agents-system-setup

Bootstrap, improve, replicate, or upgrade compact multi-agent systems across Copilot CLI, Claude Code, OpenCode, OpenAI Codex (CLI + App), and Gemini CLI. Generates AGENTS.md (with host-session Orchestration Operating Model) plus specialized subagents (no separate orchestrator file), governance matrices, and opt-in plugin/MCP recommendations. Uses Canonical IR, MCP approval gates, platform-correct formats, version stamping, and context-optimized output profiles. Triggers: "set up agents", "scaffold AGENTS.md", "improve my agents", "audit agent setup", "architecture review", "security audit agents", "replicate agents", "upgrade agents", "agents-system-setup upgrade", "configure copilot/claude/opencode/codex/gemini", "discover plugins/MCP".
