Repomix Safe Mixer

Overview

Safely package codebases with repomix by automatically detecting and removing hardcoded credentials.

This skill prevents accidental credential exposure when packaging code with repomix. It scans for hardcoded secrets (API keys, database credentials, tokens), reports findings, and ensures safe packaging.

When to use: When packaging code with repomix for distribution, creating shareable reference packages, or whenever security concerns exist about hardcoded credentials in code.

Core Workflow

Standard Safe Packaging

Use safe_pack.py from this skill's scripts/ directory for the complete workflow: scan → report → pack.

python3 scripts/safe_pack.py <directory>

What it does:

1. Scans directory for hardcoded credentials
2. Reports findings with file/line details
3. Blocks packaging if secrets found
4. Packs with repomix only if scan is clean

Example:

python3 scripts/safe_pack.py ./my-project

Output if clean:

🔍 Scanning ./my-project for hardcoded secrets...
✅ No secrets detected!
📦 Packing ./my-project with repomix...
✅ Packaging complete!
   Package is safe to distribute.

Output if secrets found:

🔍 Scanning ./my-project for hardcoded secrets...
⚠️  Security Scan Found 3 Potential Secrets:

🔴 supabase_url: 1 instance(s)
   - src/client.ts:5
     Match: https://your-project-ref.supabase.co

❌ Cannot pack: Secrets detected!

Options

Custom output file:

python3 scripts/safe_pack.py \
  ./my-project \
  --output package.xml

With repomix config:

python3 scripts/safe_pack.py \
  ./my-project \
  --config repomix.config.json

Exclude patterns from scanning:

python3 scripts/safe_pack.py \
  ./my-project \
  --exclude '.*test.*' '.*\.example'

Force pack (dangerous, skip scan):

python3 scripts/safe_pack.py \
  ./my-project \
  --force  # ⚠️ NOT RECOMMENDED

Standalone Secret Scanning

Use scan_secrets.py from this skill's scripts/ directory for scanning only (without packing).
