set_ocio_colorspace

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

With no annotations, the description carries full behavioral burden. It describes the pipeline modification and conversion to scene-linear, and mentions default behavior for omitted source_node. However, it does not mention potential side effects like overwriting previous OCIO settings.

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 with no wasted words. It front-loads the one-line summary and then provides details in a clear, structured format.

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 tool has an output schema, the description doesn't need to explain return values. It covers purpose, behavior, and parameters adequately. Could mention prerequisites (e.g., requiring an existing source) but overall complete for a simple operation.

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 description adds significant meaning beyond the input schema, which has 0% coverage. It provides examples for colorspace ('sRGB - Texture', 'ACEScg') and explains the source_node parameter with format and default behavior.

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 tool sets the OCIO input color space for a source and explains it inserts an OCIOFile node. This distinguishes it from sibling tools like set_ocio_display or set_ocio_look.

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 explains what the tool does but does not explicitly provide guidance on when to use it versus alternatives or when not to use it. Usage is implied by the description of the action.

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