Shared Configuration

All plugins read from .claude/vibe-hacker.json:

{
  "greenfield_mode": true,
  "greenfield_strict": false,
  "greenfield_patterns": ["deprecated", "legacy", "@deprecated"],
  "priming": {
    "files": ["README.md"],
    "globs": ["docs/planning/action-plans/*.md"],
    "instructions": "Focus on active work."
  },
  "planning": {
    "version": "0.2.1",
    "subdirs": {
      "adr": "decisions",
      "fdp": "designs",
      "ap": "action-plans",
      "report": "reports"
    }
  },
  "protected_paths": {
    "planning_root": "docs/planning",
    "rules": [
      {"pattern": "docs/planning/*/archive/**", "tier": "readonly"}
    ]
  }
}

Each plugin reads only its relevant keys:

• greenfield-mode reads: greenfield_mode, greenfield_strict, greenfield_patterns
• primer reads: priming, greenfield_mode (for display)
• planning reads: planning, protected_paths
• expert-agents reads: nothing (stateless)
