Nudge Fill Light Elevation Down

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

With no annotations, the description discloses the automatic state querying behavior, which is helpful. However, it does not mention any potential side effects, or if there are any specific permissions needed (e.g., editing a scene). For a simple nudge tool, this is adequate but could be more thorough.

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 two sentences long, front-loads the core purpose, and every sentence adds value with no redundancy. It is optimally concise for the complexity of the tool.

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 no output schema and no annotations, the description covers the essential: what the tool does and its automatic state refresh. However, it could briefly note that the adjustment is relative and the default value (though present in the schema). Still, it is quite complete for a simple tool.

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 input schema already fully describes the 'degrees' parameter with a description and default, achieving 100% coverage. The tool description does not add extra meaning beyond what the schema provides, so a baseline score of 3 is appropriate.

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 'Adjust the fill light elevation downward relative to current position,' which is a specific verb+resource. It implicitly distinguishes from sibling tools like nudge_fill_light_elevation_up and nudge_key_light_elevation_down by specifying 'downward.'

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 notes that the tool automatically queries fresh state before adjustment, ensuring accuracy even after manual moves. This provides clear context for when to use it, but does not explicitly state when not to use or provide alternatives among the many sibling tools.

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