# auto-memory

Watches what Claude edits and updates CLAUDE.md in the background. Useful when project memory goes stale after build or structure changes.

## What it does

The plugin hooks into Edit, Write and Bash operations, appends changed file paths to `.claude/auto-memory/dirty-files`, and at the end of a turn spawns an isolated `memory-updater` agent. That agent invokes the `memory-processor` skill, reads the changes and rewrites the relevant CLAUDE.md sections. Because the agent runs in its own context window, your main session tokens stay untouched.

Updates land only inside `<!-- AUTO-MANAGED: ... -->` blocks. Anything between `<!-- MANUAL -->` markers is left alone. Sections cover project description, build commands, architecture, conventions, detected patterns and insights from commit history.

Trigger behaviour lives in `.claude/auto-memory/config.json`. `default` tracks edits in real time; `gitmode` fires only on `git commit`. With no config file, `default` is used. On a commit, the hash and message are stored next to each file path, so memory updates reflect why a change happened, not just which files moved.

## Install

### Claude Code (native platform)

**Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add anthropics/claude-plugins-community
```
In the agent chat (not a shell):
```text
/plugin install auto-memory@claude-community
```

## When to use it
- refresh CLAUDE.md after build commands change
- record a new directory layout in project memory
- pick up edits made outside Claude via git
- keep hand-written notes intact during auto updates
- set up per-package CLAUDE.md files in a monorepo

## Example prompts
- /auto-memory:init
- /auto-memory:sync
- /auto-memory:status

# claude-code-auto-memory

**Your CLAUDE.md, always in sync.** Minimal tokens. Zero config. Just works.

A Claude Code plugin that watches what Claude Code edits, deletes, and moves - then quietly updates your project memory in the background. No manual maintenance needed.

## The Problem

CLAUDE.md files become stale as codebases evolve:

- Build commands change but memory stays outdated
- Architecture shifts go unrecorded
- Code conventions drift without memory updates
- New team members get incorrect context

**Manual maintenance is tedious and often forgotten.**

## The Solution

claude-code-auto-memory automatically updates CLAUDE.md when Claude Code makes changes. Processing happens in an isolated agent, so it doesn't consume your main conversation's context window.

```
Claude Code edits code -> Plugin tracks changes -> Isolated agent updates memory -> Context stays fresh
```

## Features

- **Automatic sync**: Tracks Edit/Write/Bash operations and updates CLAUDE.md at end of turn
- **Bash operation tracking**: Detects rm, mv, git rm, git mv, unlink commands
- **Minimal-token tracking**: PostToolUse hook has no output; stop hook triggers isolated agent
- **Isolated processing**: Agent runs in separate context window, doesn't consume main session tokens
- **Marker-based updates**: Only modifies AUTO-MANAGED sections, preserves manual content
- **Subtree support**: Hierarchical CLAUDE.md for monorepos

## Installation

### From Marketplace

```bash
claude plugin marketplace add severity1/severity1-marketplace
claude plugin install auto-memory@severity1-marketplace
```

### Local Development

```bash
# Add local marketplace
claude plugin marketplace add /path/to/claude-code-auto-memory/.dev-marketplace/.claude-plugin/marketplace.json

# Install from local
claude plugin install auto-memory@local-dev
```

## Commands

### `/auto-memory:init`

Initialize CLAUDE.md structure for your project with an interactive wizard.

```
/auto-memory:init
```

The wizard will:
1. Analyze your codebase structure
2. Detect frameworks and build commands
3. Identify subtree candidates (for monorepos)
4. Present findings for your approval
5. Generate CLAUDE.md with auto-managed sections

### `/auto-memory:calibrate`

Force a full recalibration of all CLAUDE.md files.

```
/auto-memory:calibrate
```

### `/auto-memory:sync`

Sync CLAUDE.md with manual file changes detected by git. Use this when you've edited files outside Claude Code (in your IDE, terminal, etc.) and want to update memory without a full recalibration.

```
/auto-memory:sync
```

Detects:
- Modified tracked files (`git diff`)
- Staged files (`git diff --cached`)
- New untracked files (`git ls-files --others`)

### `/auto-memory:status`

Show current sync status and pending changes.

```
/auto-memory:status
```
