util_cbao

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

With no annotations, the description bears full responsibility. It fails to disclose whether the tool modifies existing colors, works on selections, or has side effects. The brief statement does not provide sufficient behavioral context.

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 extremely concise (7 words) but at the expense of clarity. It lacks necessary detail to be useful, making it more underspecified than efficiently concise.

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?

Given the low complexity (1 param, no annotations) and presence of an output schema, the description is too minimal. It fails to explain the coloring mechanism, selection scope, or behavior, leaving critical gaps for an agent.

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 one parameter ('selection') with 0% description coverage. The description adds no meaning beyond the schema, leaving the parameter unexplained. The tool name suggests coloring, but the parameter's role is unclear.

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 'Colors by atom, orange carbons,' indicating a specific action and target. However, it does not clarify which atoms are colored (only carbons? all atoms? ) or differentiate from sibling tools like util_cbab, which likely colors another element. The purpose is somewhat clear but vague.

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 provided on when to use this tool versus alternatives. The agent is left to infer from the name and summary that it colors carbons orange, but there is no explicit context or exclusions.

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