get_colors

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

With no annotations provided, the description carries the burden of disclosing behavior. It mentions the return format ('List of available colors with IDs and hex values') but does not explicitly state that the operation is read-only or safe. This is adequate for a simple getter but lacks explicit disclosure of side effects or implications.

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 and well-structured: a clear one-line purpose, a 'Use this when' list, and a return format note. Every sentence adds value without fluff, making it efficient and front-loaded.

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?

For a simple parameterless getter with no output schema, the description fully covers purpose, usage scenarios, and return format. No additional context is needed given the tool's trivial nature and the absence of parameters.

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 input schema has zero parameters, so there is nothing for the description to clarify. The schema coverage is trivially 100%, and the description adds no parameter-level detail because none exist. Per rubric, baseline is 4 since no compensation is needed.

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 returns available color options for Skylight profiles and lists, using a specific verb ('Get') and resource ('color options'). This distinctly separates it from sibling tools like get_lists or get_family_members, which serve different purposes.

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?

Provides explicit 'Use this when' scenarios (choosing colors, setting list colors, exploring options) that give clear context for invocation. However, it does not mention alternatives or exclusions, which is acceptable given no close siblings, but stops short of a perfect 5.

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