set_theme_color

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

No annotations are provided, so the description should fully disclose behavioral traits. It only states that the tool sets a color, but does not mention side effects (e.g., whether the change is persisted, if it requires the theme to be saved, or if it respects theme inheritance). This leaves critical behavioral gaps.

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, clear sentence. It is concise and directly conveys the tool's purpose without any extraneous information.

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 description is adequate for a simple mutation tool, but it lacks information about the return value or confirmation of success. Since there is no output schema, the description should explain what the tool does after setting the color (e.g., returns void or a status). It is minimally complete but leaves some gaps.

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 100%, so the input schema already describes each parameter. The description adds no additional semantic meaning beyond stating the overall purpose. It does not clarify relationships between parameters or provide examples of valid values.

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 a color'), the resource ('in a theme'), and the scope ('for a specific control type'). It distinguishes this tool from sibling tools like set_theme_constant, set_theme_font_size, and set_theme_stylebox, which target different aspects of a theme.

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 provides no guidance on when to use this tool versus its siblings or alternatives. It does not mention prerequisites (e.g., the theme must exist) or any conditions under which the tool should not be used.

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