generate_ramp

Build a shading ramp from a base color for pixel art, shifting shadows toward cool and highlights toward warm.

Instructions

Append a shading ramp built around a base color (dark to light). Shadows hue-shift toward cool, highlights toward warm.

Behavior3/5

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

The description discloses the hue-shift behavior (cool shadows, warm highlights) and implies appending rather than replacing. However, lacking annotations, it does not cover side effects on existing palette, required permissions, or error conditions.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences efficiently convey the core purpose and behavioral trait. No filler; front-loaded with the verb 'Append'.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given 5 parameters and no output schema, the description explains the high-level effect but omits parameter details, return values, and error scenarios. It is adequate but not fully comprehensive for an agent to use reliably.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The description only hints at the base_hex parameter via 'base color' and mentions no other parameters. With 60% schema coverage, the description adds little beyond what is in the schema, failing to explain steps, hue_shift, or name.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool appends a shading ramp around a base color, specifying dark-to-light progression and hue shifts. This verb-resource-action combination is distinct from sibling tools like 'shade' or 'set_palette_color'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives. It does not mention prerequisites, limitations, or compare to related tools like 'shade' or 'dither_gradient'.

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