What problem does it solve? Installing agent orchestration skills and editing AGENTS.md or CLAUDE.md routing policy by hand risks overwriting existing developer configuration, breaking symlinks, or silently replacing user-owned files. This Skill enforces a read-only-first workflow with previews, approvals, backups, and rollback guidance. ## Core Features & Use Cases - Safe installation lifecycle: Inspect, preview, install, update, or repair Codex Maestro and Claude Maestro skills, workers, and agents at global or project scope. - Deterministic policy editor: The bundled configure_policy.py script previews a unified diff of the managed orchestration policy block and only writes with --apply, using atomic replacement, timestamped backups, and marker validation. - Conflict protection: Detects modified destinations, symlinks, malformed markers, and legacy worker files, refusing to overwrite anything without explicit user approval. - Use Case: A developer asks their agent to set up Codex Maestro globally; the Skill inspects existing installations, shows the exact AGENTS.md diff, waits for approval, installs the skill and worker definitions, then validates and reports rollback steps. ## Quick Start Ask the agent to set up Agent Toolkit for Codex at global scope and preview every change before applying it.
