Set VPD triggers

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

Annotations already indicate this is a mutating, idempotent, non-destructive operation. The description adds meaningful behavioral detail beyond those annotations by stating the partial-update semantics: only passed fields should change, implying unspecified triggers remain unaffected.

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?

Two front-loaded sentences with zero filler. It communicates the resource, units, precision, and update semantics without repeating anything already present in the schema or annotations.

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 rich schema, clear annotations, and existing output schema, the description is mostly sufficient for an agent to invoke the tool correctly. The notable gap is the lack of sibling differentiation and use-case context, but the core call semantics are clear and well-supported.

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?

Schema description coverage is 75%, so the schema already documents most parameters. The description adds value by clarifying the kPa unit, the one-decimal precision for trigger values, and the 'pass only what should change' partial-update model, which helps the agent interpret optional and null-default parameters correctly.

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?

States a specific verb ('Configure') and a specific resource ('VPD-mode high/low triggers'), with the added precision of kPa and one-decimal values. This is distinct from sibling tools like set_auto_triggers because it is explicitly VPD-mode focused.

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?

Provides no guidance on when to use this tool versus alternatives such as set_auto_triggers, nor any exclusions or prerequisites. The instruction 'Pass only what should change' is useful once the tool is already selected, but it does not help an agent choose this tool over siblings.

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