set_scheduler_relax_osd

Adjust the OSD task's scheduler relaxation time between 0 and 500 μs to optimize CPU load and prevent task starvation.

Instructions

Set scheduler_relax_osd: Scheduler relaxation time for OSD task. [UINT16, 0–500, default: 25]

Input Schema

NameRequiredDescriptionDefault
valueYesValue for scheduler_relax_osd (UINT16, 0–500)
Behavior3/5

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

With no annotations, the description provides value constraints ('UINT16, 0–500, default: 25') but does not disclose behavior such as persistence, immediate effect, or side effects. The range and default add some transparency, but behavioral context is lacking.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence plus a bracket with type, range, and default. It is very concise and front-loads the purpose. However, the structure could be improved by placing the constraint info more naturally.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

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 basic purpose and value constraints. It does not explain what 'scheduler relaxation time' means or when to adjust it, which would be helpful for an agent unfamiliar with the domain.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% (one parameter described). The description adds the default value (25) beyond the schema, which enhances understanding. The type and range are already in the schema, so the description provides marginal added value.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'Set' and the resource 'scheduler_relax_osd', with a brief explanation 'Scheduler relaxation time for OSD task'. It distinguishes from many sibling 'set_' tools by naming the specific parameter, though it does not explicitly differentiate from the similar 'set_scheduler_relax_rx'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives, prerequisites, or when not to use it. The description only states what the tool does without any contextual usage instructions.

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