get_p_roll

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

No annotations, so description must provide behavioral insight. It warns of oscillations if value is too high, which is useful. However, it does not explicitly state that this is a safe read-only operation (though implied by 'get'). The UINT8 and default are mentioned. Overall adequate but not rich.

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?

Extremely concise: three short sentences with no filler. The behavioral warning is relevant and efficiently stated. The type/default is appended as a bracketed note. Excellent structure.

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?

Given the tool's simplicity (no parameters, no output schema), the description adequately covers purpose, value range, and tuning implication. It does not explicitly state 'returns current value' but that's clear from 'Get p_roll'. Could be considered nearly 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?

No parameters, so schema coverage is trivially 100%. The description adds context about the value's type (UINT8) and default (45), which helps the agent understand the returned data. This meets baseline expectation.

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?

Purpose is clearly stated as retrieving the Roll P gain, a proportional term reacting to angle error. The description differentiates from other gains (I, D) and from the set counterpart. It also provides a behavioral note about high values causing oscillations.

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?

No explicit guidance on when to use this tool versus alternatives like get_d_roll or set_p_roll. The description implies tuning context but does not state when to read vs set or compare to other gains.

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