9 Constitutional Articles

Article I: Library-First Principle

Rule: Every feature MUST begin as a standalone library.

Validation:

# Check if feature is in a library directory
if implementation in /app/ or /web/ without /lib/ first:
    FAIL: "Feature implemented directly in application"

Example Compliance:

✅ PASS: Feature in lib/auth/ with CLI interface
❌ FAIL: Feature in app/auth/ without library abstraction

---

Article II: CLI Interface Mandate

Rule: All libraries MUST expose CLI interfaces.

Validation:

# Check for CLI entry point
if library exists and no cli.ts or __main__.py:
    FAIL: "Library missing CLI interface"

Example Compliance:

✅ PASS: lib/auth/cli.ts exists with --login, --logout flags
❌ FAIL: lib/auth/ has no CLI entry point

---

Article III: Test-First Imperative

Rule: NON-NEGOTIABLE: No code before tests.

Validation:

# Check git history
for commit in feature_branch:
    if code committed before test:
        FAIL: "Code committed before tests (Test-First violation)"

Example Compliance:

✅ PASS: tests/auth.test.ts committed before src/auth.ts
❌ FAIL: src/auth.ts committed first

---

Article IV: EARS Requirements Format

Rule: All requirements MUST use EARS patterns.

Validation:

# Check requirements.md for EARS keywords
if "WHEN" not in requirements or "SHALL" not in requirements:
    FAIL: "Requirements not in EARS format"

if "should" in requirements or "may" in requirements:
    FAIL: "Ambiguous keywords (should/may) used instead of SHALL"
