# Context Engine

Smart Context Engine maintains conversation state and project continuity across OpenClaw sessions.

## Quick Start

The context engine automatically:
- Restores your last active project on session start
- Saves context periodically (heartbeat) and on session end
- Tracks pending tasks and notes per project

### Commands

- **"remember" / "save context"** - Manually save current context
- **"switch to [project]"** - Switch to a project (creates if doesn't exist)
- **"show projects" / "what are we working on"** - List all projects
- **"summarize" / "where did we leave off"** - Get project summary

## Storage

Projects are stored in: `/home/deus/.openclaw/workspace/memory/projects/`

- `projects.json` - All project data
- `session.json` - Current session state

## Actions

### save_context

Saves the current context including:
- Last topic discussed
- Last file worked on
- Last command executed
- Pending tasks
- Notes

**Trigger:** Explicit mention ("remember", "save context"), session_end, heartbeat

### restore_context

Restores the previous session's context:
- Loads last active project
- Shows "Welcome back to [project]"
- Lists pending tasks if any

**Trigger:** session_start, explicit request

### switch_project

Switches between projects:
- Saves current project context
- Loads or creates new project
- Sets as active

**Trigger:** Explicit mention ("switch to X")

### list_projects

Lists all projects with status indicators:
- Shows active project highlighted
- Displays status (active/paused/completed/archived)
- Shows last session date

**Trigger:** Explicit mention ("show projects", "what are we working on")

### summarize

Generates a summary of the active project:
- Current status
- Pending tasks
- Last topic
- Session history

**Trigger:** Explicit mention ("summarize", "where did we leave off")

## Triggers

| Trigger | Condition | Priority |
|---------|-----------|----------|
| session_start | New session begins | 1 |
| explicit_mention | User says "remember", "save context", "project", "switch to", "show projects", "summarize" | 2 |
| heartbeat | Every ~30 min when enabled | 3 |

## Integration

Works with the MEMORY.md system - updates long-term memory with project summaries.
