description covers the essential purpose and parameter details. It could be improved by mentioning valid UBlox model values, but given the low complexity, it is fairly 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 description adds meaning beyond the input schema by explaining that the parameter is the 'UBlox dynamic model used while acquiring fix' and noting the default value 'STATIONARY'. The schema merely labels it as 'Value for gps_ublox_acquire_model (UINT8)', so the description provides valuable context beyond the schema itself.

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 sets the UBlox dynamic model used while acquiring fix, distinguishing it from related siblings like set_gps_ublox_flight_model. It specifies the parameter type and default value, leaving no ambiguity about the tool's purpose.

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 does not provide any guidance on when to use this tool versus alternatives (e.g., set_gps_ublox_flight_model) or any prerequisites. It only states what the tool does, leaving the agent to infer usage context without explicit when-to-use or when-not-to-use information.

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