Security Audit: $ARGUMENTS

Scan for vulnerabilities and automatically fix them in an isolated worktree.

Process

1. Create Isolated Worktree

TIMESTAMP=$(date +%Y%m%d-%H%M%S)
WORKTREE_PATH="../audit-fix-$TIMESTAMP"
git worktree add "$WORKTREE_PATH" -b "security-audit-$TIMESTAMP"
cd "$WORKTREE_PATH"

2. Run Security Audit

npm audit --json > audit-report.json

If no vulnerabilities, clean up and exit.

3. Categorize by Severity

Parse audit results:

• Critical: Immediate action required
• High: Serious risk, patch ASAP
• Moderate: Should fix soon
• Low: Fix when convenient

4. Determine Strategy

• 1-3 packages: Update sequentially
• 4+ packages: Use parallel Task subagents (2 packages per agent)

5. Update Packages

For each package:

npm install <package>@latest

Then validate:

npm run build && npm run lint && npm test

If validation fails, revert to previous version.

6. Post-Audit Scan

npm audit

Compare before/after vulnerability counts.

7. Report and Prompt

Generate security report with:

• Initial vs remaining vulnerabilities
• Successfully updated packages
• Failed updates with reasons
• Recommendations for remaining issues

Prompt: merge fixes, keep for review, or discard.

8. Cleanup

git worktree remove "$WORKTREE_PATH"
git branch -d "security-audit-$TIMESTAMP"

Parallel Execution

When >3 packages, split into groups and launch Task subagents:

Task({
  subagent_type: 'general-purpose',
  prompt: 'Update packages X, Y with full validation...',
  run_in_background: true
})

Collect results from all agents before generating final report.
