set_ocio_look

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

No annotations are provided, so the description carries full burden. It explains the basic insertion action but does not disclose error behavior (e.g., invalid look name), idempotency, or side effects on existing looks. More details on state changes and prerequisites are needed.

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 well-structured with a purpose sentence, a brief explanation, and arg descriptions. It is not overly verbose, though the 'Args' section could be slightly more compact without losing clarity.

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 that an output schema exists, the description does not need to detail return values. However, it lacks mention of return behavior or success/failure indicators. The tool modifies state, and for a workflow with many siblings, more contextual completeness about preconditions (e.g., valid look) would improve usability.

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?

With 0% schema description coverage, the description adds value for all parameters: 'look' as name from OCIO config, 'direction' as allowed strings, and 'source_node' as optional group name with default. However, it does not explain how to obtain look names or config details, which could be assumed from sibling tools.

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 applies an OCIO look to a source by inserting an OCIOLook node into the look pipeline. It uses specific verb+resource phrasing and distinguishes from siblings like set_ocio_colorspace and set_ocio_display.

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 implies when to use the tool (when applying a named look from the OCIO config) but does not explicitly compare with alternatives or state when not to use it. The optional parameter guidance ('If omitted, uses the first source') is helpful but incomplete.

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