Shared Validation Feedback Loops

Feedback Loops

"Validate early, validate often – catch errors before they compound."

When to Use This Skill

Use before every task related changes commit to ensure code quality and prevent broken builds.

Quick Start

⚠️ PRE-REQUISITE: Test Coverage Check (BLOCKING)

Before running feedback loops, verify test coverage exists:

# Check for modified files without tests
git diff --name-only HEAD~5 | grep '^src/' | while read file; do
  test_file="src/tests/${file#src/}"
  test_file="${test_file%.ts}.test.ts"
  if [ ! -f "$test_file" ]; then
    echo "COVERAGE GAP: $file missing $test_file"
  fi
done

# If coverage gaps found: BLOCK - invoke test-creator

Then run all feedback loops in sequence:

npm run type-check && npm run lint && npm run build

Anti-Patterns

❌ DON'T:

• Commit without running feedback loops
• Use @ts-ignore or // eslint-disable to hide errors
• Use any type without justification

✅ DO:

• Run all loops before every commit
• Fix errors properly, don't suppress
• Add types to all public interfaces
• Run --fix for auto-fixable issues
