vibe-coding-background-agent

Build background AI agents that run alongside developers during vibe coding sessions, proactively helping without being asked. Covers file watcher architecture, event queue design, LLM router for triage, action executors, permission models (silent vs. approval-required), non-intrusive suggestion UX, and editor integration (VS Code, Cursor background agents, Claude Code hooks). Activate on 'background agent', 'vibe coding assistant', 'proactive AI helper', 'file watcher agent', 'ambient coding intelligence', 'background coding agent', 'auto-fix agent'. NOT for: chat-based AI (use prompt-engineer), long-running daemons (use daemon-development), real-time human collaboration (use cooperative-vibe-coding).
