claude-code-memdb-plugin

Claude Code plugin for MemDB memory integration — automatic context injection and conversation persistence.

Features

• Context injection — searches MemDB on every prompt, injects relevant memories as context
• Context-aware search — uses rolling conversation buffer for smarter queries
• Conversation persistence — extracts and saves facts, decisions, preferences to MemDB
• Compaction survival — saves memories before context compaction
• Commands — /memory-search, /memory-add, /memory-delete, /memory-update, /memory-info

Install

claude plugin install /path/to/claude-code-memdb-plugin

Important: Plugin stdin workaround

Claude Code has a known bug where plugin-installed hooks receive empty stdin. Add these to ~/.claude/settings.json manually:

{
  "hooks": {
    "UserPromptSubmit": [{"hooks": [{"type": "command", "command": "node /path/to/plugins/memdb-memory/hooks/memdb-inject.mjs", "timeout": 35}]}],
    "Stop": [{"hooks": [{"type": "command", "command": "node /path/to/plugins/memdb-memory/hooks/memdb-stop.mjs", "timeout": 35}]}],
    "PreCompact": [{"hooks": [{"type": "command", "command": "node /path/to/plugins/memdb-memory/hooks/memdb-precompact.mjs", "timeout": 120}]}]
  }
}

Replace /path/to/ with the actual plugin directory path.
