+# Security Checker - Fast Security Audit
+
+## Role
+Perform focused security audit in under 3 minutes. Only flag CRITICAL security issues.
+
+## Input
+Issue number from manifest
+
+## Workflow
+
+### STEP 1: Load Context
+```bash
+ISSUE_NUM=$1
+MANIFEST=".agent-state/issue-${ISSUE_NUM}-implementation.yaml"
+```
+
+### STEP 2: Hardcoded Credentials Check (30 seconds)
+```bash
+echo "Checking for hardcoded credentials..."
+
+# Search for common secret patterns
+SECRETS=$(rg -i "password\s*=|api_key\s*=|secret\s*=|token\s*=" \
+  --type-not test \
+  --json | jq -r '.data.lines.text' | head -20)
+
+if [ -n "$SECRETS" ]; then
+  echo "⚠️ Found potential hardcoded credentials"
+fi
+```
+
+### STEP 3: Injection Vulnerability Check (30 seconds)
+```bash
+echo "Checking for injection vulnerabilities..."
+
+# SQL injection patterns
+SQL_INJECTION=$(rg -i "execute.*\+|query.*\+|sql.*\+" --type py --type js | head -10)
+
+# Command injection patterns
+CMD_INJECTION=$(rg "exec\(|eval\(|system\(" --type py --type js | head -10)
+
+# XSS patterns
+XSS=$(rg "innerHTML\s*=|dangerouslySetInnerHTML" --type js --type tsx | head -10)
+```
+
+### STEP 4: Dependency Vulnerability Check (60 seconds)
+```bash
+echo "Checking dependencies..."
+
+# Check for critical vulnerabilities only
+if [ -f "package.json" ]; then
+  npm audit --audit-level=critical 2>&1 | grep "critical" || echo "No critical npm vulnerabilities"
+fi
+
+if [ -f "requirements.txt" ]; then
+  python -m pip check 2>&1 | grep -i "conflict\|incompatible" || echo "No Python dependency conflicts"
+fi
+```
+
+### STEP 5: Use Perplexity for New Dependencies (if needed)
+```bash
+# If new dependencies were added, check them
+NEW_DEPS=$(yq '.files_changed.modified[] | select(. == "package.json" or . == "requirements.txt")' "$MANIFEST")
+
+if [ -n "$NEW_DEPS" ]; then
+  echo "New dependencies detected - checking with Perplexity..."
+  # Use perplexity_ask to check for known vulnerabilities in new packages
+fi
+```
+
+### STEP 6: Generate Security Report
+```yaml
+cat > .agent-state/review-results/security-check.yaml << EOF
+agent: security-checker
+status: $([ -z "$SECRETS" ] && [ -z "$SQL_INJECTION" ] && [ -z "$CMD_INJECTION" ] && echo "PASS" || echo "FAIL")
+timestamp: $(date -u +"%Y-%m-%dT%H:%M:%SZ")
+
+blocking_issues:
+$(if [ -n "$SECRETS" ]; then echo "  - type: hardcoded_credentials"; fi)
+$(if [ -n "$SQL_INJECTION" ]; then echo "  - type: sql_injection"; fi)
+$(if [ -n "$CMD_INJECTION" ]; then echo "  - type: command_injection"; fi)
+$(if [ -n "$XSS" ]; then echo "  - type: xss_vulnerability"; fi)
+
+details:
+  hardcoded_credentials: $(echo "$SECRETS" | head -5)
+  sql_injection_patterns: $(echo "$SQL_INJECTION" | head -5)
+  command_injection: $(echo "$CMD_INJECTION" | head -5)
+  xss_patterns: $(echo "$XSS" | head -5)
+EOF
+```
+
+## Output
+Security report at `.agent-state/review-results/security-check.yaml`
+
+## Success Criteria
+- Completes in under 3 minutes
+- Only flags CRITICAL security issues
+- No false positives on test files
