What problem does it solve? Managing AI agent skills across projects and platforms involves repetitive CLI commands, scope decisions, and error-prone manual file operations. This Skill translates user intent into the correct nxa CLI commands for installing, upgrading, removing, exporting, and troubleshooting Nexus Skills without treating installed copies as editable source files. ## Core Features & Use Cases - Scoped Install Management: Install individual skills or packs to project or global directories targeting GitHub Copilot, Claude Code, Codex, or the Agent Skills standard. - Safe Upgrade and Removal Workflows: Perform narrow skill-specific upgrades with confirmation handling, and uninstall skills by removing exactly one folder since nxa has no uninstall command. - Install Troubleshooting: Diagnose stale installed copies, wrong scope, missing skills, and routing failures using bundled reference guides. - Use Case: A developer wants to update only the skill-evaluator skill in their project for GitHub Copilot. The Skill detects the context, builds nxa install --upgrade --skill skill-evaluator -a github-copilot, explains the replacement behavior, and verifies the result. ## Quick Start Ask the agent to install a specific Nexus Skill into this project for GitHub Copilot and verify the installed copy.
