set_lut

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

Annotations are absent, so the description carries the burden. It discloses file formats and target options but omits behavioral details like whether it overrides existing LUTs, immediate activation, or side effects on other settings. Adequate but missing common aspects.

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 concise, front-loaded with the main purpose, and structured with an 'Args' section. Each sentence adds value; no redundant content.

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?

Covers essential aspects like action, file types, and targets. Lacks details on error handling, return values (output schema exists but not explained), global vs. per-clip application, and behavior when target already set. Mostly complete with minor gaps.

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 coverage is 0%, but the description adds significant meaning by explaining both parameters: lut_file_path (with file extensions) and target (with options and their roles). Compensates well for the lack of schema descriptions, though could add format specifics.

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 the action ('Load a LUT file and activate it'), specifies the resource (LUT), and mentions the function (apply color transformations). It distinguishes from siblings like clear_lut by its unique purpose.

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 guidance on when to use (loading LUTs) and specifies three target options ('look', 'linearize', 'display'). However, it does not explicitly mention when not to use or alternative tools (e.g., clear_lut for removal), though the context is clear.

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