get_pid_sliders

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

No annotations are provided, but the description correctly characterizes this as a read-only operation ('get') that returns float values. It explains the meaning of the pids_mode field, adding transparency. However, it does not disclose any potential side effects or error conditions, which is acceptable for a simple getter.

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 concise with three sentences, each conveying essential information: purpose, return format, and pids_mode explanation. No unnecessary words or 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 tool with no parameters and no output schema, the description adequately explains what is returned and the meaning of the values. It does not list all possible slider values but provides enough context for an agent to interpret the output.

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 tool has no parameters, and schema coverage is 100%. The description adds value by explaining the return values (float positions, default 1.0) and the pids_mode enum, which goes beyond the empty 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 precisely states the tool retrieves 'current Betaflight simplified filter and tuning slider values' and explains the return format (float positions) and pids_mode enumeration. This clearly distinguishes it from other get_ tools by targeting a specific set of parameters.

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 explicitly guide when to use this tool versus alternatives. While it explains the return values, it lacks information about the context or prerequisites for retrieval, leaving the agent to infer applicability from the name and sibling tools.

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