set_palette

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

No annotations are provided, so the description must fully disclose behavioral traits. It only states the general operation without discussing side effects (e.g., overwriting existing palette), required permissions, or impact on other elements. The lack of details limits transparency.

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 a single concise sentence without excess. It front-loads the core action and target. However, given the complexity of the tool (two parameters, no annotations), brevity sacrifices necessary detail.

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?

The tool has two required parameters, no output schema, and no annotations. The description should cover parameter details, expected input format, error conditions, and behavioral nuances. It only covers the colors parameter partially and omits filename entirely, making it incomplete.

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 must explain both parameters. It clarifies that 'colors' is a list of hex color codes, adding meaning beyond the schema. However, 'filename' is left unexplained—its purpose and expected format are missing, which is a significant gap.

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 action ('Set'), the target ('active sprite palette'), and the method ('using a list of hex colors'). It differentiates from siblings like 'get_palette' by indicating a write operation. However, it does not specify whether the palette is fully replaced or partially updated, leaving slight ambiguity.

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?

No guidance on when to use this tool versus alternatives like 'remap_colors_in_cel_range'. No context on prerequisites (e.g., an active sprite must exist) or conditions where this tool is appropriate. The description provides no decision-making support.

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