set_simplified_pids_mode

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

With no annotations provided, the description must disclose all behavioral traits. It mentions the data type (UINT8) and default value (RPY), but omits critical details such as whether the setting persists across reboots, requires a restart, or has any side effects. This is insufficient for a write 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 extremely concise: two sentences that immediately state the action and provide essential context. Every word adds value, with the example and default packaged efficiently.

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 tool, the description covers the core purpose and default value. However, it lacks a full list of valid axis values (e.g., R, P, Y, RPY, etc.) and does not explain behavioral consequences like immediate effect or persistence, leaving the agent with incomplete information.

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 schema covers 100% of parameters but only labels 'value' as a UINT8 string. The description adds meaningful context by explaining that the parameter selects which axes the sliders control and provides the default 'RPY' as an example, significantly enhancing the agent's understanding beyond the schema.

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's function: setting simplified_pids_mode, which controls which axes the simplified PID sliders affect. It provides an example 'RPY = all axes', making the purpose unambiguous and distinct from numerous 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?

The description implies that the tool is used to configure PID slider axes but offers no explicit guidance on when to use this tool versus alternatives like set_pid_sliders. It does not specify prerequisites or exclusions, leaving the agent to infer context from the tool name alone.

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