+**Integration with `castquest-code` for autonomous protocol expansion:**
+
+This priority establishes the foundation for AI-powered development workflows within the CastQuest protocol:
+
+- **Autonomous Protocol Expansion**: Integration with `castquest-code` (from SMSDAO) enables automated proposal and scaffolding of new protocol features, contracts, and extensions.
+
+- **Automated Test Generation**: For future V4-only custom contracts following a "reduced external dependency" principle, development agents automatically generate comprehensive unit tests, ensuring code quality and security.
+  - Target for V4-only custom contracts: minimize external dependencies (ideally no new OpenZeppelin imports, no proxies, and pure token operations), while allowing existing core contracts to continue using audited libraries like OpenZeppelin where appropriate
+
+- **CODE Token Reward Mechanism**: Define and implement the CODE token distribution system that rewards validated code contributions from:
+  - Autonomous builders and agents
+  - Smart contract generation and audits
+  - Protocol improvements and optimizations
+  - Documentation and testing contributions
+
+- **Smart Brain Integration**: The protocol's Smart Brain architecture coordinates with development agents to:
+  - Evaluate code quality and security
+  - Validate contributions before CODE token distribution
+  - Track contribution history and reputation
+  - Enable continuous, agent-assisted protocol evolution
+
+**Implementation Tasks**:
+- [ ] Define CODE token reward tiers and validation criteria
+- [ ] Integrate castquest-code agent framework
+- [ ] Build automated contract scaffolding pipeline
+- [ ] Implement test generation for custom contracts
+- [ ] Create contribution validation and audit system
+- [ ] Deploy CODE token minting logic in CodeEngine

+## Agentic Development Integration
+
+V4's Smart Brain architecture is the combined on-chain governance and upgrade surface plus off-chain agent orchestration layer (AI agents, code-generation pipelines, and security tooling) that coordinates agentic development of the protocol. It is specified in more detail in [Smart Brain Architecture](./SmartBrain.md).
+V4's Smart Brain architecture integrates with agentic development frameworks to enable:
+- **Autonomous Protocol Expansion**: AI agents (e.g., castquest-code from SMSDAO) can propose and scaffold new protocol features off-chain
+- **Automated Contract Generation**: Off-chain development agents (via Smart Brain/CI) generate, audit, and deploy smart contracts; the on-chain CodeEngine does not call external systems and only verifies submitted results/metadata
+- **CODE Token Rewards**: Once results are verified on-chain, CodeEngine mints and distributes CODE tokens to reward validated contributions from AI-powered development tools, agentic protocol expansion, and automated smart contract generation
+- **Continuous Evolution**: The protocol evolves through a combination of human governance and AI-assisted, off-chain development, with on-chain contracts remaining pure and free of external dependencies
+
+This creates a flywheel where protocol improvements are incentivized through CODE tokens, enabling sustainable, community-driven growth while preserving the "No External Calls" and "No External Dependencies" guarantees of the on-chain system.
