Monitor OpenCode with FrontierStack

OpenCode is an open-source terminal coding agent that works with your choice of model provider. FrontierStack detects the opencode CLI on this Mac or over SSH and offers Homebrew and npm installs. Its MCP pane adds FrontierStack under mcp in ~/.config/opencode/opencode.json and puts the FrontierStack skill in ~/.agents/skills. A commented opencode.jsonc is never rewritten; the entry is shown for you to paste.
