apply_palette_preset

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states the action but does not explain side effects (e.g., whether it modifies the sprite in place, affects all frames, requires an existing sprite, or returns a result). This is insufficient for a mutation tool.

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 sentence, which is concise and front-loaded. However, it is so brief that it omits critical usage and parameter details, making it less effective. It earns its place but could be more informative without becoming verbose.

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 tool with two required parameters, no output schema, and no annotations, the description is incomplete. It does not explain how to specify the preset or what the expected outcome is. An agent would struggle to invoke it correctly without additional information.

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 is 0%, and the description does not clarify the parameters. It hints at the preset parameter by mentioning 'built-in retro palette preset' but does not list valid preset values or explain what 'filename' refers to. No guidance on parameter format or required context.

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 states a specific verb 'apply' with a clear resource 'built-in retro palette preset' and target 'sprite'. This clearly distinguishes it from siblings like list_palette_presets (which lists) and set_palette (which sets a palette directly). It is unambiguous what the tool does.

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 is given on when to use this tool versus alternatives such as set_palette, list_palette_presets, or extract_palette. The description does not mention prerequisites, typical use cases, or situations where this tool should be preferred over others.

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