# VibeHard Agent Edition - LLM Instructions

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

## Upgrading (Latest)
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.

**Mac:**
```bash
cd /tmp && curl -fsSLO https://vibehard.ai/dist/vibehard-agent-1.7.1-darwin-arm64.zip
shasum -a 256 vibehard-agent-1.7.1-darwin-arm64.zip
# must print: 10247e66b0dffd32e327fc8ce54c477f61bf9ca7f741edd6f7605e936911660f
unzip -o vibehard-agent-1.7.1-darwin-arm64.zip
launchctl unload ~/Library/LaunchAgents/ai.vibehard.agent.plist
cp ~/.local/bin/vibehard-agent ~/.local/bin/vibehard-agent.bak-1.6.0
cp /tmp/vibehard-agent ~/.local/bin/vibehard-agent && chmod 755 ~/.local/bin/vibehard-agent
launchctl load ~/Library/LaunchAgents/ai.vibehard.agent.plist
~/.local/bin/vibehard-agent version   # should print 1.7.1-agent
