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

No annotations are provided, so the description carries the full behavioral burden, yet it discloses nothing about how non-Hangul characters, digits, spaces, or mixed-script input are handled, nor what the extracted output looks like. It does not contradict anything, but it also adds no behavioral context beyond the purpose statement.

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?

One short sentence with the resource and action front-loaded and no filler. It is efficient, though its brevity leaves it close to under-specification for a tool with no annotations.

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?

The existence of an output schema means return values need not be explained, and the input is trivially a single string. Still, for a tool with zero annotation coverage, the description should say at least how non-Hangul input is treated to be complete enough for confident invocation.

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 single parameter 'text' has 0% schema description coverage, so the description must compensate; '한글 텍스트에서' does signal that the input should be Korean text, which is meaningful. However, nothing is said about format, length limits, or expected character set beyond that hint.

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 a specific verb ('추출합니다' / extract) and a specific resource ('초성' / initial consonants) from Hangul text, which is clearly distinct from the sibling tools (number_to_korean, korean_holidays, is_korean_business_day). It stops short of 5 only because '초성' is domain jargon that an agent may not resolve without prior knowledge.

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?

There is no guidance on when to use this tool versus the Korean-related siblings, no prerequisites, and no mention of what input is unsuitable (e.g., non-Hangul or mixed text). The agent must infer usage entirely from the one-line purpose.

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