# Codebase health audit

Score your codebase across 7 health categories, identify weak spots, and get a prioritized progression plan. Each category is scored 1-10 with specific, actionable findings.

**Time**: 3-8 minutes depending on codebase size | **Scope**: Full project

## Instructions

You are a senior engineering consultant performing a codebase health assessment. Analyze the project across all 7 categories (or a subset if `$ARGUMENTS` specifies categories), score each one, and produce a progression plan.

If `$ARGUMENTS` contains category names (e.g., "secrets security tests"), only audit those categories. Otherwise, audit all 7.

---

### Category 1: Secrets (weight: 15%)

Scan for hardcoded credentials, API keys, and sensitive data in code.

```bash
# API keys and tokens in code
grep -rn --include="*.{js,ts,py,go,java,rb,php,yaml,yml,json,toml,env,cfg,ini,conf}" \
  -E '(?i)(api[_-]?key|apikey|secret[_-]?key|password|passwd|token|bearer)\s*[=:]\s*["'\''"][^"'\'']{8,}' \
  --exclude-dir={node_modules,vendor,.git,dist,build,target,__pycache__,.venv} . 2>/dev/null | head -20

# Known provider patterns
grep -rn -E 'sk-[a-zA-Z0-9]{20,}|ghp_[a-zA-Z0-9]{36}|AKIA[A-Z0-9]{16}|xox[bps]-[a-zA-Z0-9\-]{20,}' \
  --exclude-dir={node_modules,vendor,.git,dist,build,target} . 2>/dev/null | head -10

# .env files committed
find . -name ".env*" -not -name ".env.example" -not -path "*/node_modules/*" -not -path "*/.git/*" -type f 2>/dev/null

# .gitignore coverage
[ -f ".gitignore" ] && {
  for pattern in ".env" "*.pem" "*.key" "*.p12"; do
    grep -q "$pattern" .gitignore 2>/dev/null && echo "OK: $pattern in .gitignore" || echo "MISSING: $pattern not in .gitignore"
  done
}
```

**Scoring:**
- 10: Zero secrets, .gitignore covers all sensitive patterns, .env.example exists
- 7-9: No secrets in code, minor .gitignore gaps
- 4-6: 1-3 potential secrets found (may be false positives), or .env committed
- 1-3: Multiple secrets in code, private keys committed, no .gitignore protection

---

### Category 2: Security (weight: 15%)

Check for OWASP-style vulnerabilities and unsafe patterns.

```bash
# SQL injection patterns
grep -rn --include="*.{js,ts,py,java,go,rb,php}" \
  -E '(query|execute|exec)\s*\(\s*[`"'\''"].*\+|\$\{|%s|\.format\(' \
  --exclude-dir={node_modules,vendor,.git,dist,build,target,test,__test__} . 2>/dev/null | head -15

# eval/exec usage
grep -rn -E '\b(eval|exec|execSync|Function\(|setTimeout\([^,]*[+`]|setInterval\([^,]*[+`])' \
  --include="*.{js,ts,py}" --exclude-dir={node_modules,vendor,.git,dist} . 2>/dev/null | head -10

# Unsafe deserialization
grep -rn -E '(pickle\.loads|yaml\.load\(|JSON\.parse\(.*user|unserialize\()' \
  --exclude-dir={node_modules,vendor,.git,dist} . 2>/dev/null | head -10

# Missing input validation on routes/endpoints
grep -rn -E '(app\.(get|post|put|delete|patch)|router\.(get|post|put|delete))' \
  --include="*.{js,ts}" --exclude-dir={node_modules,.git,dist} . 2>/dev/null | wc -l
```

**Scoring:**
- 10: No injection patterns, no eval/exec, input validation on all endpoints, CSP headers
- 7-9: Minor issues (1-2 eval usages in non-user-facing code)
- 4-6: Some injection patterns, missing validation on several endpoints
- 1-3: Active SQL injection risk, eval with user input, no input sanitization

---

### Category 3: Dependencies (weight: 15%)

Audit package health, known CVEs, and freshness.

```bash
# Node.js audit
[ -f "package-lock.json" ] && npm audit --json 2>/dev/null | jq '.metadata.vulnerabilities' 2>/dev/null
[ -f "package.json" ] && npx npm-check 2>/dev/null | tail -20

# Python
[ -f "requirements.txt" ] && pip-audit -r requirements.txt 2>/dev/null | tail -20
[ -f "pyproject.toml" ] && pip-audit 2>/dev/null | tail -20

# Rust
[ -f "Cargo.toml" ] && cargo audit 2>/dev/null | tail -20

# Go
[ -f "go.mod" ] && govulncheck ./... 2>/dev/null | tail -20

# Lockfile presence
for lockfile in package-lock.json yarn.lock pnpm-lock.yaml Cargo.lock go.sum poetry.lock; do
  [ -f "$lockfile" ] && echo "OK: $lockfile exists"
done
[ ! -f "package-lock.json" ] && [ ! -f "yarn.lock" ] && [ ! -f "pnpm-lock.yaml" ] && [ -f "package.json" ] && echo "MISSING: No lockfile for Node.js project"
```

**Scoring:**
- 10: Zero CVEs, lockfile present, all dependencies <6 months old
- 7-9: No critical/high CVEs, minor outdated packages
- 4-6: 1-3 high CVEs, or >50% dependencies outdated by a year+
- 1-3: Critical CVEs, no lockfile, abandoned dependencies

---

### Category 4: Structure (weight: 10%)

Evaluate file organization, naming conventions, and module boundaries.

```bash
# File count per top-level directory
for dir in */; do
  [ -d "$dir" ] && [ "$dir" != "node_modules/" ] && [ "$dir" != ".git/" ] && [ "$dir" != "vendor/" ] && \
    echo "$dir: $(find "$dir" -type f -not -path "*/node_modules/*" -not -path "*/.git/*" 2>/dev/null | wc -l) files"
done

# Deeply nested files (complexity indicator)
find . -type f -not -path "*/node_modules/*" -not -path "*/.git/*" -not -path "*/vendor/*" -mindepth 6 2>/dev/null | head -10

# Mixed naming conventions
find . -type f -name "*_*" -not -path "*/node_modules/*" -not -path "*/.git/*" 2>/dev/null | head -5
find . -type f -name "*-*" -not -path "*/node_modules/*" -not -path "*/.git/*" 2>/dev/null | head -5

# Circular dependency indicators (for JS/TS projects)
[ -f "package.json" ] && npx madge --circular --extensions ts,js src/ 2>/dev/null | head -20
```

**Scoring:**
- 10: Clear module boundaries, consistent naming, no circular deps, flat hierarchy
- 7-9: Good structure with minor inconsistencies
- 4-6: Mixed conventions, some circular deps, unclear module boundaries
- 1-3: No clear structure, deeply nested files, widespread circular deps
