What problem does it solve? Keeping shared team-wide agent rules consistent across Claude Code and Codex is error-prone: files drift, manual edits diverge, and overwriting a user's existing global config can silently destroy their customizations. This Skill installs a canonical tool-agnostic guideline file to both agents byte-identically, with backup protection and verification. ## Core Features & Use Cases - Byte-identical installation: Copies the canonical references/global-config.md to ~/.claude/CLAUDE.md and ~/.codex/AGENTS.md, verifying with cmp -s so newline or encoding differences never slip through. - Safe overwrite with backup: When an existing target differs, it summarizes the diff, asks for approval, and creates a timestamped .bak copy before replacing anything. - Safe uninstall: Restores a prior backup or deletes the file only when the target still matches canonical; user-modified files are reported as unresolved instead of deleted. - Use Case: A team lead publishes updated shared agent principles and asks the AI to roll them out on a teammate's machine; the Skill installs to both agents, backs up the old configs, and confirms byte-level equality. ## Quick Start Install the global config for Claude Code and Codex, backing up any existing files first.
