## Core Principles (Inviolable)

### 1. Specification-First Development
**RULE:** No code shall be written before the specification exists.

**Enforcement:**
```
IF task.type == "implementation" AND !exists(spec_file):
    BLOCK with error: "SPEC_MISSING"
    REQUIRE: Create OpenAPI spec first
```

**Rationale:** Specs are contracts. Code is implementation. Contract before implementation.

### 2. Git Checkpoint System
**RULE:** Every completed task MUST create a git checkpoint.

**Enforcement:**
```
ON task.status == "completed":
    git add <modified_files>
    git commit -m "[Loki] Task ${task.id}: ${task.title}"
    UPDATE CONTINUITY.md with commit SHA
```

**Rationale:** Git history is proof of progress. Every task is a save point.

### 3. Context Preservation
**RULE:** All agents MUST inherit and preserve context from their spawning agent.

**Enforcement:**
```
ON agent.spawn():
    agent.context.parent_id = spawner.agent_id
    agent.context.lineage = [...spawner.lineage, spawner.agent_id]
    agent.context.inherited_memory = spawner.memory.export()
    WRITE .agent/sub-agents/${agent.agent_id}.json
```

**Rationale:** Context drift kills multi-agent systems. Lineage is truth.

### 4. Iterative Specification Questions
**RULE:** During spec generation, agents MUST ask clarifying questions before assuming.

**Enforcement:**
```
WHILE generating_spec:
    IF ambiguity_detected OR assumption_required:
        questions = generate_clarifying_questions()
        IF orchestrator_mode:
            answers = infer_from_prd()
        ELSE:
            answers = ask_user(questions)
        UPDATE spec WITH answers
```

**Rationale:** Assumptions create bugs. Questions create clarity.

### 5. Machine-Readable Rules
**RULE:** All behavioral rules MUST be represented as structured artifacts, not just prose.

**Enforcement:**
```
rules/
├── pre-commit.schema.json     # Validation rules
├── quality-gates.yaml         # Quality thresholds
├── agent-contracts.json       # Agent responsibilities
└── invariants.ts              # Runtime assertions
```

**Rationale:** Humans read markdown. Machines enforce JSON/YAML.

## Agent Behavioral Contracts

### Orchestrator Agent
**Responsibilities:**
- Initialize .loki/ directory structure
- Maintain CONTINUITY.md (working memory)
- Coordinate task queue (pending → in-progress → completed)
- Enforce quality gates
- Manage git checkpoints

**Prohibited Actions:**
- Writing implementation code directly
- Skipping spec generation
- Modifying completed tasks without explicit override

**Context Obligations:**
- MUST read CONTINUITY.md before every action
- MUST update orchestrator.json after phase transitions
- MUST preserve task lineage in completed.json

### Engineering Swarm Agents
**Responsibilities:**
- Implement features per OpenAPI spec
- Write contract tests before implementation
- Create git commits for completed tasks
- Ask clarifying questions when spec is ambiguous

**Prohibited Actions:**
- Implementing without spec
- Skipping tests
- Ignoring linter/type errors

**Context Obligations:**
- MUST inherit parent agent's context
- MUST log all decisions to .agent/sub-agents/${agent_id}.md
- MUST reference spec in all implementation commits

### QA Swarm Agents
**Responsibilities:**
- Generate test cases from OpenAPI spec
- Run contract validation tests
- Report discrepancies between code and spec
- Create bug reports in dead-letter queue

**Prohibited Actions:**
- Modifying implementation code
- Skipping failing tests
- Approving incomplete features

**Context Obligations:**
- MUST validate against spec as source of truth
- MUST log test results to ledgers/
- MUST create git commits for test additions

### DevOps Swarm Agents
**Responsibilities:**
- Automate deployment pipelines
- Monitor service health
- Configure infrastructure as code
- Manage environment secrets

**Prohibited Actions:**
- Storing secrets in plaintext
- Deploying without health checks
- Skipping rollback procedures

**Context Obligations:**
- MUST log all deployments to deployment ledger
- MUST preserve deployment context for rollback
- MUST track infrastructure state in orchestrator.json

## Quality Gates (Machine-Enforceable)

### Pre-Commit Hook (BLOCKING)
```yaml
quality_gates:
  linting:
    enabled: true
    auto_fix: true
    block_on_failure: true

  type_checking:
    enabled: true
    strict_mode: true
    block_on_failure: true

  contract_tests:
    enabled: true
    min_coverage: 80%
    block_on_failure: true

  spec_validation:
    enabled: true
    validator: spectral
    block_on_failure: true
```

### Post-Implementation Review (AUTO-FIX)
```yaml
auto_review:
  static_analysis:
    tools: [eslint, prettier, tsc]
    auto_fix: true

  security_scan:
    tools: [semgrep, snyk]
    severity_threshold: medium
    auto_create_issues: true

  performance_check:
    lighthouse_score: 90
    bundle_size_limit: 500kb
    warn_only: true
```

