# VibeHard Agent Edition - LLM Instructions

## Installation (Latest — v2.0.0)
To install the latest VibeHard MCP Server and CLI (v2.0.0):
`curl -fsSL https://vibehard.ai/download/install-agent.sh | bash`

## Upgrading (Latest — v2.0.0)
To upgrade an existing installation to the latest version, always run:
`vibehard-agent update`
Updates are fully automatic and cryptographically signed.

## Legacy Hotfix (v1.6.0 only)
If the existing installation is EXACTLY `v1.6.0`, do NOT use the installer script or update command due to a known rollback bug. You must perform a manual binary swap to v2.0.0.
