Step 2: Run Linting

Step 3: Check Documentation Timestamps

echo ""

Step 4: Verify On Feature Branch

echo "🌿 Checking branch..."

CURRENT_BRANCH=$(git branch --show-current)

  echo "❌ CRITICAL: You're on $CURRENT_BRANCH (should be feature branch)"

Step 5: Check for Uncommitted Changes

echo ""
echo "💾 Checking for uncommitted changes..."

if ! git diff --quiet || ! git diff --cached --quiet; then
  echo "⚠️  Uncommitted changes found"
  echo "💡 Run: /commit-smart"
  UNCOMMITTED_PASS=false
else
  echo "✅ No uncommitted changes"
  UNCOMMITTED_PASS=true
fi

Step 6: Generate Report

echo ""
echo "━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━"
echo "📊 Pre-PR Check Summary"
echo "━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━"
echo ""

# Track overall pass/fail
ALL_PASS=true

if [ "$TESTS_PASS" = true ]; then
  echo "✅ Tests passing"
else
  echo "❌ Tests failing"
  ALL_PASS=false
fi

if [ "$LINT_PASS" = true ]; then
  echo "✅ Linting passing"
else
  echo "❌ Linting failing"
  ALL_PASS=false
fi

if [ "$TIMESTAMPS_PASS" = true ]; then
  echo "✅ Doc timestamps updated"
else
  echo "❌ Doc timestamps need update"
  ALL_PASS=false
fi

if [ "$BRANCH_PASS" = true ]; then
  echo "✅ On feature branch"
else
  echo "❌ NOT on feature branch"
  ALL_PASS=false
fi

if [ "$UNCOMMITTED_PASS" = true ]; then
  echo "✅ All changes committed"
else
  echo "⚠️  Uncommitted changes"
fi

echo ""
if [ "$ALL_PASS" = true ]; then
  echo "✅ All critical checks passed - Ready for PR!"
  exit 0
else
  echo "❌ Some checks failed - Fix issues before PR"
  exit 1
fi

Integration with /submit-pr

/submit-pr workflow:
  1. Runs /techdebt (checks for tech debt)
  2. Runs /pre-pr-check (THIS SKILL)
  3. If any CRITICAL failures → STOP
  4. If warnings only → Continue with note
  5. Creates PR
  6. Starts /pr-review

Handling Test Failures

If tests fail 3+ times in a row:

Document failures in PR description
Include error messages
Explain why tests can't be fixed immediately
Submit PR with failing tests noted

This is allowed - better to get code review than block on flaky tests.

Manual Checks (Codex performs)

In addition to automated checks, Codex should verify:

Code follows project conventions
No obvious bugs or security issues
Changes are focused and cohesive
PR won't be too large (suggest splitting if >500 lines)
Breaking changes documented
