Code Relay is a structured protocol for AI coding agents that enables self-bootstrapping, cross-session memory, multi-repo awareness, and safe scoped execution. It solves four core issues: cross-session amnesia via HANDOFF/CHECKPOINT mechanisms, limited context window through proactive state saving, lack of standardized workflow with defined processes like boot sequences and task management, and multi-repo blindness via a workspace structure that provides a global view of all repositories. The protocol operates in two modes: GitHub (using Issues and Project Board for state management) and Local (using files like STATUS.yml and HANDOFF.md). Key features include agent-led boot sequences, worktree isolation for task separation, sub-agent delegation to prevent context window overflow, and SCOPE-based write access control. The repository consists of Markdown and YAML templates that define workflows, configuration, and task structures, designed to be copied into a project and customized.
