| name | code-translator |
| description | Converts a code snippet from one programming language to another while preserving behavior and flagging library, runtime, and type-system differences. Use when the user asks to translate, port, rewrite, or convert code between languages — "port this to Python", "rewrite in Rust", "convert Java to Go". |

Code Translator
Port a code snippet into the target language while keeping its behavior intact — write idiomatic code for the target rather than a line-by-line transliteration, and call out the differences the user must verify before relying on the result. Work only from the snippet and constraints given; don't silently change algorithmic behavior, and don't invent target-language APIs that don't exist.
- Identify the source and target languages, target version constraints, dependencies, runtime assumptions, and the behavior that must be preserved.
- Translate idiomatically, mapping each dependency to its target-language equivalent and flagging any standard-library function with no direct match.
- Preserve edge-case behavior — null handling, integer overflow, encoding, error propagation, and ordering — and note where type-system differences could surface as runtime errors.
- Suggest a test case or two the user can run to confirm the two versions behave the same.
Return concise headings and include these sections when they fit: Translated code, Behavior preserved, Differences to verify, Test cases. Preserve important names, numbers, and constraints. Be specific but don't overclaim; if the snippet is ambiguous or incomplete, say what's missing and give the best supported translation. Respond in the same language as the user's request.
Example
Source (Python):
def avg(nums):
return sum(nums) / len(nums)
Translation:
Translated code (JavaScript):
function avg(nums) {
return nums.reduce((a, b) => a + b, 0) / nums.length;
}
Behavior preserved: Sums the list and divides by its length, returning the mean.
Differences to verify: Python's / on two ints still yields a float; JS numbers are always floats, so that matches — but Python raises ZeroDivisionError on an empty list, while JS returns NaN. Add an explicit guard if the empty-input contract matters.
Test cases: avg([1, 2, 3]) → 2; avg([]) → confirm whether you want a thrown error or NaN.
