Set Graphics White Luminance

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

Annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=false, and openWorldHint=false. The description adds only the project-level HDR context, but does not disclose accepted value ranges, persistence behavior, permissions, or side effects beyond what the annotations provide.

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?

A single front-loaded sentence with no redundant phrases. It states the action and scope immediately and is appropriately sized for a one-parameter setter.

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 low complexity, the presence of an output schema, complete parameter schema coverage, and annotations covering safety traits, the description is largely complete. It could be improved by noting the valid luminance range or project-specific prerequisites, but it provides enough context for an agent to call the 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?

Schema description coverage is 100%, so the parameter's unit ('nits') is already documented by the schema. The description reinforces that this is the graphics white luminance HDR setting but adds no syntax, range, or formatting details beyond the 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 states a specific verb and resource ('Set the graphics white luminance value') with clear project scope and HDR context. It distinguishes itself from the sibling getter get_graphics_white_luminance by the verb 'set'.

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 gives no when-to-use guidance, no prerequisites, and no alternatives. It only states what the tool does, not when an agent should choose it over the related getter or other sequence setting tools.

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