codex-lifecycle-orchestration

End-to-end software development lifecycle orchestration uses a single agent to manage requirements, documentation, work planning, implementation, and quality reporting, eliminating complex subagent coordination.

Enforcing quality gates across project scales uses scale-based phases that adapt workflow complexity for Small, Medium, or Large projects, integrating mandatory checks to ensure code and documentation standards.

Generating and managing PRD, ADR, and design documentation occurs directly within the lifecycle orchestration process, which manages documentation creation alongside requirements, work planning, and implementation phases.

Adapting development workflow complexity based on project size is supported through scale-based phases, which adjust process complexity for Small, Medium, and Large projects while preserving stop points and quality gates.

Single agent orchestration works for large-scale feature development by managing requirements, documentation, implementation, and testing phases. It preserves scale-based phases and quality gates specifically designed for Large project workflows.
