set_theme_color

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

With no annotations provided, the description carries the full burden of disclosing behavior. It does convey the color format ('#rrggbb[aa]' or 'Color(r, g, b, a)') and implies an override semantics, but it fails to mention side effects, reversibility, or what happens if the control lacks a theme. This is limited but non-empty 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, front-loaded sentence that identifies the operation and then provides essential format details. It is concise with no filler, effectively using its limited length to convey the core purpose and a key parameter 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?

Despite the presence of many theme-related sibling tools, the description lacks sufficient context to fully guide an agent. It does not explain how this tool differs from set_theme_constant or set_theme_stylebox, and it does not mention return values or side effects. The gaps are critical given the lack of annotations and output schema.

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?

The input schema has no descriptions (0% coverage), so the description must clarify all parameters. It only explains the 'color' parameter format, while 'node_path' and 'name' remain ambiguous. The description does not add meaning to these two parameters, leaving a significant gap in parameter understanding.

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 ('Add a theme color override') and the target resource ('a Control'), which distinguishes it from sibling tools like set_theme_constant or set_theme_stylebox that handle different theme property types. The verb 'Add' is specific, and the scope is unambiguous.

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 implies usage context by mentioning 'on a Control' and 'theme color override', which suggests it is intended for overriding theme colors on controls. However, it does not explicitly state when to use this tool versus alternatives like set_theme_constant or set_theme_font_size, nor does it mention exclusions or prerequisites.

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