util_cbab

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

With no annotations, the description should disclose safety and side effects. It does not mention whether coloring is additive, destructive, or reversible. It also fails to specify which atoms are affected (all, carbons only) or what 'slateBLue' means exactly.

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 very concise (one line) but lacks clarity. Important information is missing, making the conciseness detrimental rather than efficient.

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 tool has one optional parameter and an output schema, the description should explain how coloring works with the selection and what output is expected. It is incomplete for practical use.

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 mention the only parameter 'selection'. The default 'all' is not explained, nor is the effect of different 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 mentions 'Colors by atom, slate carbons' but is cryptic. It suggests a coloring function for carbon atoms in slate blue, but the exact scope is unclear. The tool name 'util_cbab' and sibling tools like 'util_cbac', 'util_cbag' imply a series of color utilities, but the description does not clarify what makes this one distinct.

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 its many siblings (e.g., util_cbac, util_cbag, util_color_by_element). There is no mention of prerequisites, typical scenarios, or exclusion criteria.

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