util_cbay

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

No annotations provided. Description only states coloring action without disclosing side effects, scope of changes, or whether it is non-destructive. For a coloring tool, missing details on how it interacts with existing colors.

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?

Description is very short (one line), which is concise but lacks structured information. It does not waste words, but underspecifies key details, making it insufficient.

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's simplicity and lack of annotations, the description fails to provide enough context for an agent to understand its behavior. The output schema exists but its content is unknown; description should clarify what the tool returns.

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?

Parameter 'selection' has no description in schema (0% coverage) and description does not explain how it affects coloring. Agent cannot determine how to use the parameter correctly.

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?

Description 'Colors by atom, yellow carbons' is ambiguous: it's unclear whether it colors all atoms yellow or specifically carbon atoms yellow. The phrase '(Color By Atom, Yellow)' adds confusion. Lacks a specific verb and resource distinction from sibling tools.

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 on when to use this tool versus alternatives like util_cbab, util_cbac, etc. No context for typical use cases or when to avoid.

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