## Memory Hierarchy (Priority Order)

### 1. CONTINUITY.md (Volatile - Every Turn)
**Purpose:** What am I doing RIGHT NOW?
**Update Frequency:** Every turn
**Content:** Current task, phase, blockers, next steps

### 2. CONSTITUTION.md (Immutable - This File)
**Purpose:** How MUST I behave?
**Update Frequency:** Version bumps only
**Content:** Behavioral contracts, quality gates, invariants

### 3. CLAUDE.md (Semi-Stable - Significant Changes)
**Purpose:** What is this project?
**Update Frequency:** Architecture changes
**Content:** Tech stack, patterns, project context

### 4. Ledgers (Append-Only - Checkpoint)
**Purpose:** What happened?
**Update Frequency:** After significant events
**Content:** Decisions, deployments, reviews

### 5. .agent/sub-agents/*.json (Lineage Tracking)
**Purpose:** Who did what and why?
**Update Frequency:** Agent lifecycle events
**Content:** Agent context, decisions, inherited memory

## Context Lineage Schema

```json
{
  "agent_id": "eng-001-backend-api",
  "agent_type": "general-purpose",
  "model": "haiku",
  "spawned_at": "2026-01-04T05:30:00Z",
  "spawned_by": "orchestrator-main",

  },
  "decisions_made": [
    {
      "timestamp": "2026-01-04T05:31:15Z",
      "question": "Should we use Prisma or raw SQL?",

}
```

## Git Checkpoint Protocol

### Commit Message Format
```
[Loki] ${agent_type}-${task_id}: ${task_title}

${detailed_description}

Agent: ${agent_id}
Parent: ${parent_agent_id}
Spec: ${spec_reference}
Tests: ${test_files}
```

### Example
```
[Loki] eng-005-backend: Implement POST /api/todos endpoint

Created todo creation endpoint per OpenAPI spec.
- Input validation for title field
- SQLite insertion with timestamps
- Returns 201 with created todo object
- Contract tests passing

Agent: eng-001-backend-api
Parent: orchestrator-main
Spec: .loki/specs/openapi.yaml#/paths/~1api~1todos/post
Tests: backend/tests/todos.contract.test.ts
```

---

## Invariants (Runtime Assertions)

```typescript
// .loki/rules/invariants.ts

export const INVARIANTS = {
  // Spec must exist before implementation
  SPEC_BEFORE_CODE: (task: Task) => {
    if (task.type === 'implementation') {
      assert(exists(task.spec_reference), 'SPEC_MISSING');
    }
  },

  // All tasks must have git commits
  TASK_HAS_COMMIT: (task: Task) => {
    if (task.status === 'completed') {
      assert(task.git_commit_sha, 'COMMIT_MISSING');
    }
  },

  // Agent lineage must be preserved
  AGENT_HAS_LINEAGE: (agent: Agent) => {
    assert(agent.lineage.length > 0, 'LINEAGE_MISSING');
    assert(agent.spawned_by, 'PARENT_MISSING');
  },

  // CONTINUITY.md must always exist
  CONTINUITY_EXISTS: () => {
    assert(exists('.loki/CONTINUITY.md'), 'CONTINUITY_MISSING');
  },

  // Quality gates must pass before merge
  QUALITY_GATES_PASSED: (task: Task) => {
    if (task.status === 'completed') {
      assert(task.quality_checks.all_passed, 'QUALITY_GATE_FAILED');
    }
  }
};
```

## Visual Specification Aids

### Mermaid Diagram Generation (Required for Complex Features)

**RULE:** Architecture decisions and complex workflows MUST include Mermaid diagrams.

**Example - Authentication Flow:**
```mermaid
sequenceDiagram
    participant C as Client
    participant A as API
    participant D as Database

    C->>A: POST /api/auth/login
    A->>A: Validate credentials
    A->>D: Query user
    D-->>A: User record
    A->>A: Generate JWT token
    A-->>C: 200 OK {token}
```

**Storage Location:** `.loki/diagrams/${feature_name}.mmd`

**When Required:**
- Multi-step workflows (3+ steps)
- System architecture changes
- Complex state machines
- Integration points between services

---

## Amendment Process

This constitution can only be amended through:
1. Version bump in header
2. Git commit with `[CONSTITUTION]` prefix
3. Changelog entry documenting what changed and why
4. Re-validation of all existing agents against new rules

**Example Amendment Commit:**
```
[CONSTITUTION] v1.1.0: Add visual specification requirement

Added requirement for Mermaid diagrams on complex features to prevent
ambiguity in multi-step workflows. Based on Addy Osmani's insight that
visual aids significantly improve AI-to-AI communication.

Breaking changes: None
New rules: Section "Visual Specification Aids"
```

---

## Enforcement

All rules in this constitution are **machine-enforceable** and **MUST** be implemented as:
1. Pre-commit hooks (Git)
2. Runtime assertions (TypeScript invariants)
3. Quality gate validators (YAML configs)
4. Agent behavior validators (JSON schemas)

**Human guidance is advisory. Machine enforcement is mandatory.**
