save_custom_palette

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

With no annotations, the description carries the full burden. It usefully discloses the Kiln Pro entitlement requirement, which is important context beyond the schema, but it does not state whether an existing palette with the same name is overwritten, whether names must be unique, or what happens on save.

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 purpose is front-loaded in one useful sentence, but two of the three sentences are upsell copy and a pricing URL that do not help an agent select or invoke the tool correctly.

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 save operation with no annotations and low schema description coverage, the description should clarify required inputs and persistence behavior. It covers the basic purpose and tier gate but leaves too much about parameters and save semantics unstated.

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 only 33%, and only the optional texture parameter is described in the schema. The description mentions 'any texture' but does not explain the required name or the expected structure of the colors array, so it does not compensate for the low schema coverage.

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 first sentence states a specific verb and resource: saving a custom color palette for reuse with any texture. It is clear which operation this performs, though it does not explicitly distinguish itself from sibling tools such as list_custom_palettes or delete_custom_palette.

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 says the palette is for reuse with any texture, but gives no explicit when-to-use guidance, no exclusions, and no alternatives. The remaining sentences are marketing and upgrade prompts rather than invocation guidance.

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