npm run build 2>&1 | oops

The Problem

Your build breaks. You stare at a 40-line stack trace. You copy the error, open a browser, paste it into Google, click three Stack Overflow links, try two solutions that don't work, and finally find the fix 15 minutes later.

Meanwhile, your flow state is gone.

Quick Start

npx oops-ai                                # Use without installing
# or
npm install -g oops-ai                     # Install globally

export ANTHROPIC_API_KEY="sk-ant-..."      # Get one at console.anthropic.com

Then pipe any error:

npm run build 2>&1 | oops
python script.py 2>&1 | oops
cargo build 2>&1 | oops
docker build . 2>&1 | oops
kubectl logs pod/api-xyz 2>&1 | oops

The 2>&1 redirects stderr to stdout so oops catches all error output.

Before → After

$ npm run build
Error: Cannot find module 'express'
    at Function.Module._resolveFilename
    ...45 more lines...

*copy → Google → SO → try → fail → repeat*

$ npm run build 2>&1 | oops

Problem: Cannot find module 'express'

Solution:
  $ npm install express

Done. 0.8s ✓

Examples

Rust Borrow Checker

$ cargo build 2>&1 | oops

Problem: Cannot borrow `users` as mutable while borrowed as immutable

Solution: Limit the lifetime of the immutable borrow

  let first_name = users[0].name.clone();
  users.push(new_user);     // Now OK
  println!("{}", first_name);

Docker Build Failure

$ docker build -t myapp . 2>&1 | oops

Problem: Dockerfile parse error - unexpected EOF at line 12

Solution: Missing backslash in multi-line RUN command

  RUN apt-get update && \
      apt-get install -y curl

Git Push Rejected

$ git push origin main 2>&1 | oops

Problem: Remote contains commits you don't have locally

Solution:
  $ git pull --rebase origin main
  $ git push origin main

Kubernetes Pod Crash

$ kubectl logs pod/api-7d9f8b-xk2m 2>&1 | oops

Problem: ECONNREFUSED 10.0.0.5:5432 — Can't reach PostgreSQL

Solution:
  1. Check DB service: kubectl get svc postgres-service
  2. Verify DB_HOST env var in deployment
  3. Test: kubectl run debug --image=postgres:15 ...

Use Cases

• Stay in flow — Get solutions without leaving the terminal
• Onboard faster — Clone a new repo, pipe errors instead of asking teammates
• Debug production — kubectl logs ... | oops when every second counts
• Learn new languages — Rust borrow checker, Go interfaces explained instantly
• Pre-commit check — npm test 2>&1 | oops before pushing broken code

How It Works

1. Reads error output from stdin
2. Auto-detects language/framework
3. Sends to Claude AI for analysis
4. Returns concise, actionable fix (~0.5–1.5s)

Supported Languages

JavaScript · TypeScript · Python · Go · Rust · Java · C/C++ · Ruby · PHP · Docker · Kubernetes · Git · Shell · PostgreSQL · MySQL · and more

Options

-v, --verbose    Detailed analysis with multiple approaches
--no-color       Disable colored output
-V, --version    Show version
-h, --help       Show help

Pro Tips

# Shell aliases for speed
alias oops-build='npm run build 2>&1 | oops'
alias oops-test='npm test 2>&1 | oops'

# Trim huge output for faster analysis
docker build . 2>&1 | tail -100 | oops

# Save solutions for later
npm run build 2>&1 | oops > solution.txt

# Git pre-commit hook
npm test 2>&1 | oops || exit 1

vs Alternatives

Privacy

Error text is sent to Anthropic's API for analysis. Don't pipe sensitive data (passwords, API keys, tokens).

Requirements

• Node.js 18+
• Anthropic API key (ANTHROPIC_API_KEY)
