mix_palette_colors

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

Discloses append vs overwrite behavior and interpolation parameter t, but lacks details on error handling, side effects, or return value. Adequate but incomplete.

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?

Two sentences with front-loaded purpose and compact details. No unnecessary words.

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 key aspects but missing return value, error conditions, and prerequisites (e.g., palette existence). Adequate for simple tool but not thorough.

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 67% (4 of 6 parameters described). Description adds value by explaining t interpolation and into_index overwrite behavior, but does not describe the name parameter.

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?

Description clearly states it blends two palette colors and stores the result, with specific details about interpolation. Distinct from sibling tools like set_palette_color or add_palette_color.

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?

Explicitly states it's for creating in-between shades via interpolation, implying use case. No explicit when-not-to-use or comparison to alternatives, but context is clear.

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