Memory Engine

A hook-driven memory system for Claude Code that auto-saves session context, hands off work between windows, and learns from repeated mistakes.

UtilitiesIntermediate★ 134⑂ 27AI score 9/10Last updated: May 11, 2026

What it does

  • Smart Context — detects the current project from your working directory and loads that project's memory at session start, with no hardcoded paths.
  • Auto Learn (pitfall detection) — spots retries, error-then-fix sequences, and user corrections before context compaction, saving both the problem and the fix. The same mistake three or more times gets promoted to a permanent rule.
  • Student Loop (/reflect) — an 8-step cycle: note, link, spot patterns, review, refine, re-study, slim down, report.
  • Session Handoff (/handoff) — writes progress, decisions, and unfinished tasks to a file the next Claude Code window auto-detects.
  • Correction Cycle (/analyze) — logs the edits you make by hand, the kind of mistake that never shows up in error logs.
  • Saves at three points (every 20 messages, before compaction, at session end) so you never have to remember a command.

Who it's for

  • Anyone running long multi-session work who keeps losing context to compaction.
  • Developers juggling several projects who want per-project memory kept separate.
  • Multi-device Claude Code users who want memory synced through a GitHub backup repo.
  • People tired of Claude repeating the same mistake and wanting it hardened into a rule.

Examples

  1. Context is about to fill up mid-task → run /handoff, open a fresh window, and the new session picks up the progress file automatically.
  2. End of the week → run /reflect to review the last 7 days, prune stale notes, and upgrade recurring pitfalls into hard rules.
  3. Switching from work laptop to home machine → /sync (memory-backup.sh sync) for two-way sync with the backup repo, then /reload.
  4. MEMORY.md is bloating → /memory-health reports line-count warnings so you can move old content into standalone files.

Install in Claude Code

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the skill folder from the GitHub repo HelloRuru/claude-memory-engine into my ~/.claude/skills/memory-engine/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/HelloRuru/claude-memory-engine.git /tmp/claude-memory-engine && mkdir -p ~/.claude/skills/memory-engine && cp -r /tmp/claude-memory-engine/skill/* ~/.claude/skills/memory-engine/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal and clone the repo: git clone https://github.com/HelloRuru/claude-memory-engine.git
  2. Enter the folder: cd claude-memory-engine
  3. Check the README for an official install script — use it if one exists, since this skill spans hooks, commands, and settings.
  4. Back up your current config: cp -r ~/.claude ~/.claude.bak
  5. Copy the skill: mkdir -p ~/.claude/skills/memory-engine && cp -r skill/* ~/.claude/skills/memory-engine/
  6. Copy the hook scripts into ~/.claude/scripts/hooks/ and the command files into ~/.claude/commands/.
  7. Register the SessionStart, SessionEnd, PreCompact, UserPromptSubmit, and PreToolUse hooks in ~/.claude/settings.json.
  8. For backups, create a private GitHub repo for your memory, point memory-backup.sh at it, and test with memory-backup.sh push.
  9. Restart Claude Code and run /overview or /check to confirm everything is wired up.
