Summary

Add the ability for claude-mem to capture plan file paths from ExitPlanMode hook and retrieve the previous session's plan in subsequent sessions.

Background

Claude Code plan mode creates temporary plan files (e.g., ~/.claude/plans/*.md) but doesn't persist references across sessions, making it difficult to continue previous planning work.

Testing with a PostToolUse hook confirmed that ExitPlanMode response contains the plan file path:

{
  "tool_response": {
    "filePath": "/Users/username/.claude/plans/federated-wandering-volcano.md",
    "plan": "# Plan content..."
  }
}

Proposed Feature

1. Capture Plan References: On ExitPlanMode invocation, store filePath, plan content, session_id, and timestamp in claude-mem database
2. Query Capability: Add get_last_plan tool or extend search filters to retrieve recent plan file paths
3. Session Continuity: When user instructs "continue from previous plan", provide the plan file path to resume work

P.S. Love the plugin, using it every day!
