color_apply_drx

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only says 'apply' without clarifying whether the grade is destructive, whether it creates a new version, or if it operates on the current timeline. This lack of side-effect information is a significant gap for a mutation tool.

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 a single, front-loaded sentence with no wasted words. It efficiently states the action, resource, and target, making it highly concise and easy to parse.

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 availability of a complete schema and an output schema, the description is minimally viable but leaves gaps: it does not mention the timeline context, potential destructive effects, or when to use this tool against alternatives. These gaps could lead to improper invocation without external knowledge.

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% with all five parameters documented, so the baseline is 3. The description adds minimal semantic value by relating 'one or more items' to item_names but does not explain grade_mode values or track defaults beyond what the schema already states.

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 uses the specific verb 'apply' with a clear resource 'DaVinci Resolve grade preset (.drx)' and target 'one or more items', which effectively communicates the core function. It distinguishes this tool from sibling tools like color_set_lut or gallery_apply_grade_from_still by focusing on .drx preset application.

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 provides no guidance on when to use this tool versus alternatives, nor does it mention prerequisites or related tools like drx_inspect for validation. With no context beyond a single sentence, an agent must guess the appropriate invocation scenario.

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