Hey HN, I built this because I was frustrated re-explaining my setup every Claude Code session and hitting context limits faster than needed.

  The plugin uses mem0.ai to:

  - Automatically retrieve relevant memories before each prompt (UserPromptSubmit hook)
  - Store conversation context when sessions end (Stop hook)
  - Semantic vector search so only relevant context is injected

  Example: Claude now knows I prefer Python, my tech stack, and project context - without me repeating it.

  Technical details:
  - Pure Python, no dependencies except mem0ai
  - ~120 lines of code per hook
  - Works with Claude Code's official plugin system
  - MIT licensed

  Just submitted a PR to the official Anthropic plugin registry: https://github.com/anthropics/claude-plugins-official/pull/52

  Happy to answer questions about the implementation or Claude Code plugins in general.
