You paste

Python → TypeScript: def avg(xs): return sum(xs) / len(xs)

You get

const avg = (xs: number[]) => xs.length ? xs.reduce((a, b) => a + b, 0) / xs.length : NaN;

Difference: Python raises ZeroDivisionError on []; this returns NaN — throw if you need parity.

About this skill

About Code translator

Porting code between languages line by line produces code that works differently in subtle ways. This skill translates into idiomatic code for the target language, maps libraries to their standard equivalents and then lists every behaviour that differs — integer division, null handling, dates, string encoding and error behaviour. It finishes with parity tests you can run against both versions to prove they agree. Use it for migrations, for porting a snippet from documentation, or for learning how a familiar pattern is written in a new language without picking up bad habits.

# Skill: Code translator

You are running the "Code translator" skill for me. I work as: Software engineer. What I need from you: idiomatic code in the target language with notes on every behaviour that differs.

## When I send you the source code, its language and the target language or framework
1. Translate into idiomatic target-language code, not a line-by-line copy.
2. Map libraries to the standard equivalents.
3. List behaviour differences (integer division, null handling, dates, encoding).
4. Give a few test cases to prove both versions agree.

## Reply in this format
- Translated code
- Library mapping
- Behaviour differences
- Parity tests

## Rules
- Use only the facts I give you; mark anything you had to assume with [ASSUMPTION].
- If something essential is missing, ask me one short question, then continue.
- No preamble or filler: start with the result.

Confirm you're ready in one line, then wait for me to send the source code, its language and the target language or framework.

Then sendThe source code, its language and the target language or framework. For example: Python → TypeScript: def avg(xs): return sum(xs) / len(xs)

Architecture decision record

ProblemBig technical decisions get made in meetings and forgotten, so the team re-argues them a year later.

You paste

Choosing a queue: Redis streams vs RabbitMQ vs SQS for 2k jobs/min, team of 4, on AWS

You get

Decision: Amazon SQS.

Why: managed, scales past 2k/min, the team already runs on AWS.

Harder: local development needs LocalStack. Revisit if we leave AWS.

Immediate resultAn ADR with context, options considered, the decision and its consequences, ready to commit.

ProblemThousands of log lines hide the one pattern that explains the outage.

You paste

500 lines of nginx + app logs from 09:00–09:20

You get

upstream timed out (110) — 212 lines, first 09:04:11

DB pool exhausted — 198 lines, first 09:04:09 (2 s earlier)

Likely culprit: database, not nginx. Next: check slow query log 09:03–09:05.

Immediate resultGrouped error patterns with counts, first-seen times and the most likely culprit.
