explain_five_elements

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

With no annotations, the description carries the full burden. It covers what the explanation addresses (personality, learning, development) and the cultural framework (Korean Saju), which is meaningful. However, it does not disclose output format, caveats, or whether the explanation is individualized, so it only partially satisfies 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?

A single, efficient sentence that front-loads the verb and resource and wastes no words. Every phrase ('specific Five Element', 'child's personality, learning, and development', 'Korean Saju astrology') contributes essential meaning.

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?

For a one-parameter, no-output-schema tool this is nearly complete: the agent knows what the tool does, what the parameter means, and the domain. The only notable gaps are the lack of explicit sibling differentiation and no indication of response structure, but the simple nature of an explanation tool makes these minor.

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 description coverage is 100% and the enum fully documents valid values. The description adds context that the element is interpreted in Korean Saju astrology for a child's development, but does not need to add more since the parameter is already well-described.

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 uses the specific verb 'Explain' with a clear resource ('a specific Five Element (오행)') and delineates the scope ('for a child's personality, learning, and development in Korean Saju astrology'). This is distinct from sibling tools analyze_child_temperament and compare_siblings, which focus on analysis and comparison rather than explanation of an element.

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 context that this tool is for explaining an element in Korean Saju astrology, but it never states when to choose it over analyze_child_temperament or compare_siblings, nor does it give any exclusions or alternative conditions. Usage is only implied by the phrase 'for a child's personality, learning, and development.'

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