Audit

/audit - Multi-Agent Code Audit

Run a comprehensive audit that combines security, performance, architecture, and dependency analysis in one pass.

Target: $ARGUMENTS

When to Use

• Before a production release
• After a major refactor
• During compliance reviews (SOC2, ISO 27001)
• When onboarding to an unfamiliar codebase
• When technical debt feels unmanageable
• NOT for: single-file reviews (use @reviewer instead)

Workflow

Step 1: Scope Definition

Determine audit scope:

IF $ARGUMENTS is a path → audit that path
IF $ARGUMENTS is a module name → find and audit the module
IF $ARGUMENTS is empty → audit entire project

Read the project structure. Identify:

• Total files and lines of code
• Primary language and framework
• Test coverage indicators
• CI/CD configuration

Step 2: Security Audit

Check for OWASP Top 10 vulnerabilities:

Check	What to Look For
Injection	SQL/NoSQL injection, command injection, XSS
Auth	Hardcoded secrets, weak JWT config, missing CSRF
Access Control	Missing auth checks, IDOR, privilege escalation
Cryptography	Weak algorithms, plaintext passwords, missing encryption
Configuration	Debug mode in production, verbose errors, default credentials
Dependencies	Known CVEs in packages
Data Exposure	Sensitive data in logs, responses, or error messages

Run if available:

npm audit --json 2>/dev/null || true
npx eslint --format json $TARGET 2>/dev/null || true

Step 3: Architecture Audit

Check structural integrity:

Check	Criteria
Layer separation	Services don't import from components
Circular dependencies	No import cycles
Naming conventions	Consistent file/function naming
Type safety	TypeScript strict mode, no any abuse
Error handling	Try/catch at boundaries, custom error classes
API contracts	DTOs/schemas at boundaries

Step 4: Performance Audit

Check for performance issues:

Check	What to Look For
Bundle size	Large imports, missing tree-shaking
N+1 queries	Database calls in loops
Memory leaks	Uncleaned listeners, subscriptions, timers
Rendering	Unnecessary re-renders, missing memoization
Network	Missing caching, redundant API calls
Assets	Unoptimized images, missing lazy loading

Step 5: Observability Audit

Check for production readiness observability:

Check	What to Look For
Structured logging	JSON format, consistent fields (timestamp, level, service, traceId)
Error tracking	Errors captured with context (user, request, stack trace)
Health endpoints	/health or equivalent exposed by every service
Metrics	RED metrics (Rate, Errors, Duration) for critical operations
Correlation IDs	Trace/request IDs propagated across service boundaries
Sensitive data	NO passwords, tokens, PII, credit cards in logs

# Check for structured logging
grep -rn "console\.log\|console\.error\|console\.warn" $TARGET --include="*.ts" --include="*.tsx" 2>/dev/null | grep -v "node_modules\|test\|spec" | head -15

# Check for health endpoints
grep -rn "health\|healthcheck\|readiness\|liveness" $TARGET --include="*.ts" --include="*.tsx" 2>/dev/null | head -10

# Check for sensitive data in logs
grep -rn "console\.\|logger\.\|log\." $TARGET --include="*.ts" 2>/dev/null | grep -i "password\|token\|secret\|credit\|ssn" | head -10

Step 6: Accessibility Audit (if frontend detected)

If the project contains frontend code (.tsx, .vue, .svelte, .astro), check:

Check	Criteria
Alt text	All images have descriptive alt attributes
Form labels	All inputs have associated labels or aria-label
Heading hierarchy	Single H1, logical H2-H6, no skipped levels
Keyboard navigation	Interactive elements accessible via keyboard
Color contrast	Text meets WCAG AA 4.5:1 ratio
ARIA usage	Correct roles, states, properties

# Detect frontend code
FRONTEND_FILES=$(find $TARGET -name "*.tsx" -o -name "*.vue" -o -name "*.svelte" -o -name "*.astro" 2>/dev/null | grep -v node_modules | head -5)
if [ -n "$FRONTEND_FILES" ]; then
  echo "Frontend detected - running accessibility checks"
  grep -rn "<img" $TARGET --include="*.tsx" --include="*.vue" 2>/dev/null | grep -v "alt=" | head -10
  grep -rn "<input\|<select" $TARGET --include="*.tsx" --include="*.vue" 2>/dev/null | grep -v "aria-label\|id=" | head -10
fi

Step 7: Dependency Audit

Check dependency health:

Check	What to Look For
Outdated	Major versions behind
Vulnerable	Known CVEs
Unused	Installed but not imported
Duplicate	Multiple versions of same package
License	Incompatible licenses (GPL in MIT project)

Run if available:

npx depcheck --json 2>/dev/null || true

Step 8: Report Generation & Scoring

Compile findings into a structured report with severity ratings.

Scoring formula per domain (0-100):

• Start at 100
• CRITICAL finding: -25 points
• HIGH finding: -15 points
• MEDIUM finding: -10 points
• LOW finding: -5 points
• INFO: -0 points
• Minimum: 0

Overall score = average of all domain scores (weighted: Security 30%, Architecture 25%, Performance 20%, Observability 15%, Dependencies 10%).

Severity Levels

Level	Description	Action
CRITICAL	Security vulnerability or data loss risk	Fix immediately
HIGH	Architecture violation or major performance issue	Fix before release
MEDIUM	Code quality issue or minor vulnerability	Fix in next sprint
LOW	Style issue or minor improvement	Fix when convenient
INFO	Observation or recommendation	Consider for future

Verification Protocol

Before claiming audit is complete:

1. All domains were checked (security, architecture, performance, observability, dependencies, and accessibility if frontend)
2. Every finding has a severity level
3. Every CRITICAL/HIGH finding has a specific remediation step
4. Automated tools were run where available (npm audit, eslint, depcheck)
5. Report includes line-level references for each finding

Anti-Rationalization

Excuse	Reality
"No security issues found"	Absence of evidence is not evidence of absence. Did you check all OWASP categories?
"Architecture looks fine"	Did you trace actual imports, or just scan filenames?
"Dependencies are up to date"	Did you run npm audit? Check for unused deps?
"Performance seems okay"	Did you check for N+1 queries, memory leaks, bundle size?
"The codebase is too large to audit fully"	Scope down to critical paths (auth, payments, data). Never skip security.
"Observability is a nice-to-have"	Production without observability is flying blind. You can't fix what you can't see.
"Accessibility doesn't apply to us"	Internal tools have users with disabilities too. And legal requirements don't have exemptions.

Rules

1. Check all domains - Skipping one defeats the purpose (security, architecture, performance, observability, dependencies + accessibility if frontend)
2. Run automated tools - Never skip npm audit or linting if available
3. Severity must be justified - Every rating needs evidence
4. Remediation is required - Findings without fix suggestions are useless
5. Line references are required - Point to exact files and lines
6. Never assume safety - Verify, don't trust
