Chinese Simplified/Traditional & Japanese Kanji converter. 支援中文繁簡轉換（台灣/香港/大陸用語）及日本語新旧字体変換。
Scored across 1 tool
Only one tool exists, so there is no risk of selecting the wrong tool. The internal modes (simplified_to_traditional, traditional_to_simplified, japanese_modernize) are clearly enumerated in the description, making the single tool's purpose unambiguous.
The sole tool uses a clear, simple verb ('convert') that directly matches its function. With only one tool, naming consistency is trivially perfect.
A single tool for a focused text-conversion utility is thin per the rubric's guidelines, though it bundles three distinct conversion modes via parameters. It is borderline rather than a severe mismatch.
The tool covers simplified↔traditional Chinese (both directions) and Japanese old→new modernization. Minor gaps include no reverse Japanese new→old conversion, but the core domain is well covered.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden and largely meets it: it discloses the target conventions for each mode, including Taiwan/Hong Kong vocabulary standards and the full-width to half-width normalization in japanese_modernize. It does not state that the operation is stateless/non-destructive or mention input size limits, but for a pure text transformation these are minor gaps.
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 content is front-loaded and the per-mode bullets are efficient, but the entire body is duplicated once in Chinese and once in Japanese, roughly doubling length with translated repetition. The redundancy may serve human multilingual readers, yet it costs an agent tokens without adding new information.
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 two-parameter transformation tool with an output schema (so return values need not be explained) and full schema coverage, the description covers all three modes and their semantics adequately. The only missing pieces are operational details like idempotency and input size limits.
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%, so a baseline of 3 applies, but the description goes beyond the schema by giving meaning to each enum value rather than just listing the literals. It adds real semantics for the mode parameter and identifies text as the input, though it adds nothing about format constraints on text.
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 tool name 'convert' is generic and tautological on its own, but the description immediately narrows it to Chinese Simplified/Traditional and Japanese typographic conversion, which is specific and unambiguous. No siblings exist to differentiate from, so the missing sibling contrast is not penalized.
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 three modes are each explained with their source and target scripts, which effectively tells the agent which mode to select for a given input. There is no explicit when-not-to-use or statement of limitations (e.g., text length, mixed-script input), so it stops short of a 5.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
